Fast arm and up to 94 mph at PG National! Very athletic and showed a potential plus breaking ball.
At various times, Marshall will show three pitches that can grade as better than average. His fastball often sits at 90-92 mph and has peaked at 94. He shows aptitude for throwing his changeup, an upper-70s offering with good movement. His curveball is his third-best option at this point yet is a plus offering when he throws it with more power in the high 70s. Though Marshall lacks size, he uses a high three-quarters delivery to drive is pitches down in the strike zone. He's athletic and repeats his delivery well.
