GLENDALE, Ariz. -- The Dodgers moved three pitchers out of camp Monday, optioning Matt Magill and Steven Ames and reassigning non-roster invitee Matt Palmer.
Palmer is injured and will undergo arthroscopic surgery Tuesday on his left knee, which locked up after playing catch Saturday.
Palmer, who turns 34 later this month, had similar surgery on his right knee in 2010, but said he never had a problem with the left one and saw no sign that a problem was coming.
"Out of nowhere," he said. "I do believe this is real minor and I'll be back in three to six weeks. God has a reason for everything. I've just got to fight through it."
