Thompson was designated for assignment by the Rockies on Wednesday, but he will remain in the organization in Triple-A after clearing waivers. He last saw major-league action in 2024 with the Cubs before spending the entire 2025 campaign with Triple-A Iowa, where he posted a 4.43 ERA, 1.42 WHIP and 85:26 K:BB across 65 innings. Thompson could see some action with Colorado this season should the team require an additional arm out of the bullpen.

Colorado claimed Thompson off waivers in January, but he'll lose his place on the 40-man roster after surrendering 10 runs across 12 innings during spring training. The right-hander could be headed to Triple-A Albuquerque if he passes through waivers unclaimed.
