The St. Louis Cardinals placed right fielder Jose Martinez on the 10-day injured list with an AC sprain in his right shoulder.
Martinez suffered the injury over the weekend when he ran into the outfield wall after tracking down a fly ball. He's unlikely to return until September. The Cardinals called up outfield prospect Randy Arozarena from Triple-A Memphis in a corresponding roster move.
Martinez is hitting .266/.336/.401 with 10 home runs and 40 RBI in 348 plate appearances (110 games) for the Cardinals this season.
