How it happened: Jon Lester and Jake Peavy were both dominant, but the Red Sox touched Peavy up for the lone run of the game in the fourth when Adrian Gonzalez singled in Ryan Sweeney. Sweeney went 2-for-4 with a double and a run scored on the night. Lester had struggled in his previous two outings, giving up 12 runs and walking eight in a combined nine innings. However, on Saturday, Lester performed like the ace he's expected to be for the Red Sox, dominating in his seven innings of work. Lester allowed no runs and five hits, while striking out seven and walking one. The bullpen did the rest, as Franklin Morales, Vicente Padilla and Alfredo Aceves combined to toss two shutout innings to finish out the game. The pen has given up only one run in the 15 2/3 innings Boston relievers have worked since their implosion against the New York Yankees on April 21.
What it means: The Red Sox are obviously playing their best ball of the young 2012 season as they get to the break-even point for the first time all year at 10-10. During their six-game winning streak, they've been doing most of their damage with the bats, but on Saturday they relied on the arm of Lester, as the offense failed to put up at least six runs for the first time in seven games.
Outside the box: Saturday marked the first time the Red Sox held an opponent scoreless since Sept. 6 last season. Lester was on the mound for that game as well.
Up next: Josh Beckett (2-2, 4.56) tries to lead the Red Sox to a four-game sweep over the White Sox. Gavin Floyd (1-3, 3.60) toes the rubber for Chicago at U.S. Cellular Field on Sunday at 2:10 p.m. ET.
