It’s safe to say that the Boston Red Sox’ starting pitching hasn’t lived up to expectations so far this season. But if there was ever a time to right the ship, it’s now.

Boston will be hosting the division-leading New York Yankees this weekend, with an expected Saturday night showdown between Jon Lester and CC Sabathia.

Lester is only 5-8 with a 5.46 ERA on the season, but with the Red Sox in the wild card hunt and the rival Yankees coming to town, he is looking to have his best stuff on the mound. Boston’s ace has been working in longer throwing sessions on off days, and saw extended bullpen work on Wednesday to help prepare for the Yankees.
