The Mariners and veteran left-hander Drew Pomeranz are in agreement on a minor league deal, as previously reported by Aram Leighton of Just Baseball. The deal presumably includes an invite to major league Spring Training.
Pomeranz, 36, is a veteran of 11 MLB seasons but hasn’t throw a pitch in the majors since 2021. The lefty was generally a solid player who swung between the back of the rotation and bullpen in the early part of his career, often garnering solid results in relief but lackluster numbers in the rotation. Across the first eight seasons of his MLB career, Pomeranz pitched to a 3.92 ERA (110 ERA+) with a 4.14 FIP in 710 innings of work split between 122 starts and 74 relief appearances. The start of the 2019 season was more of the same for Pomeranz, as he struggled in a swing role with the Giants. He posted a 5.68 ERA ERA with a 5.24 FIP in 77 2/3 innings of work.
Those lackluster numbers led San Francisco to deal the lefty to Milwaukee at that year’s trade deadline, and Milwaukee decided to move Pomeranz to the bullpen full-time, converting him into a high leverage relief arm. The lefty looked like a totally different player down the stretch in 2019, dominating to the tune of a 2.39 ERA with a 2.68 FIP with an eye-popping 45% strikeout rate. That stellar performance earned Pomeranz plenty of interest in free agency that winter, and prior to the 2020 season he signed with the Padres on a four-year deal worth $34MM that ran through the 2020-23 seasons. Pomeranz continued to dominate when healthy enough to take the mound for San Diego, with an incredible 1.62 ERA and 2.75 FIP to go with a 33.7% strikeout rate during the life of that contract.
Unfortunately for Pomeranz, however, he managed just 44 1/3 innings of work over the life of the contract due to shoulder, forearm, and elbow injuries. After not pitching in the majors during the 2022 or ’23 seasons, Pomeranz returned to the free agent market and caught on with the Angels and Dodgers on minor league deals but was unable to crack either L.A. roster. Eventually he earned a big league opportunity with the Giants in May, but lasted just a few days on the club’s roster before being designated for assignment without making an appearance. In total, he made just eight appearances at Triple-A for the Dodgers this past season, struggling to a 6.00 ERA but flashing an excellent 37.8% strikeout rate.
That big strikeout stuff clearly caught the attention of the Mariners, who have now picked him up as a no-risk flier who could still contribute to the club’s late-inning mix if he can finally get healthy enough to make it back to the majors. The Mariners have an impressive bullpen mix that includes Andres Munoz, Matt Brash, Collin Snider, and Gregory Santos but lacks a true back-end option from the left-hand side.
