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.

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).

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.

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.

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...

Brewers	0.635	0.522	31%	0%

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%

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).

1: I Think It'll Be A Playoff Game For the Mets/Brewers; Twins Will Upset the White Sox

I had predicted a Subway Series back in June. Did the Carlos Quentin injury do in the Sox? How about the Contreras injury? In either case, it doesn't look good for the Sox, who have to win their last game and hope that the Royals sweep the Twins.

It's definitely looking like the Brewers and Mets will end up in a one-game playoff. Santana was rock-solid today, but it's the unpredictable Oliver Perez going tomorrow for the Mets, and the very predictable and wins except against the Cubs, CC Sabathia.

I love this game!

Mets Win, Chances to Tie/Win Go Up

The chances of a one-game playoff between the Mets and the Brewers just went up to 82% with the Mets' victory. Brewer's chance to win outright drops to 56%.

Fun With Probabilities: Brewers/Twins have best shot at postseason

I'm sure every one of my 34 regular readers (according to Google Analytics!) went immediately to their trusty Texas Instruments TI-35 calculators and used my probabilities from yesterdays' posts to calculate overall odds of making the post season for their favorite teams.

You mean you didn't?

OK, then, let's take a look from the spreadsheet. The beauty of probabilities, statistically speaking is that they can be added, subtracted and multiplied to come up with odds of combinations and odds of mutual exclusivity, among the many other possibilities. Here, we'll really look at the combinatorial property.

Before I delve into this, I want to point out that the best description of what I'm doing comes from DiamondMind Baseball. I first posted my playoff version of Bill James Log5 theorem in 2005. What I will be doing in the playoffs is exactly what they describe. You can also find my original description on BigShouldersSports, where I used to occasionally contribute. In essence, I take the home team's winning percentage at home vs. the away teams road winning percentage, all using the pythagorean expectations formula as used during the season, to compute a probability of victory in each game of the series. I then use the combinatorial mathematics to come up with the odds of sweeping, winning two games, or winning just one for each team. As you will see in the playoffs, this also will take into account all five or seven games.

For now, though, we've already had one game, so the odds have changed a little. Looking at the numbers for the Brewers, they have a 49% chance of beating the Cubs twice (since they won last night). The Mets have only a 29% chance of winning two games. The Brewers also have a 33% of winning one game, Mets have a 50% of doing so, facing easier competition. If both teams win one game or both teams win two games, then they end up tied, so we add up both of those probabilities for each team and multiply to get the odds of this happening, which is 64%.

But unfortunately, for the Mets, because they lost yesterday, they do not have the ability to sweep their series and will therefore have to hope that the Brewers will lose at least one game. Otherwise, the chances of the Brewers winning the Wild Card are 59% (odds of sweeping plus odds of winning two games plus odds of winning one game while the Mets lose two plus Mets losing one plus Mets being swept). Those same odds in reverse, i.e. for the Mets to win the WC, are 41%.

If you're wondering why some of those numbers don't total one hundred, it's because these possibilities are mutually exclusive, meaning they exist on their own (this is something I'm sure my regular visitors already know, but I include it in case I get some new visitors that might not). That is not true, though, for the Mets probability (P) of winning, that is exactly 41% because it is calculated 100% (Mets OR Brewers win P) minus 59% (Brewers win P).

Calculating the same for the White Sox and Twins, we get, respectively, 43% and 57%. Best way to check a probability is to do a gut-level check: Twins are playing the Royals, who are the worst team in the league, whereas the Sox are playing the Indians, which are in third place in the division. So the Sox have a tougher schedule.

Updated, and Now, AL, too

Updated probabilities, plus I've finally included the White Sox and Twins. So how does it look for our finalists, some of whom will go home with consolation prizes (a higher draft pick next summer?).

Important places to look below: the Brewers have an 18% chance to sweep the Cubs, but even if they win only two, their chances of winning two now is almost 50/50. That is in stark contrast to the Mets who have only a 50/50 chance of winning ONE game. The Phillies have practically clinched, so they're not even in the equation anymore. If the Brewers win one more game, that will probably knock the Mets off (sorry, Mets fans).

I think I have to say sorry to White Sox fans also: they have to win the next two games to guarantee a tie, whereas the Twins, winning two games, will win the division. In the immortal words of The Jam, "Here Comes The Weekend"!

Final Weekend: National League Version

The table below is the Log5 probability (I will explain this in a following post) of the possible results in this weekends NL games with Playoff implications. The three columns are probability of a sweep for each team, for getting two wins, and getting one win.

The Brewers and Mets need to win 2 games and the Mets have the best chance of doing that. The numbers absolutely favor the Phillies winning at least one game and very likely two, and the Mets are second most likely to win. Of course, will the Cubs bring their A-Team this weekend? Given what I saw last night in Shea Stadium, they probably won't. Of course, the B-Team sure didn't disappoint too badly.

	sweep	2-wins	1-win
Cubs	19.3%	42.3%	30.9%
Brewers	7.5%	30.9%	42.3%
Phillies	30.6%	44.4%	21.5%
Nationals	3.5%	21.5%	44.4%
Mets	15.2%	39.8%	34.8%
Marlins	10.1%	34.8%	39.8%

Ed note: My original post incorrectly showed the Cubs as the home team, and they are in fact the visiting team in Milwaukee. The numbers changed slightly.

3: Twins' Dome Sweeps the Sox Out of First, Mets/Brewers Tied--2 games for Any One of Them Will Put Them in the Playoffs

The Mets great game tonight keeps them in contention with the Brewers after their extra inning affair. Boy--the Pirates are the tonic for what ails you in the NL. And the Twins now have the upper hand over the White Sox. This is going to be a great weekend for baseball!

4: White Sox Need to Win Two More Games; One-Game Playoff Between Mets & Brewers?

And it would help if they win one of those tomorrow against the Twins or there will be no chance for a Subway Series this year, just in time for the 102nd anniversary of the first one (Cubs vs. Sox in 1906).

And interestingly, the Phillies should still win the NL East, and it looks like a tie now between the Brewers and hapless Mets (subject of a special post from the game tomorrow at Shea Stadium). The Cubs are practically in the weird position to pick their opponent for the NLCS.

5: All the Phillies Met at a Brewer-y; White Sox Have Twins?

There's really only one race in the NL, but with two parts: Phillies over Mets, Mets over Brewers. I think the Brewers are going to come up short based on who they have to play over the weekend, but it should still be interesting.

In the AL, it's just one race, Sox vs. Twins. The Sox should be able to eke it out, but the Twins are not going down easy. This closeness is probably the one game of difference Carlos Quentin's injury has wrought.

The White Sox, the Dodgers, and the Mets only need to win two more games to effectively clinch the playoffs. I still have egg on my face from making that call for the Mets last year, but I'm sure they'll be able to do it given their stats.

The Red Sox and Phillies will both effectively clinch with one more win, but barring a monstrous collapse, both will be in the playoffs. Actually, in a preview of those, Boston is by far the scariest team to face, and the Angels do have something to worry about. In this table (without my log5 win probability calculated completely, yet), note that the Sox are underperforming by 4 games, while the Angels are OVERperforming by 11. That's an amazing number and one that I have not seen in a first place team at the end of the season in the 5 years I've been doing this. Is it the Angels' great relief, namely Frankie K? Great managing? I don't know, but if I was a betting man, I would put money on Boston to take them out in the first round.
