On the bump, this righty has an effective 3-pitch arsenal in which to attack hitters with. He works to a controlled balance point, has smooth separation with good glove side lead and repeats his delivery well. FB ranges from 79-83 mph as he commands it to both sides of the plate. Changeup has some sink as he works to keep it down in the zone. Slider has 10/4 shape showing to be a solid 'K' pitch. As a hitter, this righty shows a tall/open stance getting his hands back into a strong load/launch position. He takes an aggressive hack, barrels the ball up and drives it with some pull-side pop. McArthur will challenge hitters and compete every time that he toes the rubber.
