David Ortiz homered to start a six-run inning, then added a two-run single to finish it Tuesday night and the Boston Red Sox beat the Florida Marlins 8-2.

Tim Wakefield (9-3) allowed two runs in six innings to improve to 6-0 at Fenway Park this season.

Chris Volstad (4-7) allowed nine hits and a career-high eight runs before he was chased in the fourth, when the Red Sox sent 11 batters to the plate. It was his fourth consecutive loss.

Ortiz, who did not homer in the first six weeks of the season, now has five for the year – four of them in the last nine games. His batting average is back up to .210 – still 73 points below his career average, but at least not below the Mendoza line, .200, where he stayed for most of the last month.

Ortiz homered into the Marlins bullpen to lead off the fourth, then came up again with the bases loaded and two outs and singled up to make it 8-1.

Chris Coghlan, who was 7-for-14 over weekend, went 2-for-4 and drove in both runs for Florida, which swept Toronto over the weekend, but failed to reach .500 for the first time since May 13.
