Rockies release veteran left-hander

The Colorado Rockies have released veteran lefty Austin Gomber, per a team announcement. (Thomas Harding of MLB.com reported the move just minutes prior to its announcement.) He was reportedly placed on outright waivers earlier this week. Given that he’s now being released, it’s clear he wasn’t claimed. Colorado will give its 40-man spot to lefty reliever Lucas Gilbreath, whose contract has been selected from Triple-A Albuquerque. The Rox also placed righty Dugan Darnell on the 15-day injured list due to inflammation in hi s left hip and recalled righty Angel Chivilli from Triple-A.

Gomber, 31, was the lone remaining player from the Rockies’ return in their trade of Nolan Arenado to the Cardinals. He was only a few weeks from reaching free agency anyhow, as he crossed six years of major league service earlier in the season, but he’ll now head to the open market a bit earlier than previously scheduled.

A shoulder injury kept Gomber on the injured list from Opening Day into mid-June. He’s since made 12 starts and struggled more than he has at any point in his career. Gomber has been a fifth starter over his time with the Rockies, pitching to a middling 5.08 ERA in 544 innings from 2021-24, but he’s been tattooed for a 7.49 earned run average in 57 2/3 innings with the Rockies in 2025.

Though he’s never thrown hard, Gomber’s average fastball this year is sitting at a career-low 89.5 mph. That’s down one mile from last year and down a bit more than two miles per hour over his first season with Colorado back in 2021. His already low strikeout rate has bottomed out at a career-worst 12.5%, and his 7.2% swinging-strike rate is tied (with teammate Antonio Senzatela) for ninth-worst among the 257 pitchers who’ve tossed at least 50 innings in 2025.

Despite Gomber’s subpar results through his four seasons in Denver, the Rockies opted to tender him a contract this past offseason. He’s being paid $6.35M this season, with about $1.26M of that sum yet to be paid out over the final month-plus of the year. The Rockies will remain on the hook for the entirety of that amount, minus the prorated league minimum for any time Gomber may spend on another team’s big league roster.

Gilbreath, 29, posted solid numbers with Colorado in his first two seasons from 2021-22: 85 2/3 innings pitched, 16 holds, one save, 3.78 ERA, 25% strikeout rate (albeit with an ugly 13.2% walk rate). He looked like he’d carved out a role in the Rockies’ bullpen, but a UCL tear during spring training in 2023 wiped out his entire season and limited him to just one big league inning in 2024. The Rockies passed him through waivers earlier this season, and he’s now back in the majors for the first time this year and will look to get back into just hi s second MLB game since the conclusion of the 2022 campaign.

It’s been a tough year for Gilbreath in Albuquerque. Granted, that’s an extremely hitter-friendly setting, but a 6.21 ERA, 11.8% walk rate and 1.91 HR/9 rate can’t solely be blamed on league environment. He’s been a bit better of late (5.29 ERA in his past 17 innings), but the results still aren’t all that encouraging — nor is the fact that a heater that averaged 93.8 mph in 2022 is now sitting 89.8 mph three years and one major surgery later. Be that as it may, he’ll be summoned to the majors to give the Rockies a fresh arm and perhaps to audition for a 2026 spot in the season’s final few weeks.
