Scott Sizemore and Josh Willingham each hit two-run homers during a six-run fourth inning that carried the Athletics to a 15-5 win over the Red Sox last night in Boston, denying Tim Wakefield’s bid for his 200th win.

Dustin Pedroia and David Ortiz hit consecutive homers for Boston.

Wakefield (6-6), making his sixth try to become the 108th pitcher to reach 200 wins, gave up eight runs — four earned — on eight hits.

Gio Gonzalez (11-11) gave up four runs, seven hits, striking out five and walking three in 5 2/3 innings for his second straight win after losing five in a row.

The Red Sox maintaind their one-game lead over the Yankees, who lost to Baltimore, in the A.L. East.

Marlins 6, Phillies 5

In Philadelphia, John Buck hit a grand slam and Greg Dobbs had four hits, including two doubles, to lift the struggling Marlins over the Phillies.

Clay Hensley (2-5) allowed three runs on three hits in 5 2/3 innings to help Florida win for just the fourth time in 21 games and snap a five-game losing streak in Philadelphia.

Roy Oswalt (6-8) matched his career high by allowing 12 hits in 5 2/3 innings.

Indians 2, Royals 1

In Cleveland, Jim Thome went hitless but was warmly welcomed in his homecoming after nearly a decade away and the Indians stopped their slide in the AL Central with a 2-1 win.

Thome went 0 for 4 and struck out twice in his first game back with Cleveland since 2002, when he left as a free agent. The slugger waived a no-trade clause to return to Cleveland and a chance to help the Indians get back to the postseason.

Rays 6, Blue Jays 1

In Toronto, James Shields pitched his major league-leading 10th complete game, Evan Longoria hit a pair of solo home runs, and the Rays beat the Blue Jays.
