The Rockies announced that they have selected left-hander Carson Palmquist to their roster. Thomas Harding of MLB.com reported yesterday that Palmquist was likely to be promoted and to make his major league debut starting tonight’s game. They also reinstated infielders Ezequiel Tovar, Tyler Freeman and Aaron Schunk from the 10-day injured list. To make room for those four, outfielder Sean Bouchard and right-hander Anthony Molina have been optioned to Triple-A Albuquerque while infielders Owen Miller and Alan Trejo have been designated for assignment.
Palmquist, now 24, was selected by the Rockies in the third round of the 2022 draft. Since then, he has been climbing the minor league ladder, putting up some good strikeout numbers but also giving out a fairly high number of free passes.
Overall, he has 246 1/3 minor league innings under his belt with a 3.91 earned run average. He has punched out 31.1% of opponents but also given out a walk 117 times, an 11.2% clip. He has also plunked 21 batters, only adding to the number of free bases he’s given out.
That includes 70 2/3 Triple-A innings, starting in August of last year and continuing through the present. For the Isotopes, who play in the hitter-friendly Pacific Coast League, Palmquist has a 4.84 ERA, 24.1% strikeout rate and 14.3% walk rate.
Coming into 2025, Baseball America ranked Palmquist as the #8 prospect in the Rockies’ system. They note that the sidearming lefty doesn’t have overpowering stuff, with his fastball generally sitting in the low-90s, but with his angle and extension helping him get results from it. He’s been able to generate a lot of whiffs with his slider while also mixing in a cutter and a changeup. FanGraphs ranked him #6 in the system with a fairly similar report.
Both outlets feel Palmquist has a shot to be a serviceable back-end starter. There’s not much stopping the Rockies from letting him begin that journey now. The team has a dreadful 7-36 record, easily the worst in the majors. Since Ryan Feltner landed on the injured list a couple of weeks ago, they have had a four-man rotation core of Germán Márquez, Kyle Freeland, Antonio Senzatela and Chase Dollander, while also giving spot starts to Bradley Blalock and Tanner Gordon.
Both Blalock and Gordon are currently on optional assignment in the minors. Each of Márquez, Freeland, Senzatela and Dollander has an ERA above 6.00. The Rockies are about to play 13 straight games, starting tonight. Perhaps this will just be a spot start for Palmquist, though he could also get three turns if he stays up for the rest of this 13-game stretch.
Even if Palmquist doesn’t get an extended rotation look right away, there’s a long-term path. Márquez is an impending free agent, as is Austin Gomber, who is currently on the IL. Senzatela and Freeland are both only signed through 2026. Senzatela’s pact has a $14MM club option for 2027 though it’s hard to see that being picked up right now. Freeland can unlock a $17MM player option for 2027 by pitching 170 innings in 2026, though he has only hit that number twice in his career. Even if he’s trending towards hitting it next season, the Rockies would probably be wise to reduce his workload and not allow him to, unless he is having far better results between now and then. In that scenario, he might turn down his option and head to free agency.
Regardless of how those options play out, there should be room for young guys like Dollander, Palmquist and Blalock to take over rotation jobs in the long run, though the difficulties of pitching at Coors Field make that a tricky task even for the most talented pitching prospects.
On the position player side, Tovar, Freeman and Schunk are all back in the infield mix. That squeezes out Trejo and Miller, each of whom are out of minor league options. Trejo returned to the organization last month in a trade with Texas. He hit .175 in 14 games. Miller, acquired in a minor league deal with Milwaukee over the offseason, was promoted around the same time. He went 2-14 over nine contests. Both players figure to land on waivers in the next few days.
