The Red Sox offense smacked around Orioles starting pitcher Alex Cobb as Boston cruised past Baltimore 10-3 Saturday at Fenway Park.

The Red Sox jumped on Cobb early, scoring in the first inning on an RBI double to left field from Andrew Benintendi and a two-run homer into the Monster seats by Hanley Ramirez.

A J.D. Martinez solo home run into the right field-bullpen in the third inning put the Red Sox up 4-0.

Benintendi knocked in two runs on a line drive single to right field in the fourth. That was followed by an RBI double to left field by Ramirez, which put the Red Sox up 7-0. Benintendi and Ramirez each went two-for-five at the plate with three RBI's apiece.

Martinez added an RBI single in the sixth inning, and finished batting three-for-five with two RBI's.

Making his Orioles debut, Cobb was roughed up for eight runs -- seven earned -- in 3 2/3 innings. Cobb signed a $57-million, 4-year deal with Baltimore in March after spending the first six years of his MLB career in Tampa Bay.

Hector Velazquez pitched five innings for the Red Sox and gave up two runs on six hits while striking out five. Marcus Walden gave up one run on three hits over three innings, good enough for his first big-league save.

With the win, Boston is off to its best start in team history at 12-2.
