CHICAGO -- Jake Peavy certainly did his part on Saturday night.Chicago's ace allowed just one run while tossing his second straight complete game. Unfortunately, that one blemish was enough to send the offensively-challenged White Sox to their fifth straight loss in a 1-0 defeat to the Red Sox at U.S. Cellular Field. It's the first time in Peavy's career he's completed back-to-back starts. "I'm pleased with the way I performed," Peavy said, "but at the same time, losing's losing. It's tough to get beat, especially on your good day." "For us, Jake's been pitching like that all year," White Sox manager Robin Ventura said. "It's unfair for you to expect that every time he's goes out. He just continues to impress and pitch brilliantly. That's the frustrating part. You get a pitching performance like that and don't take advantage." Peavy was cruising from the get-go, tossing three hitless innings with four strikeouts. But the Red Sox broke through in the fourth when Adrian Gonzalez -- Peavy's former teammate in San Diego -- singled home the lone run, ending Peavy's scoreless streak at 17 innings. "I just have to make a better pitch to Gonzalez there," said Peavy. "That's who he is. You make a mistake to him, he's going to make you pay." "[Peavy] got hurt a couple of years ago and he's back to his old self," Gonzalez said. "Locating pitches and just attacking the strike zone." Red Sox starter Jon Lester was just as brilliant on this night, though, coming up with his best performance on the young season. He allowed five hits and struck out seven in seven shutout innings. "Those games are fun," Lester said. "It's just a battle. I've been on the other end of those. You feel like you do everything you can to put your team in position to win, and the other guy just does a little bit more or you don't get the timely hitting or whatever." The White Sox missed a chance to take the lead in the first inning when Adam Dunn was unable to score from first on Paul Konerko's double after left fielder Cody Ross misplayed the ball in the corner. The White Sox would have a runner in scoring position in the fourth, seventh and eighth innings, but couldn't deliver the clutch hit. "I don't know if [Dunn] is still going to make it for sure," Ventura said. "He saw Ross getting over there in front of it, so he didn't think he was going. "You can look back and see little things that you had opportunities. Tip your hat to Lester for getting out of those situations." Peavy's allowed just two runs over his last three starts with a 0.72 ERA. Still, a loss is a loss for the veteran right-hander, no matter how his pitching line reads. "I'm giving you all I got," he said. "That's a great team across the way. When Jon Lester puts it all together, he's mighty tough. I wish I could've done a little bit more to keep that run off the board, give us a chance."
