PHILADELPHIA -- Lucas Duda was placed on the 15-day DL with a left intercostal strain on Saturday, and the Mets called up infielder Zach Lutz.
After complaining of discomfort following Friday night's victory over the Phillies, Duda returned to New York Saturday morning to undergo an MRI on his left side.
Other than saying he didn't believe Duda suffered the injury sliding under Carlos Ruiz's tag for a run in the sixth inning, Mets manager Terry Collins said he did not know how Duda was hurt. But Duda was in enough pain to warrant a medical evaluation.
"Similar situation that we had with Justin Turner," said Collins. "These things can get bad."
Turner was placed on the DL on Tuesday with an intercostal strain.
With Duda out, Collins moved Daniel Murphy to first base on Saturday and inserted Jordany Valdespin at second.
"Today, [Jonathan Pettibone] is pitching, lefties are hitting him pretty good, so I wanted to get Valdespin in there and Murph at first," Collins said.
