Really good point by Mazz today,
"2. How many starters will the Red Sox need in the first round?
The likelihood is four, though that depends on which series the Yankees select. As was the case last year, the American League team with the best record -- in this case, New York -- will have the right to choose its schedule for the first round. If the Yankees choose Series A, that series would begin Wednesday, October 7, and there would be an additional day off between Games 1 and 2. Series B begins Thursday, October 8, with no day off between Game 1 and 2.
So what’s the difference? Because of the additional off-day in Series A, the participating teams would need only three starters. In Series B, four starters are necessary unless a team opts to pitch someone on short rest. Last year, the Angels had the right to choose the series schedule and opted for Series A. Whether the Yankees would do the same remains unclear, particularly because such a decision might allow a team like the Detroit Tigers to throw ace Justin Verlander twice in the first four games.
This season, Verlander is 1-1 with a 1.29 ERA against New York. Allowing him to pitch two of the first four games of a series -- any series -- might be risky. As such, there is a chance the Sox would need only three starters in the first round, in which case Lester and Beckett would each get to pitch twice in a five-game series."
