BOSTON — Dustin Pedroia drove in three, Drew Pomeranz pitched three-hit ball into the seventh inning and the Boston Red Sox beat the Toronto Blue Jays 5-1 on Wednesday night.

Jays starter Aaron Sanchez left after four innings with what manager John Gibbons described as a recurrence of his blister issues. Sanchez (1-3) gave up five runs, six hits and five walks in four innings. It ended his four-game winning streak against Boston.

Pomeranz (10-4) allowed an unearned run over 6 2/3 innings to win his fourth straight decision and continues to be among Boston's most dependable arms. He hasn't lost since June 11, and the Red Sox are 9-3 in his past 12 starts. His ERA over the stretch is 2.62, dropping it from 5.29 to 3.51 for the season.

Pedroia and Deven Marrero each had two-run singles with two outs in the second inning to provide all the offence the Red Sox needed. Pedroia has six RBIs in the series, which concludes Thursday.
