SEATTLE -- With his team mathematically eliminated from the playoffs, ensuring that Monday night would indeed be his final start of the 2012 season, Angels starter C.J. Wilson revealed that he had been pitching with bone spurs in his left pitching elbow for "the last couple of months" and was set to undergo offseason arthroscopic surgery.

Wilson, who gave up three runs (two earned) in 6 1/3 innings in a win at Safeco Field, had the same problem as a reliever in 2008, prompting him to miss the final two months of his season with the Rangers.

"I bounced back pretty well the last couple of years after that," Wilson said, "so I'm looking at that with a lot of optimism."

Wilson said he already has a date in mind for the surgery. And though he wouldn't reveal it, he will get it done as soon as possible after the season and doesn't see any reason why he won't be ready for Spring Training.

"I tried to make a million adjustments to get around it, to the point where now I'm standing on the first-base side, trying to get an angle because I can't throw sinkers anymore because my arm doesn't work right," Wilson said. "But you're paid to go out there and play."

Wilson believes the elbow problems began in the second half, which would make sense given his numbers.

The 31-year-old left-hander went 9-5 with a 2.43 ERA in 18 first-half starts en route to making his second straight All-Star team. In the second half, though, he finished 4-5 with a 5.54 ERA.

"It's one of those things where you push yourself through anything because your job is to go out there and pitch," said Wilson, who finished the season 13-10 with a 3.83 ERA. "The coaching staff and the training staff have been really great to help me to try to come up with adjustments and try to figure out if there's anything we can do. But bone's not muscle, so there's really one way to get it taken care of."

Worth noting

• Right fielder Torii Hunter left Monday's 8-4 win over the Mariners in the seventh inning because he was feeling light-headed. Hunter said he was probably dehydrated because his muscles were cramping up but felt better after the game.
