ANAHEIM, Calif. -

Josh Donaldson got off to such a hot start, he was being mentioned as an early-season candidate to make a run at the American League MVP award.

Though the Oakland A's third baseman still has impressive numbers overall, he is slumping at the plate and in the field.

Donaldson went 0-for-6 Tuesday in Oakland's 2-1, 14-inning loss to the Los Angeles Angels, and he is hitting just .111 (4-for-36) through eight games on the current road trip.

He also is going through a tough patch on defense. Donaldson committed three errors in Monday's game. He became the fourth Oakland third baseman to make at least three errors in a game, and the first since Marco Scutaro set the club record of four in 2007.

Donaldson was charged with another error Tuesday -- all four in the series coming on errant throws. He has committed an American League-leading 13 errors on the season.

As for MVP discussion, Donaldson said he would prefer to let his play on the field speak for him.

"I try not to think about it too much," he said. "My big thing is trying to help the team win, focusing on the approach to the game that is going to help me be successful and help the team win. All of that takes care of everything else. If people want to throw me in that category, that's great. You don't get put in that category if you're not doing the right things."
