Age At Draft: 19
Heuer is an extra-large righthander with a 6-foot-4, 230-pound frame. He throws from a short and compact arm action and three-quarter slot with plenty of arm strength and an in-line finish to the plate. He has a solid fastball that sat around 91-92 mph during 2022 and touched 95 mph at peak, and this spring has been up to 96-97. He previously threw a mid-70s curveball as his go-to breaking ball but during the offseason he began to experiment more with a harder slider—though both iterations of the breaking ball need continued development. He will also mix in a firm, upper-80s changeup that has a bit of fading life. Heuer pitched in the 92-95 mph range at the MLB Draft Combine in June, and he missed a few bats with his fastball, though he continued to show a below-average breaking ball that needs more touch and feel and sharper breaking action. Heuer is on the older end for the class and turns 19 right before the draft. He’s committed to Texas Tech.

Track Record: Heuer was homeschooled but made his way through the showcase circuit and was drafted by Cleveland in the 16th round in 2023. When he wasn’t on the mound, Heuer found time to raise an ewe named Oakley who won grand champion at the 2022 Georgia Junior National Livestock Show. Heuer spent the next two seasons at Texas Tech before the Yankees drafted him in the eighth round. He signed for $400,000, nearly double the recommended slot value. He did not pitch after signing.
Scouting Report: In college, Heuer worked with a full complement of four pitches, led by a fastball that peaked at 97 mph and backed by a changeup and slider in the mid 80s and a curveball in the high 70s. Heuer’s heater worked well when located up in the zone, where it has the kind of life and velocity to zoom past bats. His slider alternated between hard, sweeping break and downer action and has the chance to be an average pitch. Heuer’s changeup has fade and depth away from lefties and could be an average offering as well. His curveball has downer break, but needs more power behind it before it can be much more than a wrinkle against lefthanders or a strike-stealer. Heuer is big and physical and utilizes a delivery with a short, compact action and crossfire finish.
The Future: Heuer’s first stop as a pro could be at High-A Hudson Valley. He’s already cleaned up his body a bit since joining the Yankees and has the makings of a powerful back-end starter.
