career years from guys you don't expect it are always huge. Carp played extremely well for the sox last year posting an .885 OPS...but followed that up with a .519. You look at the orioles and the Jays and the great year by pearce and vastly superior bullpen that allowed them to win big games were huge. Machado played more games than lawrie. Wieters only played 26 games, but when you add up the man games lost by janssen, melky, reyes, lind, EE, Rasmus, Morrow it was more than 136 games. Having multiple guys miss time was huge for the Jays because you're stopping and starting. Even when you come back it takes players time to hit their stride even though they are in the lineup.
Winning the close games can arguably be attributed somewhat to managerial decisions...Buck vs Gibby.
