Red Sox's Carson Smith: Placed on 15-day DL

Smith (forearm) was placed on the 15-day DL on Sunday, Jason Mastrodonato of the Boston Herald reports.

Smith is still in the midst of a throwing program after straining his right forearm in spring training. He'll need to resume pitching off a mound and facing hitters before heading out on a rehab assignment in the minor leagues. Once activated from the DL, Smith projects to serve as one of the Red Sox's top setup men.
