Bronx New World: Most Likely Scenario is Yankees in 6

The Phillies are hanging by a thread, and we're about to see if Charlie Manuel made the right decision by resting Cliff Lee fully and Girardi made the wrong one with short rest for Sabathia/Burnett.

Of the remaining scenarios, 6-game or full 7 game Series, the Yankees have a 53% to do the former, and only a 25% of the latter. If it does go to Game Seven, it will be the single-game Log 5 probability, with the Yankees having the advantage, of course (as you see below).

World Series	H PWP	A PWP	Win	Next Game only
Phillies	0.553	0.592	78%	47%
Yankees	0.621	0.571	22%	53%

H PWP = Home Pythagorean Winning Percentage

A PWP = Away Pythagorean Winning Percentage

These numbers were used to calculate the log5 win probabilities for each team and each game in the series. No I did not look at pitcher vs. team since the sample size is too small. See my post from last year about what it is and how it works.

Yankees Lose! Yankees Win! Yankees ? ? ? ? ? Yes It Could Go 7...

Fret not, Yankees fans: Log 5 Probability is on your side! After a home split leaving the Series at 1-1, the Yankees advantage has only slightly moved down from the first day. A home loss basically dropped their win probability for the Series from 56% to 54%.

Additionally, if you look at the Yankees' winning percentage on the road vs. the Phillies' percentage at home--all of a sudden, home not so sweet home for the Phanatics: .571 vs. .553. I will admit, though, that the number as calculated does NOT take into account the fact that the Yanks winning percentage during the season was accomplished with the DH, not the pitcher, as will be the case in Philadelphia. But it still goes to show that the Yankees are by no means down away from home.

Of the remaining scenarios, 5-game, 6-game or full 7 game Series, the Yankees have the advantage in all of them by roughly 3%-5%, with the most likely outcome being a 7-game Series in which the Yankees have about a 3% chance better than the Phillies to win.

World Series	H PWP	A PWP	Win	Next Game only
Phillies	0.553	0.592	46%	48%
Yankees	0.621	0.571	54%	52%

H PWP = Home Pythagorean Winning Percentage

A PWP = Away Pythagorean Winning Percentage

2009 World Series in a Statshell: New York is Probably Going to Win

Hello fellow baseball travellers, and welcome to the World Series! My friends who favor the Cubs are probably not bothering with this series, but my fellow New Yorkers have brought out their Yankees paraphernalia in full force: World Series-mania has hit the Big Apple with a vengeance. Will A-Rod become the new Mr. October? Will Derek Jeter continue his mastery of November? Will Mark Teixeira, CC Sabathia and AJ Burnett finally bring peace to the long-suffering Gothamites (well, they haven't won either in this century or in this millennium after all...)?

Well, the City of Brothelly Love will certainly try to keep that suffering going longer. What do the numbers say? Well, Yankee's fans, this is your year. I almost didn't even bother running the numbers, thinking it was extremely lop-sided. It actually isn't. While the Bronx Bombers have a 56% chance of winning the Series, that is certainly not the highest probability I've ever seen. I was surprised to find that the Phillies have an excellent Away record (check out the table below), and that the Yankees are a little vulnerable there. Even though they have a better than 50/50 chance of winning, it's only slightly better.

If the Phillies win the first game, it gives them an immediate 61% of taking the series. Of course if the Yanks win it'll be even more dire for the Sons of the Liberty Bell: New York would have a commanding 70/30 chance to win the Series.

Game on!

World Series	H PWP	A PWP	Win	Sweep

Yankees	0.621	0.571	56%	8%

A PWP = Away Pythagorean Winning Percentage

What the Stats Say, vs. What I Think Might Happen: 2009 Baseball Season Predictions Part II

Last month I posted the table you see below. This is how pure stats, using Bill James' Win Shares (though with the Hardball Times version of Win Shares Above Bench--that is, the difference between the player and an average bench player) predicts the upcoming season. I will take this information, and argue where the stats might be pulling a Disraeli. I reproduce the table from the previous post again:

San Francisco	.440	.413	74	88	3
San Diego	.388	.412	63	99	1

Let's start at the top with the AL East. I've looked at the predictions by many of the mainstream sportswriters, like ESPN and Sports Illustrated, and they seem to really discount the Tampa Bay Rays chances. 90% of them seem to think the Yankees are going to somehow end up in first place, with the Red Sox winning the Wild Card. I'll go with the stats and say that the Yankees are basically a 3rd place team in this division. They just did not gain enough to really outdo what they lost from last year (Giambi, Mussina, Abreu, mostly). I do think, though, that the Red Sox will come in 1st place, followed by the Rays, who should get the Wild Card, though it will be close and the same finish as last year could certainly happen again.

In the Central, I fear the White Sox will not have enough to get them to 1st place again, and will fall behind both the Twins and the Indians, but it will be close among the three the whole season. If Mauer stays healthy, along with Morneau, and Liriano can make a comeback--it's the Twins in the playoffs. If Cliff Lee and Fausto Carmona do what they've done in the past, it could be Cleveland. And if the White Sox again over-achieve under Ozzie Guillen, they could steal some October time again.

In the West, it's simple: all Angels--they have no real competition unless disaster strikes.

In the NL East, the stats show a dog-fight between the Mets and the Phillies. I was surprised that Frankie Rodriguez was only worth 7 win shares above bench, considering he set a Saves record. I think the one game statistical difference might be made up by the fact that the Mets will win more games they lead after the 8th inning than they did last year (they lost 11 of these) and that the Phillies will lose more of these (they lost NONE--Brad Lidge had a career season!). Figure Lidge to lose a couple games this year and the Mets to do better under Frankie K. It won't really matter because the runner-up in this division will still move to the playoffs.

Despite the gloom and doom in Cubdom, it will take some major disasters for the Cubs to not make the playoffs again, and of course their problem is how far they will go after they make it. I think they at least get past the first round this year. The Reds might be the most improved in this division, but I still think that St. Louis, under an always-overachieving LaRussa team will still come in 2nd followed by the Brewers.

If Manny decides to go back to being Manny (meaning the Boston Manny), the Dodgers could lose to a good Arizona team, but more than likely, Manny will take his bat into October again.

As It Stands: If the Season Started With the Rosters Today...

Welcome back, loyal readers! The winter is almost over, and we're close to the beginning of the baseball season (I know because the clock just moved forward one hour and daylight lasts until 7pm).

Every year I look at how the Win Shares (as described by Bill James, and calculated for the season by The Hardball Times) have changed via trades and free agent signings. Since three Win Shares equal one win, a team that gains 6 Win Shares by signing free agent would therefore win two more games than they would had they not signed anyone. I go one step further: since a team would likely replace a departing player with at least an average player, I prefer to use Hardball Times' Win Shares Above Bench, meaning that the player in question is worth that many more wins over a replacement average player.

Let's look at an example: the World Champion Philadelphia Phillies. In the offseason, they've done the following, with their accompanying Win Shares gained/lost:

• Lost Pat Burrell (9 WSAB)
• Signed Raul Ibanez (11 WSAB)
• Signed Chan Ho Park (3 WSAB)
• a bunch of releases and signings that net to roughly zero

The Phillies adjusted Pythagorean Record last year was 91 wins. Subtract Burrell's 9 WSAB, add in Ibanez (11) and Park (3) which equals 14-9=5, divide by 3 to get the additional wins, in this case 2. Therefore, based on last year's Phillies' team doing roughly the same all else being equal would win two more games because of the roster changes. I followed this same basic process for all the teams, and the result is the following table:

AL
EAST	2008 WP	2008 P WP	P W+new	P L	Win Shares Net
Tampa Bay	.600	.572	99	63	2
Boston	.588	.600	98	64	2

San Francisco	.440	.413	74	88	3
San Diego	.388	.412	63	99	1

The biggest winner in the AL is Oakland, although unfortunately those 4 games will likely only translate into a 2nd place finish. The biggest loser in that league will be the Rangers. The most interesting story will probably be the AL East, where it looks like Boston and Tampa Bay will again be neck and neck for the season, with the Yankees coming a close 3rd.

The Yankees are interesting: they added Teixeira (13), Sabathia (18), Burnett (8)--a whopping 39 WSAB (or roughly 13 wins above replacement players)! Unfortunately, though, they lost Mussina (13), Abreu (11), and Giambi (6), or 30/3 = 10 games, which you can see shows where they gain 3 games in the standings.

In the NL, the most improved team will be the Braves, but the biggest winner is the Cubs, on the strength of the Brewers being the biggest losers (9 games in the standings!). Losing Sheets (11), Sabathia (13), and on lesser level, Shouse (4) for a total of 28 WSAB lost.

Even with all the changes, the only race that looks like it would change from last year is that the Twins would beat the White Sox by two games.

Keep in mind, that this is using the stats from last season, and while the best predictor of the future is the past, that doesn't mean that it always ends up that way--look at the stock market from last year to this year for case in point.

If there is any more activity prior to the beginning of the season, I will duly note the changes.

Winning the First Game on the Road Gives Huge Boost to Win Probability for Phillies

WS	H PWP	A PWP	Win	Sweep
Rays	0.628	0.515	30%	0%
Phillies	0.598	0.561	70%	16%

Taking away the home-field advantage from the Rays puts the Phillies in position to do what they could not in 1993: win the World Series. Although they do have 70% chance of winning now, the Rays still have a 60% chance of winning Game 2, which could swing things back to at least toss-up status.

Phillies Are No Slouches--Rays Have a Tough Series Even With Home Advantage

Back when the Cubs were the team to beat, I always thought the Phillies would present the toughest challenge. I should have known better that, once October rolls around, even a team made up of Florida Seniors could beat them. One thing I also knew, is that both Boston or Tampa Bay were better than any NL team. So if we look at the numbers alone, sans context, the World Series will be a toss-up, with the slight advantage going to the Phillies, based on their Road record particularly. 

The big caveat in this, though, is that the Phils play in the National League which is not as strong a league as the AL, and particularly not as strong as the survivor of the AL East, which is a beast (and I will stop the rhyme there).

Whoever wins the first game will certainly get the edge, because then, in either case, that winner will hold a 70% chance of taking the Series.

WS	H PWP	A PWP	Win	Sweep
Rays	0.628	0.515	49%	5%
Phillies	0.598	0.561	51%	7%

Home for Three

Rays are back in it, as are the Dodgers. The Dodgers have the second best winning percentage at home, Red Sox have the best. I bet LA will win at least one more home game. The Red Sox could very well sweep at home (hence the great chance of winning still, even though the series is 1-1).

ALCS	H PWP	A PWP	Win	Sweep
Rays	0.628	0.515	41%	0%
Red Sox	0.652	0.534	59%	0%
NLDS
Phillies	0.598	0.561	72%	0%
Dodgers	0.637	0.407	28%	0%

According to Hoyle...

Odds for the Phillies making it to the Series have gone up sharply with their two victories, and winning the first game has made a world (series) of difference for the Red Sox, who now are most likely to win the series. The Dodgers home winning percentage probably means that they should be able to win at least one at home, but the Phillies are no slouches on the road.

ALCS	H PWP	A PWP	Win	Sweep
Rays	0.628	0.515	30%	0%
Red Sox	0.652	0.534	70%	16%
NLDS
Phillies	0.598	0.561	82%	18%
Dodgers	0.637	0.407	18%	0%

Who Will Be Here Today, Gone Tomorrow?

Rays/Red Sox is a toss-up--couldn't be a closer matchup. I thought at the beginning of the year that the Red Sox were the best team in the majors and there's no reason to change my mind now. My initial (though un-posted) prediction of the World Series was BoSox over the Cubs. Insert lamentation here. Or just insert Phillies.

This is looking kind of like last year, where I had the Cubs beating Arizona, and Phillies beating the Rockies. Then I had Arizona beating the Rockies--I wasn't right until I finally had the Red Sox over the Rockies. But the numbers don't lie: the Phils are better than the commuter-train-dodgers (sorry, that's bad). If the Dodgers can demoralize the Phillies by taking two in the City of Brothelly Love, they can pull off an upset again.

ALCS	H PWP	A PWP	Win	Sweep
Rays	0.628	0.515	49%	19%
Red Sox	0.652	0.534	51%	13%
NLCS
Phillies	0.598	0.561	66%	22%
Dodgers	0.637	0.407	34%	10%

Die Another Day

The Angels and White Sox live to fight another day and keep slim hopes alive: both of them have the exact same odds to overcome, a 1 in 5 chance of winning their ALDS series. And in case you so enjoyed my anatomy of a stat, here's another one. What are the chances of the White Sox facing the Angels in the ALCS?

1/5 x 1/5 (each is the chance that they will make it to the next round) = 1/25 or 1 in 25 chances would this happen. I've seen worse odds...

Congratulations to the LA Party Poopers, I mean Dodgers, and the Phillies.

Early Bleakness of Winter Descending on Chicago and Milwaukee...

...Yes, and dramatically so. Of all the teams down 2-0, the Cubs have the slightly better chance of being able to pull through than the others, with their Southside rivals being next in line (especially because of the two home games, potentially, that they could play). In today's games, specifically, the Cubs have a 45% chance of winning and the Brewers have a 42% chance of winning. If they pull it off, they could change some odds for the better. But yes, it looks bleak now.

As for the weather forecast in Southern California, particularly Anaheim way, there's a 92% chance of anomie and despair, though there is also a 99% chance of clear skies.

Anatomy of a Baseball Stat: Explaining Win Probability

Since many of you might not read Bill James' Baseball Manifestos, I thought I would show you how arrive at the numbers that I've been showing as the probability of victory for any given playoff team. We will draw upon two formulas from Bill James, one from his 1981 Baseball Abstract and the other from his 1984 Baseball Abstract.

First, let's look at his Pythagorean Win Expectancy "theorem". I use quotes because even though he called it that, he never thought that it quite stood the test of an actual mathematical theorem. Baseball, at it's most basic, yet most accurate, is a game whose outcome is determined by how many runs the teams score. This has two four points: runs scored by both teams and runs given up by both teams. The obvious: the team with more runs after 9 innings wins. So, he combined the idea of the pythagorean theorem that you all probably still remember (and aren't you glad that's so--I'm sure you've used it to determine the long side of a right triangle given the two short sides recently!): a² + b² = c²

Now this has led to countless important discoveries, not the least of which couldn't have happened without it, Algebra and Trigonometry. So James' basic idea was that there was some correlation between runs scored, and runs given up, and somehow coming up with wins. I don't recall the details now (I first came across this in the late '80s). But the formula that he came up with (which I've detailed elsewhere before) is:

P WP = R² / R² + RA²

P WP = Predicted Winning Percentage

R = Runs Scored (batting)

RA = Runs Given Up (pitching)

So as an example, let's compute this for the Cubs this season. Cubs scored 854 and gave up 668 runs.

P WP = 854² / 854² + 668² = .620

This is the number that was used to compute the predictive standings. But for the Playoffs, I get more granular, since the games encompass playing 3 at home and 2 on the road. For that, I consult ESPN, but this time, get their extended team stats and sort by home and away runs/runs-against.

So the Cubs then end up at:

Home: P WP = 854² / 454² + 339² = .649

Away: P WP = 854² / 401² + 332² = .563

So this is where we want to see what their chances of winning a home game and winning an away game are against their opponent, the LA Dodgers. This is when we bring in James' second discovery which he called Log5 probability (I won't go into the details of the name, that's totally straining your staying power!). Log5 allows you to take the winning percentage of any team, multiply it by their opponent, and come up with a probability of victory (or defeat, as the case might be). Now, because actual winning percentage can sometimes be a function of luck or other external factors, I use the pythagorean or predicted winning percentage.

To do this, I also need the same information for the opposing team, in this case the Dodgers. I'll use the same method and come up with their home and away winning percentages, which are .637 and .454, respectively. So the formula will then look like this:

One Game Win Probability (Cubs home advantage)

 = CHPWP - (CHPWP x LAAPWP) / CHPWP + LAAPWP - (2 x LAAPWP x CHPWP) where

CHPWP = Cubs Home Predicted Winning Percentage

LAAPWP = Dodgers Away Predicted Winning Percentage

With the numbers just given, the formula and result look like this:

Cubs Win Probability = .649 x .454 / .649 + .454 - (2 x .454 x .649) = .690 or 69%

LA Dodgers Win Probability = 1 - Cubs Win Probability = .310 or 31%

The next step is the one I outlined briefly early this week and referenced in the Diamond Mind article of Monday's post, where you assemble all the potential probabilities of the different scenarios in a 5-game series: sweep 3, lose first and win next 3, lose first 2 win next 3, etc. Each one of these is associated with a probability. So, as an example, how do we calculate the probability of a 3-game sweep for these two teams? We simply use the multiplicative property of probabilities. The Cubs have a probability of winning each of the first two home games of .690. The already calculated chance following the above Log5 method for the Away games are .454. The formula and result:

Probability of 3-game sweep for Cubs = .690 x .690 x .454 = 22%

For the Dodgers, the chance of a sweep is only 5%. But since the Cubs lost the two games at home, the chance of a sweep for the Dodgers went up:

Probability of Dodgers Sweep with two victories = 1.00 x 1.00 x .546 = 55% 

(1.00 represents a victory or probability of 100% of winning that game which we know they won)

Hopefully, this has been properly explained. Now to go back to the Red Sox vs. Angels game!

Mirage in Chicago

I'm sorry for any Red Sox, or Cleveland, Phillies, or San Francisco fan out there, but there is no worse fan that one can be than of the Cursed Cubs. They lose when they're predicted to lose, and they lose when they're predicted to win. In short, all they really do is lose. It's not a curse--that is ridiculous. But the negativity surrounding this team is palpable: fans don't cheer when they're behind, the players take on all the expectations of finally being "the one" that they inevitably press and try too hard, and inevitably as well, lose. Game after game. Home field advantage or not, they lose. As the game goes on, rather than trying to calm down and get good at-bats, they swing at pitches in the dirt like single-A minor leaguers. Pitchers overpitch and end up walking everyone they face. If you're a Cubs fan, that is the most pathetic thing to be. In the Cubs' sabermetric world, the usual saying is the same, except let me put it in mathematical notation: Wait 'til Next Year = Cubs + October + (Win Expectancy > 0) = ∞ / 0

Rays and Red Sox Increase Their Odds, Things Look Bad For Angels and White Sox

The Angels and the White Sox have basically a 1 in 4 chance of making it to the ALCS. Looks like I might not be able to spin out my long-awaited probability of the Cubs meeting the White Sox in the World Series.

The Phillies are playing right now and beating Sabathia badly. The question on the Hot Stove circuit will certainly be "Is it too many starts on 3-days rest down the stretch or is he just not a 'clutch' or capable playoff pitcher?" Last year in the playoffs, his ERA was 9.00...

2 Games in the Can, Two Teams with a Better Chance to Win...

Even though the Cubs lost their first game, they still have a 42% chance to win the series, and that's expecting more losses. If the Cubs win the next one, it becomes a slightly better than 50/50 proposition.

The Phillies have taken a commanding position over the Brewers, but we'll certainly see what happens after Sabathia pitches.

Stay tuned for Red Sox-Angels...

I Guess That Answer's Last Night's Question; Now Updated Playoff Odds

No real changes except that we now have the actual contestants and final runs/runs against. Basically, I still think the Red Sox will beat the Angels (57% chance to do so); Rays will beat the White Sox (61%--Sorry, Chicago, no subway series); Cubs will beat the Dodgers (68%); and even though the Phillies have a 53% chance to beat the Brewers, that is really a toss-up.

ALDS	H PWP	A PWP	Win	Sweep
Angels	0.539	0.556	43%	10%
Red Sox	0.652	0.534	57%	15%
Rays	0.628	0.515	61%	17%
White Sox	0.644	0.441	39%	6%
NLDS
Cubs	0.649	0.593	68%	22%
Dodgers	0.637	0.454	32%	5%
Phillies	0.598	0.561	53%	14%
Brewers	0.635	0.522	47%	10%

And if each of the teams predicted to lose the series wins the first game, it changes the odds to plus 60% for all of those teams, except one, the Cubs. They would no longer be favored, but the odds would be just under 50/50 for them to pull it out anyway.

White Sox Vs. Twins in One-Game Playoff Tomorrow--Who Wins?

Based on the fact that White Sox are at home tomorrow, where they sport a lofty 0.643 pythagorean winning percentage, and that the Twins will bring their less-than-stellar 0.450 pythagorean road winning percentage, the Sox have a 69% chance of facing the Rays on Thursday, using the log5 win probability.

White Sox Have Good Chance to Tie for the NL Central Title Tomorrow

The White Sox have a 67% chance of beating the Tigers tomorrow and taking this into a Tuesday one-game playoff with the Twins. Very cool.

Playoff Prediction or Fun With Pythagorean, Log5 and Probabilities: Cubs, Phillies, Red Sox Will Advance

Alright folks (all 60 of you now!), you'll hear it here first: the Red Sox will upset the Angels. The Red Sox have an almost 60% chance of taking the series, mostly on the strength of better record on the road, and an unbelievable record at home.

The Rays will almost certainly beat whoever they play, be it the depleted Twins or depleted White Sox.

The Cubs, on the strength of an excellent road record, also have a great chance to proceed to the NLCS, 67% (the most of any of the post-season aspirants). Their home record vs. the road record of the Dodgers is very big, and their excellent road record can almost nullify the great home advantage of the Dodgers. On the other hand, should the Dodgers steal one at Wrigley, that would probably have a significant effect on the outcome.

Phillies should beat the Brewers (57% chance), and that might be more true considering how much Milwaukee's staff was battered and overworked in the last week (except when CC Sabathia pitched).

H PWP = Home Pythagorean Winning Percentage

A PWP = Away Pythagorean Winning Percentage

These numbers were used to calculate the log5 win probabilities for each team and each game in the series. No I did not look at pitcher vs. team since the sample size is too small.
