ST. PETERSBURG, Fla. - Dustin Pedroia hit his fourth career grand slam to help Rick Porcello get his major league-leading 22nd win, and the Boston Red Sox clinched a playoff berth by beating the Tampa Bay Rays 6-4 Saturday night for their 10th consecutive win.
Boston maintained a 5 1/2-game lead over Toronto for the division title and ensured no worse than the AL's second wild card. While the Red Sox technically have a magic number of one, the Blue Jays and Baltimore Orioles play each other three times in the season's final week - meaning only one of them can win match Boston's 91 wins.
Among the other wild-card contenders, only Detroit can reach 91 victories.
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. He just missed getting his 12th consecutive start of seven or more innings and three runs or fewer, which would have moved him past Cy Young (1904) and Pedro Martinez (2000) for the longest stretch during the same season in franchise history.
Craig Kimbrel, the fifth Boston reliever, reached 30 saves for the sixth straight season despite allowing Logan Forsythe's solo homer in the ninth.
Brad Miller hit a two-run double in a three-run second that put Tampa Bay up 3-1 and gave him 80 RBIs.
Tampa Bay threatened in the second but failed to score due to two nice defensive plays. Pedroia made a throw from just in front of the outfield grass at second base on Mikie Mahtook's grounder to get Corey Dickerson at the plate. Third baseman Brock Holt made a solid play along the line on Alexei Ramirez's grounder and threw him out at first to end the inning.
