Gonzales threw an intense 30-pitch bullpen session Thursday, the latest step in his comeback from April 2016 Tommy John surgery, Derrick Goold of the St. Louis Post-Dispatch reports.
The 2013 first-round pick threw all fastballs in the session, splitting his workload over two 15-minute rounds. His velocity represented an increase from that of his previous session, and Gonzales will take things up another notch his next time out after a couple of days of rest. The 25-year-old southpaw owns a career 4-2 record, 4.82 ERA and 1.61 WHIP over 37.1 major league frames and is aiming for a May return to the mound.
