Angels pitcher C.J. Wilson revealed after Monday night's 8-4 win over the Seattle Mariners that he will undergo arthroscopic surgery immediately after the season to remove bone spurs from his elbow, a condition the left-hander said has been bothering him since the All-Star break. "I've been pitching through some little problems the last couple of months," said Wilson, who allowed two earned runs and six hits in 6 1/3 innings, striking out seven and walking five, to improve to 13-10 with a 3.83 earned run average. "A quick visit to Dr. [Lewis] Yocum, a 40-minute procedure, and I'll be out. I should be ready for spring training. I had a similar procedure after 2008 and bounced back pretty well the next couple of years."
