Game of the day: Milwaukee at Boston, 7:10 p.m. Red Sox left-hander Jon Lester (9-2) will aim to become the first 10-game winner in the majors in this interleague matchup of first-place teams. Lester has earned a win in five of his last six starts, even though his ERA is a pedestrian 4.78 during that stretch. Veteran left-hander Randy Wolf (4-4) will start for Milwaukee, sporting a season ERA (3.20) that is actually more than a half-run better than Lester’s (3.73). Wolf has taken four straight no-decisions, but has allowed one earned run or fewer in three of his last four starts. Lester is 8-2 with a 2.99 ERA in 14 career interleague starts.

Other game to watch:

Pittsburgh at Cleveland, 7:05 p.m. This regional matchup features small-market clubs who are both exceeding modest expectations nearly halfway through the season. The Indians have cooled off considerably after their 30-15 start, but they are still hovering near the top of the American League Central. It’s the middle of June, but Pittsburgh is still above .500 and only a few games out in the National League Central. Left-hander Paul Maholm (3-7) will start for Pittsburgh, coming off scoreless outings in his last two starts and three of his last four. Cleveland right-hander Carlos Carrasco has also thrown two straight scoreless starts, earning 1-0 victories in each of his last two times out.
