SEATTLE — The Oakland Athletics aren't used to seeing anything go wrong when Grant Balfour's on the mound.
The A's closer hasn't blown a save in his last 36 chances, but he got his first loss in almost a year when he gave up a three-run homer to pinch-hitter Kendrys Morales in the 10th inning of a 6-3 defeat to the Seattle Mariners on Sunday.
Balfour (0-1) came on to start the 10th with the game tied, a situation he's not used to.
"I wasn't expecting the call, I guess," Balfour said. "I guess I'm waiting for us to score to go in and save the game. So I didn't have the right mind frame going in maybe."
After getting a leadoff groundout, Balfour struck out Mike Zunino, only to have him reach first on a wild pitch. Balfour then worked Michael Saunders to a full count before Saunders singled and Zunino advanced to third. Morales then hit the first pitch he saw deep to right-center to end the game.
