Red Sox 7, Marlins 5: David Ortiz and Kelly Shoppach swatted two-run homers as host Boston won a slugfest to move back above .500.

Cody Ross added a solo blast in his first game back from the disabled list to help a shaky Clay Buchholz win his fourth consecutive start.

Buchholz (8-2) allowed five runs on nine hits in six innings to beat Miami for the second time in eight days and Alfredo Aceves earned his 17th save as the Red Sox won for the fifth time in six games.

Logan Morrison had a career-high five RBIs - all coming with two outs - on a two-run homer and a pair of doubles off Buchholz, but it wasn't enough to prevent the Marlins from dropping to 2-11 in their last 13 games.

Marlins starter Mark Buehrle (5-8) lost his fourth straight start, giving up six runs on seven hits and three homers in five innings.

After Morrison went deep in the first inning, Ortiz walloped his 17th homer in the bottom of the frame and Shoppach drilled a two-run homer in the second for a 4-2 lead.

Morrison's second double plated two runs in the fifth to tie it at 5-5, but the Red Sox went ahead to stay on Adrian Gonzalez's sacrifice fly in the bottom of the inning before Will Middlebrooks added an RBI double in the sixth.
