Cardinals' Drew Rom: Nursing biceps issue

Cardinals manager Oliver Marmol said Thursday that Rom has taken a step back from throwing recently due to a left biceps issue, Lynn Worthy of the St. Louis Post-Dispatch reports.

He hasn't been fully shut down, but the injury helps explain why Rom hasn't made a Grapefruit League appearance in nearly a week. Once healthy, the left-hander is slated to open the season in Triple-A Memphis' rotation.
