Thinking ahead to a possible return for his 22nd season, Giants slugger Barry Bonds told MLB.com on Wednesday night that he's considering having the bone chips removed from his problematic left elbow as soon as this season ends if, as expected, he decides to return next year. Bonds, who said earlier in the season that he would retire if he had to undergo any more surgery on his 42-year-old body, said he's changed his opinion because the arthroscopic procedure would be quick and unobtrusive. Bonds, whose ninth-inning homer went for naught in a 9-8 loss to the Rockies at AT&T Park, now has 24 on the season and 732 in his career -- one homer behind Hank Aaron's National League record of 733 and 23 shy of the Hammer's all-time mark of 755.
