Felix Doubront allowed only three hits while pitching a career-high seven innings, and the Boston Red Sox beat the reeling Miami Marlins 10-2 Wednesday night.
Doubront (7-3), coming off the worst start of his career, retired 16 in a row and took a no-hitter into the sixth inning. He struck out nine and allowed two runs.
The left-hander hadn't pitched more than 6 1-3 innings in his 15 previous career starts.
David Ortiz hit his 15th homer and drove in three runs. Adrian Gonzalez hit a pair of RBI singles, and Scott Podsednik scored twice, drove in a run and had two hits to hike his average to .373.
The Red Sox took two of three games in the series, while the Marlins went 1-8 on their homestand. They were outscored 56-17 while hitting .196, including .127 (8 for 63) with runners in scoring position.
The Marlins' frustration boiled over in the ninth inning with a confrontation involving manager Ozzie Guillen and Heath Bell. Guillen went to the mound to remove the reliever and became angry when Bell lobbied in vain to remain in the game. They then had another testy exchange in the dugout, and coach Joey Cora had to step between them.
With temperatures at about 82 degrees, the teams played with the retractable roof open for the third night in a row, and the balmy weather seemed to suit Doubront fine. The Venezuelan faced an all-right-handed lineup and kept the Marlins on their heels with a fastball clocked at up to 95 mph.
Doubront twice struck out the side. He threw 81 pitches and the Red Sox led 4-0 before the Marlins managed a hit, which came on a homer by Jose Reyes with two outs in the sixth.
Three relievers completed a four-hitter.
Ricky Nolasco (6-5) allowed four runs, three earned, in six innings for Miami. In his past seven starts, he has five losses and an ERA of 5.98.
The Red Sox put the game away with five consecutive hits in a six-run eighth, including four against Randy Choate. He failed to retire a batter, and his ERA rose from 0.48 to 2.41.
Nick Punto pinch-hit for Doubront to start the inning and doubled, then added a two-run single when the Red Sox batted around.
Ortiz hit an opposite-field solo homer into the Marlins' bullpen in the fourth. The Red Sox added two runs in the sixth on an RBI single by Gonzalez and a 400-foot sacrifice fly by Ortiz.
Boston went 7 for 12 with runners in scoring position.
The Marlins trailed 4-1 when Hanley Ramirez singled and Giancarlo Stanton doubled to start the seventh. But they scored only one run when Doubront retired the next three hitters, including Justin Ruggiano on a RBI forceout.
