BOSTON – Jake Peavy pitched seven strong innings against his former team, Jacoby Ellsbury had three hits, and the Boston Red Sox beat the Chicago White Sox 7-2 on Saturday night for their sixth win in seven games.

Ellsbury also scored twice and drove in a run for the AL East-leaders. David Ortiz, who snapped an 0-for-23 stretch with a two-run single in Friday’s win, went 2 for 4 with a walk and an RBI in Boston’s 15-hit attack.

Acquired in a three-team, seven-player deal on July 30 that sent Boston infielder Jose Iglesias to Detroit, Peavy spent four seasons with the White Sox. The 32-year old right-hander went 36-29 after being picked up in a trade from San Diego on July 31, 2009.

Chicago, last in the AL Central, had won 10 of 12 before dropping the first two of a three-game series against Boston.

Peavy (11-5) allowed two runs and five singles in his sixth start for the Red Sox. He struck out four and walked one while throwing 109 pitches.

Boston broke open a tie game with three runs in the fourth against John Danks (4-11), and then scored again in the fifth.

Ellsbury’s tiebreaking ground-rule double gave the Red Sox a 3-2 lead. Dustin Pedroia then drove in run with a groundout before Ortiz lined an RBI single to left.

Rookie Xander Bogaerts, one of the top prospects in baseball, added an RBI single in the fifth that made it 6-2.

Danks gave up six runs, five earned, and 11 hits over five innings. He had won his previous two starts, allowing only two runs in 14 innings.

The Red Sox had grabbed a 1-0 lead in the first on Mike Napoli’s RBI single. Chicago tied it on Alejandro De Aza’s run-scoring groundout.

Jonny Gomes doubled home a run in the third, but the White Sox tied it again on Avisail Garcia’s RBI single.

THE RED SOX have acquired infielder John McDonald from the Philadelphia Phillies for minor league right-hander Nefi Ogando.

McDonald adds depth all over the infield and gives Boston an experienced glove for the stretch drive. The AL East leaders announced the deal Saturday night during a game against the Chicago White Sox.

Because the move was made by the end of August, McDonald would be eligible to play for Boston in the postseason.

The 38-year-old McDonald has spent 15 years in the majors. He has played for Pittsburgh, Cleveland and Philadelphia this season, hitting .098 with a homer and four RBI in 45 games.

The 24-year-old Ogando was 2-3 with a 4.09 ERA and three saves for Class-A Salem this season. He made 33 relief appearances covering 55 innings.

The Phillies also sent cash to Boston as part of the deal.
