Lilly started the season on the DL after undergoing shoulder surgery last season, so the injury is new. Lilly joins fellow Dodgers starters Zack Greinke, Chad Billingsley and Chris Capuano on the DL.
The veteran southpaw made two starts for Los Angeles this season before returning to the disabled list. Lilly looked effective in his first start against the New York Mets, striking out seven hitters in five innings, but struggled against the Colorado Rockies. Lilly was only able to throw three innings in his second outing, surrendering five runs on eight hits.
The Dodgers activated Clayton Kershaw off the bereavement list to take Lilly's spot on the 25-man roster. Los Angeles placed Kershaw on the bereavement list on Monday after his father passed away in Texas. Kershaw is expected to start Friday against San Francisco Giants.
Matt Magill will start in place of Lilly on Saturday. Magill made his major-league debut on April 27 against the Milwaukee Brewers, and pitched effectively in his first start. The 23 year-old tossed 6.2 innings, allowing two runs on four hits while striking out seven.
