Jon Lester outdueled Jake Peavy on Saturday night, lifting the Boston Red Sox to 1-0 win over the Chicago White Sox for their sixth straight win.
Adrian Gonzalez had an RBI single in the fourth as Lester (1-2) picked up his first win of the season. Lester snapped a career-worst streak of losing five straight decisions and going eight starts without a win dating to Sept. 11 of last season. He gave up five hits and one walk, striking out seven.
The Red Sox evened their record at 10-10.
Peavy (3-1) failed in his bid to win a fourth straight start for the first time with the White Sox, but threw a complete game for a second consecutive start for the first time in his career. Peavy hasn't had more than one complete game in a season since 2006, when he was with San Diego.
Peavy shut out Oakland on Monday in his last start, a 4-0 win over the Athletics in which he faced four batters over the minimum. He lowered his ERA to 1.72, limiting Boston to four hits, and struck out six while retiring the last 12 batters he faced.
Franklin Morales and Vicente Padilla held the White Sox scoreless in the eighth. For Morales, it was his 22nd straight scoreless road outing, most ever by a Boston left-hander.
Alfredo Aceves pitched the ninth for his fifth save in seven chances.
Lester had allowed 12 runs over his previous two starts.
Ryan Sweeney hit a bloop double leading off the fourth, the ball falling in after White Sox second baseman Gordon Beckham made a diving attempt for it near the right field line. One batter later, Gonzalez lined a single up the middle to score Sweeney.
The run ended Peavy's string of 17 straight scoreless innings.
By winning the low-scoring contest, the win was a departure from the rest of Boston's streak. The Red Sox scored 44 runs over the first five games of the spree.
Paul Konerko doubled twice and walked for Chicago, and now has six multihit games over his last eight outings.
