Scouting Report

Scouting grades: Hit: 45 | Power: 55 | Run: 20 | Arm: 50 | Field: 40 | Overall: 40

The great-nephew of Hall of Famer Catfish Hunter, Thach turned down the Giants as an 18th-rounder in 2022 to attend UNC Wilmington. He set the Seahawks' freshman home run record with 15 in 2023 before erasing the overall mark with 27 in '24. His power plays with wood bats as well, as he finished third in the Cape Cod League with eight homers last summer. It disappeared for much of 2025, but the Rockies liked the power potential enough to take him in the eighth round of the Draft.

UNCW's career leader with 54 homers, Thach packs plenty of strength into his 6-foot-4, 225-pound frame and also has enough bat speed to do damage against velocity. He generates high exit velocities and his well-above-average raw power works to all parts of the ballpark, though he rarely uses the opposite field. While he doesn't strike out excessively, teams exploited his tendency to chase pitches this past spring, and he has trouble doing damage against breaking pitches.

Thach has bottom-of-the-scale speed but is a better athlete than that might indicate. He plays a decent first base and has pitched on occasion. His fastball sits around 90 mph and he complements it with a low-80s slider.
