Sardinas is battling a tight calf muscle and won't play in Friday's game, the Tacoma News-Tribune's Bob Dutton reports.
It sounds like a very minor issue, as Dutton reports that Sardinas should be back in action Saturday. Sardinas can play both middle infield spots well, and can also play third base in a pinch, which is giving him the leg up on the competition to break camp as the Mariners' utility infielder.
