Even though he still professes his innocence, A's outfielder Josh Willingham decided to drop the appeal of his one-game suspension and sat out Friday night's game against the Chicago White Sox.

"I dropped the appeal for no reason other than to get it over with," Willingham said.

It probably didn't hurt Willingham's decision that right-handed batters came into the game batting .094 (5 for 53) against White Sox starter Phil Humber. Lefty Ryan Sweeney started in Willingham's place in left field, and might have anyway.

Willingham said there was just too much uncertainty about how the appeal might turn out and when it might be decided.

"It could have been a week, it could have been a month," he said. "I didn't have a clue to begin with what was going to happen. I just got a opinions and none of them were like, 'You're going to win' or 'You're going to lose,' so I just said I'm not going to go through the process."

Willingham drew the suspension after throwing his helmet and bumping home plate umpire Bill Miller in a game at Kansas City last Saturday. He still claims any contact was purely accidental. He added that he will pay an undisclosed fine for throwing his helmet.

With Willingham out, the A's had just three position players available on the bench -- infielder Andy LaRoche, outfielder Conor Jackson and catcher Landon Powell.
