Chase Petty

Petty is the most famous prep pitcher in the country thanks to a fastball that has been up to 102 mph in a bullpen and 101 in a game this spring. He's one of the hardest-throwing high school pitchers ever, up there with Reds righthander Hunter Greene, who went No. 2 overall in 2017 and also touched 102 mph. In games, Petty's fastball has sat 93-96 mph at times and mid-to-upper 90s in other starts. He complements his fastball with an out pitch in his slider, which has tight spin and sharp bite at its best, though at times it has flattened out on him. It's a pitch that flashes plus and shows glimpses of a potential plus-plus pitch in the future. Petty doesn't need his changeup against high school hitters so he rarely throws it, but he has shown feel for that pitch too. Petty's raw stuff suggests considerable upside, but high school righthanders are a risky group as a whole and Petty has several red flags that give teams reservations. He's a good athlete but it's not an easy, fluid delivery, with considerable effort to his arm action and mechanics. His fastball control has also been erratic, with a tendency to yank the ball well out of the strike zone, especially to his glove side. That causes him to fall behind in too many counts and might lead to a high walk rate early in his pro career. Petty's slider misses a lot of bats, though some scouts have said his fastball doesn't lead to as many swings and misses as they would expect given his velocity. He rarely throws his changeup and it's inconsistent, but some scouts think it has above-average potential too. Petty's profile is similar to Lance McCullers from when he was in high school touching triple-digits with a good slider but also had reliever risk and pitchability questions. If Petty proves durable and can rein in his control, his upside is obvious, but his risk factors are ones that teams weigh more heavily now than they did even a few years ago.
