Cleveland has been on a ridiculous tear. Granted, the bulk of it was against a struggling Tigers team, a useless White Sox team, and an AAA team wearing Twins uniforms. But they did win.
The Yankees 8 game winning streak looks good, but they also beat up on 2 last place teams for those wins.
Boston didnt look as impressive down the stretch, but they were playing against teams fighting for postseason spots, and did manage to do pretty well against them.
