6/16/23
Standing at an athletic 5-foot-10, 147-pounds, Ackerman was dominant in his start on Friday evening. Out of an easy and clean delivery, Ackerman ran his fastball up to 83 mph and sat in the 80-82 mph range throughout his 3.2 innings of work. He also was able to spin in a breaking ball with late downer bite that generated plenty of whiffs, and projects as an out-pitch in the future. He eventually struck out seven of the 11 batters he faced enroute to the win.
