Jason Schmidt will have arthroscopic surgery on his right shoulder on Wednesday to clean up scar tissue that was preventing him from getting over the top enough in his delivery and also to repair “arthritic changes in the AC joint.” He will begin rehabbing several days after the surgery and resume throwing within six weeks. More importantly, he is expected to be ready by the start of spring training, which already puts him ahead of where he was at this point a year ago. … Jeff Kent is NOT traveling with the team, and no, it isn’t because no one wants him around. It’s because Dr. Neal ElAttrache didn’t want him traveling so soon after the knee surgery. He is back in Los Angeles. Torre said there is a chance he could join the club at some point on the trip.
