Today's scheduled home plate umpire is Wally Bell. Boston has beaten Baltimore the last three times Bell has called a game between the two teams. Lester has pitched with Bell called balls and strikes once, and Boston won that game. Daniel Cabrera lost his only game pitched with Bell behind home plate.
Bell is a pitchers' umpire with, IIRC, a wide strike zone. Considering that and the afternoon getaway game, I expect a low-scoring matchup.

The individuals playing for Boston and Baltimore may also affect the outcome of the game.
