Marlins put Walker (quad) on IL, recall Riddle

SAN DIEGO -- The Miami Marlins have placed first baseman Neil Walker on the 10-day injured list with a strained right quad and recalled infielder JT Riddle from Triple-A New Orleans.

The moves were made before Friday night's series opener against the Padres.

Walker pulled up running out a groundout in the sixth inning against San Francisco on Thursday.

He was hitting .295 with four homers and 14 RBI.
