Carlson (hamstring) had his rehab assignment transferred to Triple-A Memphis on Tuesday, John Denton of MLB.com reports.

EDGE Analysis

Carlson played in three games at Double-A Springfield over the weekend and went 0-for-7 with a walk and a strikeout. It's possible that the 23-year-old rejoins the Cardinals during their current road trip in Tampa Bay, but he'll require at least one rehab game with the Triple-A club prior to returning from the injured list.
