Jon Lester, SP
Fast fact: Red Sox were 9-2 in games he started.
Lowdown: He's finally ready. After two seasons marred by a bout with lymphoma, Lester came into camp looking like the Lester of old (or his minor league days). He needs to work on his pitch efficiency, which would let him get deeper into games, but he seems ready. Lester has been following Beckett around since last season, observing his work ethic.
