Who else? The Red Sox have no other options. Maybe you give Alvarez a start, but what do you do when he has a bad start? Not worth rushing Lester, just because the Red Sox lost two games in a row. You guys make it look like we're 8 1/2 back of the Yankees.
The Red Sox have four decent starters in Wells, Schilling, Wakefield, and Beckett. Tread water until you're able to get your team back together. The Yankees aren't good enough to run away with this division.
