Welcome to the 2026 edition of Ranking the Rockies, where we take a look back at every player to log playing time for the Rockies in 2026. The purpose of this list is to provide a snapshot of the player in context. The “Ranking” is an organizing principle that’s drawn from Baseball Reference’s WAR (rWAR). It’s not something the staff debated. We’ll begin with the player with the lowest rWAR and end up with the player with the highest.
No. 38, Keegan Thompson (-0.2 rWAR)
Keegan Thompson’s first season with the Rockies may have been short,
but it mirrored his career. It started off on a good note, but didn’t last.
Thompson made his debut on May 23 for the Rockies, who signed the 31-year-old RHP in January after he was waived by the Cincinnati Reds. The third-round pick from the 2017 MLB Draft threw 2.2 scoreless innings in a 5-4 loss to the Arizona Diamondbacks, giving up three hits and two walks with two strikeouts.
Thompson allowed one run on one hit and posted one strikeout against the Giants in the Rockies 8-6 win on May 29.
The next three outings went much worse.
He was hit hard in the following 8.1 innings, being tagged for 10 runs on 15 hits. Thompson struck out eight during the stretch and didn’t walk any; however, by the time his five appearances were done, he had an 8.25 ERA — the worst season in his five-year MLB career.
Thompson’s fifth start came on June 7. By June 9, he was designated for assignment and Cole Carrigg took his spot on the roster.
Thompson cleared waivers and spent the rest of the season with Triple-A Albuquerque where he made 25 appearances, including 15 starts. He posted a 5.28 ERA with two holds, one save, 56 strikeouts, 35 walks and a 2-5 record in 73.1 innings. He also missed two-and-a-half weeks on the IL from the end of August through early September.
Thompson, who was drafted by the Chicago Cubs, made his MLB debut in May of 2021. For two years, he served as a starter and reliever and enjoyed a decent amount of success. In 2021 and 2022, Thompson posted a 3.64 ERA in 61 innings (23 starts) with a 13-8 record and 2.2 rWAR.
Paralleling the end of his 2026 season in Colorado, he spent the next two seasons splitting his time as a reliever for the Cubs and their Triple-A Iowa squad. He made 43 appearances out of the bullpen for the Cubs in 2023 and 2024 with a 3.66 ERA, but just a 0.6 rWAR. By the end of 2024, he declared free agency and was signed by the Reds. He never appeared in the big leagues in 2025, pitching in 33 MiLB games with a 4.50 ERA.
When Thompson signed with the Rockies, he inked a one-year, $1.3 million deal. Thompson’s arsenal includes a four-seamer, a cutter and a sinker, with an occasional sweeper, curve or changeup. His velocity maxes out at about 92 mph, but his known for his ability to pound the strike zone, which the Rockies value under 2026’s new front office and coaching staff. Unfortunately for Keegan, it often resulted in other teams teeing off on him.
In the end, the inconsistency that has plagued Thompson throughout his MLB career continued in 2026.
It makes his future anything but certain come 2027.
