Garcia was placed on the 10-day injured list Monday with a lumbar spine muscle spasm.
Garcia apparently picked up the issue during his outing against the Orioles on Sunday, during which he issued two walks and allowed a hit in a scoreless inning of relief. It's unclear how long the issue will keep Garcia sidelined at this point; he'll be eligible to return May 23, should he prove ready. Taylor Cole was recalled from Triple-A Salt Lake in a corresponding move.
