Two players making their major league debuts. Another making his professional debut at a new position. And Jon Lester putting a stranglehold on the Rays offense. It was the perfect formula for the Red Sox to beat the Rays, 4-0, Sunday afternoon, finishing off the three-game sweep of the Rays and extending their win streak to seven games.

Lester went seven innings, giving up four hits and a walk with 12 strikeouts a hit batter and a wild pitch for the win. He threw 122 pitches, 73 for strikes, as he improved to 6-6 lowering his ERA from 3.45 to 3.15. In a stretch from the final out of the third until the last out of the fifth he recorded every out by a strikeout, with a James Loney ground-rule double with one in the fifth breaking up the stretch.

Erik Bedard took the loss, falling to 2-4 with a 4.27 ERA. He went 4 2/3 innings, giving up three runs on five hits and four walks with four strikeouts. He threw 104 pitches, 60 for strikes.

Lester struck out every member of the Rays starting lineup except James Loney at least once. Jerry Sands, who was called up by the Rays just before the game, struck out three times against Lester.
