Pitching
He keeps the ball down and gets a lot of groundballs. Karoll can get into trouble with walks, and there's concern about him being able to maintain his stuff over the whole season. His fastball gets into the high 80s, but it's the sink that makes the pitch effective. He has an above-average changeup and the ability to throw from a variety of arm angles. He attacks lefties and righties with similar success.
Defense & Hitting
Though he lacks a good pickoff move, he checks the running game with a compact stretch delivery. He isn't especially quick off the mound but generally fields his position adequately. Karoll is a surpisingly good hitting pitcher. And I'm not sure you can say this about a pitcher, but Karoll has some pop in his swing.
2025 Outlook
I can't say I know what The Victoria Islanders were doing locking this guy up to a long term contract. A questionable call at best. AA isn't the right place for Karoll. Expect the Victoria Islanders to send him down for some minor retooling. I just don't know if The Victoria Islanders are ever going to get what they expect out of him.
