It's the schedule. The Yanks finish the last 6 games on the road and the Red Sox the last 6 at home.
Yanks play one more at home v O's (automatic win most likely) then face a little tougher competition with a 4 game home stand vs Toronto. Then play 3 at Tampa Bay and 3 at Baltimore.
Red Sox play one more at Toronto and fly south for 3 at Tampa Bay then finish at home with two against Oakland and four against Minnesota.
Don't let anyone kid you The Red Sox will be thrilled if the Yanks have to play Anaheim in the first round. Even if it means being the Wild Card.
