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.

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.

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

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
