ST. PETERSBURG, Fla. — Dustin Pedroia hit his fourth career grand slam to help Rick Porcello get his major league-leading 22nd win, and the AL East-leading Boston Red Sox beat the Tampa Bay Rays 6-4 Saturday night for their 10th consecutive win.

Boston maintained a 5½-game lead over Toronto for the division title and lowered its magic number for a playoff berth to one.

Pedroia stopped an 0-for-17 skid with a single in the sixth and gave Boston a 6-3 lead with a seventh-inning drive off Danny Farquhar.

Porcello (22-4) gave up three runs, eight hits and struck out nine over 6 1/3 innings.
