From Baseball America:
Brummel is a 6-foot-4, 190-pound righthander who was pitching in the upper 80s and touching 90-91 in 2023 but took a step forward in the 2024 spring season. He has a quick right arm and throws with plenty of intent—which includes significant head whack and recoil—but has pitched more in the 91-92 mph range and has touched 93-94. He spins the ball well and might get to a plus breaking ball with a pair of different shapes shown this spring. He also has a low-80s changeup. Brummel has extreme reliever risk because of his delivery and well below-average control but his stuff and arm speed are exciting. He’s committed to Indiana.
