BOSTON -- Beset by injuries, Boston's bullpen can't close it out.

Hours after closer Joel Hanrahan announced he would be undergoing season-ending surgery on his right forearm, Junichi Tazawa stepped in and surrendered a game-winning home run to Adam Lind to open the ninth inning as the Red Sox fell 3-2 to the Toronto Blue Jays on Saturday.

With Hanrahan sidelined and Andrew Bailey also on the disabled list, Tazawa (2-2) will serve as Boston's closer until Bailey is able to return from a biceps strain.

"It was a pitch he didn't execute and he paid for it," said Boston catcher David Ross. "Taz has been doing a really great job for us, he's a really good pitcher and he's one of our best.

"That's why they chose to put him in the closer role while the guys are out."

Red Sox manager John Farrell said before the game he was unsure if Bailey would require a rehab stint in the minors, and it remains to be seen whether he will healthy enough to return Tuesday when he's eligible to come off the DL.
