As befits his status as the Red Sox' No. 1 starter, Jon Lester had previously drawn CC Sabathia and David Price as opponents and beaten them both.

On Sunday, when he drew Yu Darvish, the results were different.

Neither Lester nor Darvish factored in the decision, but the Sox lost 4-3 to Texas, giving the Rangers a sweep of the three-game series.

Lester pitched six innings and allowed three runs on five hits. He was good, even if he wasn't as dominant as Darvish, who also gave up three over seven innings while striking out 14.

"I felt good," said Lester. "I felt like I had pretty good stuff. I made two mistakes; against a team like that, in this ballpark, you can't do that."

The two mistakes were both homers -- a solo shot to Mitch Moreland in the third, and then, more critically, a two-run homer to Nelson Cruz in the sixth, which erased what had been a 3-1 lead.

"(I wanted it) in," said Lester. "It was middle-up. The pitch to Moreland, so what, solo homer. But this team is built off momentum. They get a base knock (right before) by (Adrian) Beltre and they got a little bit of momentum going and I let them back in the count.

"He didn't try to do too much with it and put a good swing on it."

Even with Moreland's homer, Lester was efficient through the first three innings, needing just 35 pitches. But over the next three innings, the Rangers made him work and Lester threw 80 pitches from the fourth through the sixth.
