Baseball-Reference says the NY Giants used Hearn 16 times,all as a starter and the Cardinals used him 6 times as a reliever. If you search for him as a starter, he doesn't show. He shows as a reliever 3 times (Giants only and the two combined). His IP/g is 7.81.
Will I have any problem using him as a starter? I tried him in simulated games and the robo manager pulled him before he finished 5 innings every time.
