Howie Kendrick hit a game-winning sacrifice fly in the 10th inning as the Los Angeles Angels beat the Oakland Athletics 4-3 on Thursday night in a game that was finished under protest.

The Athletics were unhappy with an obstruction call in the ninth inning.

Oakland protested the game after Erick Aybar hit a short chopper up the first-base line to open the inning. He ran into Dan Otero as the pitcher fielded it and bumped into first baseman Brandon Moss.

Home plate umpire Greg Gibson immediately awarded first base to Aybar, prompting a lengthy argument fromBob Melvin. The Angels then loaded the bases with one out, but Kole Calhoun popped up and Mike Trout grounded to third against Cook.

Melvin thinks Aybar went out of the baseline and tried to hit the fielder.

"I thought they would overturn it, based on what we were seeing," the manager said. "It was pretty evident."

Moss, according to the San Francisco Chronicle, said the protest should be upheld because the only person he ran into was Montero, neither of them were in the baseline and Aybar "ran out of it," referring to the baseline, to veer into Montero.

"Obviously, I'm confused by it," Moss told the Chronicle. "Dan actually ran into me, not Aybar. Then when Dan caught the ball, Aybar veered in, I know he veered inside the line. There is video to prove it."

Mike Scioscia disagreed, saying Aybar "had nowhere to go."
