The Washington Nationals (34-23), winners of five of their last seven games, have a chance Sunday to sweep the Boston Red Sox (29-30) in a three-game interleague set. The Washington pitching staff has dominated the Boston bats so far this weekend, and on Sunday Jordan Zimmermann looks to continue that trend when he takes the hill for Davey Johnson's club. Nationals pitchers lead the major leagues with a 2.97 ERA.
Despite a 2.82 ERA, Zimmermann is just 3-5 this season. He is one of just three big league pitchers to have an ERA under 3.00 and a sub-.500 record. In eight interleague outings Zimmermann is 2-2 with a 1.55 ERA.
Jon Lester (3-4, 4.64 ERA) will take the hill for the Red Sox, who have lost five of their past six contests. Lester is just 1-2 with a 6.42 ERA in six Fenway starts this year.
