MIAMI – The Miami Marlins have announced the signing of right-handed starting pitcher Cal Quantrill to a one-year Major League contract. In a corresponding move, left-handed pitcher Braxton Garrett has been placed on the 60-day injured list following a left elbow UCL revision repair with internal brace surgery.
Quantrill, 30, posted an 8-11 record with a 4.98 ERA (82 ER/148.1 IP) over 29 starts for the Colorado Rockies last season. He led the Rockies in wins and ranked third on the pitching staff in starts, innings pitched, and strikeouts (110). Quantrill pitched at least 5.0 innings in 21 starts, lasting at least 6.0 innings in 12 of those outings and recording a quality start in each. He completed the year with his most starts, innings, and strikeouts since 2022 with Cleveland after making only 19 starts in 2023.
Quantrill has spent most of his Major League career with the Guardians, boasting a 27-15 record with a 3.58 ERA (179 ER/450.1 IP) in 99 games (75 starts) over four seasons. From 2020-22, Quantrill pitched in 44 regular season games (34 starts) without suffering a loss at Progressive Field, going 14-0 with a 2.88 ERA (66 ER/206.0 IP). He joined former New York Yankee Vic Raschi as one of the only players in Major League history to win 14 games without a loss at a single venue.
In 2021, Quantrill led the Guardians’ pitching staff with 149.2 innings pitched and a 2.89 ERA (48 ER/149.2 IP), while his 1.94 ERA in the second half of the season was the lowest in the American League. Quantrill also paced the Guardians’ staff in games started (32) during the 2022 season, setting career highs in innings pitched (186.1), strikeouts (128), and wins (15). His win total was bolstered by 11 consecutive victories to close out the season, helping the Guardians clinch the AL Central title.
Originally from Port Hope, Ontario, Canada, Quantrill was selected eighth overall by the Padres in the 2016 First-Year Player Draft out of Stanford University. He has compiled a 43-34 record, one save, and a 4.07 ERA (325 ER/719.0 IP) in 161 games (123 starts) over six seasons with the San Diego Padres (2019-20), Cleveland Guardians (2020-23), and Colorado Rockies (2024). Cal and his father Paul, a 14-year Major League veteran reliever and former Marlin, join Griffin and Jeff Conine, and Ryan and David Weathers as the third father-and-son duo on the Marlins roster.
