14. LHP Antoine Kelly
20-year old Antoine Kelly was a great pitching addition in the Brewers’ prospects. A second round pick in 2019, Kelly has a powerful fastball that’s in the high 90’s and he’s still working to improve his slider and changeup.
Kelly is a major project, and the Brewers knew that when they drafted him. They took a safer pitching prospect in Ethan Small in the first round, so they felt comfortable taking a high-risk, high-reward pitcher like Kelly in the second. Kelly is a fireballer that lacks control of his pitches at the moment and will need to develop a second above-average pitch if he’s going to be an impactful big leaguer someday.
It’s a rarity to find lefties that have a fastball nearing 100 MPH, especially for someone being so young and talented. He got the most mound time with the AZL Brewers Gold where he pitched 28.2 innings and posted a 1.26 ERA, .208 opponent AVG, and a 0.91 WHIP. He also played for the Wisconsin Timber Rattlers, but that time was very short as he was assigned to the Timber Rattlers on August 29th of 2019, and the next day he was assigned back to AZL Brewers Gold.
In his minors career, his overall ERA is a 2.84 which is pretty impressive even though it’s a small sample size. With him being just 20 years old, Antoine Kelly does have a lot of potential stored in him.
The Brewers could try to be aggressive with Kelly and put him in Low-A Wisconsin to start the 2020 season, but he’s likely going to spend some time with the Rookie-Advanced Rocky Mountain Vibes.
In all likelihood, Kelly is ticketed for the bullpen if he were to make the big leagues. If he can put it all together, he could be Josh Hader-level dominant. Standing at 6’6″ and 205 pounds, the left-hander Kelly has rare potential. If the Brewers can continue to harness that potential, Kelly will rise up these rankings in the future. For now, he’s a long ways from the big leagues and lands at No. 14 on our list.
