Justin Turner left Wednesday's game with a strained left calf. As though the Mets don't already have enough infielders to worry about. Turner is the latest addition to a list that already includes second baseman Daniel Murphy and third baseman David Wright. The 28-year-old had only recently recovered from a sprained ankle that cost him some games earlier this spring. The Mets infield has the makings of a M.A.S.H. unit come Opening Day.
