A Series of Imaginable Significance
Unlike Terry Francona and Joe Girardi, I care who wins the American League East pennant. The three-game series between their clubs, which begins tonight in Boston, will shape that pennant race in important ways. This would be a bigger deal if either the Red Sox or Yankees, as organizations, appeared to care about the outcome of the race. With both teams secure in their playoff berths, barring historic meltdowns, we are unlikely to see three games managed with any particular intensity. But I still care. The pennant is still real to me, dammit.
So, with that in mind, I fired up the ol’ binomial spreadsheet to see what effect this series projects to have on the divisional race – I used the W% number from BPro as my estimate of team quality, and I did not adjust for schedule strength or home/road split, because that would take more work. I’m considering a divisional tie as a “win” for the Red Sox, since they have the tie-breaker clinched and would be the technical division winners in the case of a tie. It wouldn’t be quite the same as winning the East for real, though.
I found that the outcome of this series projects to have a very large impact on the outcome of the race. These are the probabilities of the Red Sox winning, or “winning”, the division based on series outcomes:
Sox win 3-0: 93% chance of winning AL East
Sox win 2-1: 81%
Sox lose 1-2: 62%
Sox lose 0-3: 29%
The game-and-a-half lead the Sox opened up in the last week means that only a Yankee sweep puts the Red Sox in bad shape for the pennant, but the possible swing between a 3-in-10 and a 9-in-10 shot at the AL East crown is a big one. The Red Sox will have significant advantages in the pitching matchups for games two and three, and a significant disadvantage for the first game. I’d certainly be happy with a two-out-of-three outcome, but ballgames are determined by the starting pitching matchup less often than it usually feels like they will be, going into the games.

1. Joel W Posted: August 30, 2011 at 06:24 PM (#3912466)I think this is generally underappreciated, myself included. We should definitely expect the Sox to take two of three, and should be mildly disappointed by any worse outcome.
Appreciating that starting pitching fact means that we should also probably care more to face Detroit than Texas that "ZOMG Verlander twice" suggests. The Tigers give up 3 runs per game in Verlander starts, which I imagine is against about an average offense. The Red Sox are 25% better than average against right handers. Simplifying a bit (a lot), the Red Sox should expect to score about 4 runs in each of their games against Verlander. I think this probably overstates Verlander's ability a little bit, since Verlander is a) outperforming his FIP and b) our expectation of his true talent level shouldn't just include this year (though of course, the same can be said for the Sox lineup).
I didn't mean to turn this into a post about the playoffs, but instead just wanted to say that Detroit isn't *that* good even getting Verlander twice, Texas is a very good team, 4th best in baseball probably, and winning the division and facing Detroit with home-field rather than Texas on the road does matter, with some real probability, to the team's chances of winning the World Series. So, you know, go Sox.
The pitching matchups favor the Sox taking two of three, but I'm agreed with MCoA that pitching matchups tend to predict outcomes less often than I expect. The Yankees and Red Sox are probably about equal right now, I don't think you ever "expect" to win a three game series against a basically equivalent team. I'm less concerned about the wins and losses and just want to see the Red Sox play well. With Youkilis out for the Red Sox, and ARod and Jeter maybe out for the Yankees, I don't see these games as being predictive of much, even three blowout losses.
I'm finding myself surprisingly uninvested in the outcome of this series. I'm pretty confident in this Red Sox team.
And as much as I value the division, I can't seem to get worked up about this either. The Sox are a little banged up, they're still playing good baseball, and they don't seem to be treating games as exhibitions. If they end up falling behind this very good Yankee team, it won't kill me the way it would have in 2007.
The last time Boston went 40 games over .500 in a run of any length was 1949 (90-47, 43 games over .500). They've gone 39 games over .500 three times since: 1950 (86-47), 1978 (84-45) and this year.
I have fully accepted that the Red Sox will not sacrifice a mote or iota of playoff EV for the division, but I care about it anyway.
that right there is why neither manager is willing to put himself on the line for this series. there's a lot to lose, but not much to gain. both teams are virtually assured of a playoff spot, and while the division champs thing is important, only 1 of these teams will be that, so there's really no upside for either manager to profess the importance of it.
An unknowable "if," of course: with an imperative to beat the other club, either the Sox or Yankees might have pulled away by now.
