Mitchell’s four-seamer displayed excellent arm-side run despite subpar vertical movement, and it topped out at 96 mph. It managed just a 4.4% whiff rate, though, leading to a .304 average and .514 slugging percentage against the pitch.
The curveball didn’t elicit the chase rate (22.6%) or the whiff rate (8%) that you generally like to see from a heavily featured breaking ball. It did hold opponents to a .232 average, but it gave up a lot of hard contact, with a .393 slugging percentage against it.
Mitchell’s curveball was a true worm-burner, generating grounders at an excellent 66.7% rate. It still managed to allow plenty of damage, though, surrendering a .309 average and .473 slugging percentage despite a relatively normal .306 BABIP.
The changeup, though hardly thrown, had good arm-side run and average drop to it. It didn’t elicit hardly any whiffs or chases out of the zone, though, giving up an absurdly high 95% contact rate.
