Gonzales (elbow) is ready to join Triple-A Memphis' starting rotation, Derrick Goold of the St. Louis Post-Dispatch reports.
Gonzales has been throwing regularly in extended spring training for multiple weeks without setbacks, and allowed one earned run on two hits over six innings while recording seven strikeouts on May 7 for High-A Palm Beach against Lakeland. The 25-year-old southpaw last pitched in the majors for the Cardinals in 2015, making one start and compiling a 13.50 ERA over 2.2 innings. He's projected to be in line for multiple rehab appearances before his next step is determined.
