Tyler Holton

If Holton were righthanded, there's a chance he isn't on this list at all. Holton throws a well below-average fastball that sits in the mid-80s and tops out at 89 mph, and he has thrown just 4.2 innings this spring after tearing his UCL in February. Because he's left-handed, however, teams will more easily overlook his lack of pure stuff. If healthy, he would have ranked among the top 200 prospects in the draft class because of an impressive resume in the Atlantic Coast Conference. Holton was named first team all-ACC in 2017 and was a second team All-American after posting a 2.34 ERA in 119 innings with 144 strikeouts and 33 walks. Holton was also the best starter for USA Baseball's Collegiate National Team in the summer of 2017, when he posted a 0.69 ERA over in 13 innings with 14 strikeouts and just two walks. Without an average fastball, Holton excels because of his ability to effectively spot pitches in and out of the zone. He also has a plus changeup and a curveball that was showing improvement over the summer. His changeup is his only plus offering, but each of his pitches will play down at the next level because no professional hitter will be challenged by his fastball. There is a professional precedent in Brewers lefthander Brent Suter–who averages 86 mph with his fastball--and Holton has been compared to him at times. Suter is three inches taller, however, and there are more medical questions with Holton as well.
