Jon Lester put on disabled list by Boston Red Sox - ESPN Boston

Big blow for the Red Sox losing their ace for a possible four weeks. Lester has had a great year leading the Saux in IP, SO, GS and Wins while having a 3.31 ERA. The good news is there is an All Star break and the schedule after the break is fairly easy over the worst possible four weeks Lester could miss. Rotation is going to have to step it up in his absence.
