The D-backs and free agent righty Thomas Hatch are in agreement on a minor league contract, reports MLBTR’s Anthony Franco. Hatch, a client of Moye Sports Associates, will be in major league camp as a non-roster invitee this spring.
Hatch turned 31 just a couple days after the season ended. He’s pitched in parts of five big league seasons between the Blue Jays, Pirates, Royals and Twins, ending the 2025 campaign with the latter of that quartet. In 103 MLB frames, the former third-round pick (Cubs, 2016) has a 5.24 ERA, 18% strikeout rate, 10.8% walk rate and 46.3% ground-ball rate.
Though he hasn’t found much in the way of consistent big league success, Hatch has been a solid starter in four Triple-A campaigns. He’s pitched 334 innings at the top minor league level and logged a serviceable 4.42 earned run average while punching out 22.3% of his opponents against a tidy 7.5% walk rate. Hatch also has brief experience pitching overseas in Japan’s Nippon Professional Baseball, though he only made five appearances for the Hiroshima Carp during that 2024 stint.
Hatch has split his time in pro ball fairly evenly between starting and relieving. He’ll compete for a job this spring but would presumably be ticketed for a swingman role even if he secured a roster spot. Arizona’s rotation currently includes Merrill Kelly, Ryne Nelson, Brandon Pfaadt, Eduardo Rodriguez and Michael Soroka. Kelly and Soroka signed as free agents this winter. Depth options beyond that group include Yilber Diaz, Cristian Mena, Kohl Drake, Mitch Bratt and Dylan Ray. All five are 25 years old or younger, but no one from that quintet has proven himself in the big leagues yet; the latter three have yet to even make their major league debuts.
