BRADENTON, Fla. — Pedro Alvarez and Russell Martin hit two-run homers off Brandon Workman, who started in place of injured Jake Peavy, and the Pittsburgh Pirates beat the Boston Red Sox 7-6 Monday.

Pittsburgh leadoff batter Starling Marte reached on an infield single in the first that stopped an 0-for-9 start, and Alvarez homered to right off Workman with two outs. Marte singled in the third, and Martin followed with a drive to left, his second homer in two days.

Workman gave up five runs and five hits in 2 1-3 innings in place of Peavy, the right-hander who accidentally cut his left index finger with a fishing knife last weekend.

Pirates starter Francisco Liriano struck out three and walked one in two hitless innings.

Mike Carp, trying to win a bench job with the Red Sox, hit a two-run homer against Bryan Morris in the eighth.

Liriano zipped through his two innings on just 25 pitches. After giving way to Edinson Volquez, Liriano threw 10 more in the bullpen before calling it a day. “I felt a lot better about my fastball command today,” said Liriano, who’s made two starts. “The sinker was a lot better.”

Pirates first baseman Gaby Sanchez has not played since Friday, when he hurt his right knee while sliding into third base. Tests showed no structural damage, and Sanchez took some swings in a batting cage Monday.

Travis Snider made his first start in the outfield this spring training. Snider had offseason foot surgery and sliced his left hand in a kitchen accident a few days before reporting to camp. He found out via Twitter about Peavy’s injury.

“I heard that I’m not the only guy who had issues with a knife this spring,” Snider said. “We’ve got to come up with some kind of glove or something. Freak things happen.”
