Blue Jays 9, Red Sox 7: Edwin Encarnacion belted two home runs, including the go-ahead two-run shot in the seventh, as host Toronto ended a four-game skid.

Trailing 7-6 in a back-and-forth affair, Jose Bautista drew a two-out walk and Encarnacion followed by pulling a fastball from Junichi Tazawa (2-1) over the center-field wall for his ninth of the season. It made a winner out of Steve Delabar (2-1), who had surrendered the lead in the top half of the inning on a David Ortiz bases-loaded double to the gap in right-center field.

Tazawa absorbed the loss in relief of Jon Lester, who surrendered six runs (five earned) on six hits in six innings. Ortiz added a solo home run while Mike Carp and Jonny Gomes also went deep for Boston, which fell short in its quest to earn a club-record 19th win in April.

Already leading 1-0 on a Bautista RBI double, Toronto extended its lead on a bizarre play in the third. With the bases loaded and nobody out, Red Sox catcher Jarrod Saltalamacchia tried to pick off Bautista at first base but his throw sailed into right field, bringing home Brett Lawrie and Rajai Davis.

Ortiz's mammoth home run over the center-field wall put the Red Sox on the board in the fourth, and Carp added a blast to center two batters later to make it 4-2. A Dustin Pedroia run-scoring single trimmed the deficit to one in the fifth, but Encarnacion provided some short-lived breathing room in the bottom of the fifth with a two-run shot into the fifth deck in left.
