The Mariners have signed left-hander Josh Fleming to a minor league deal and assigned him to Triple-A Tacoma, as relayed by Tacoma Rainiers broadcast Mike Curto on X (link). Fleming elected free agency on the day of the trade deadline after being designated for assignment by the Pirates the week prior.
Fleming, 28, was a fifth-round pick by the Rays in the 2017 draft and spent his entire career in Tampa prior to the 2024 season. The southpaw made his big league debut back in 2020 and enjoyed a solid rookie season with a 2.78 ERA and 4.40 FIP in seven appearances, including five starts, that totaled 32 1/3 innings of work. Fleming struck out just 19.2% of opponents in that first season as a big leaguer but made up for that with an eye-popping 63.7% ground ball rate. Those strong results led the Rays to offer Fleming an expanded role the following year as he posted a career-best 104 1/3 innings of work in 2021. Unfortunately, the lefty struggled with the larger role and posted a lackluster 5.09 ERA, though it’s worth noting that his 4.27 FIP and 4.36 xFIP both indicate that he pitched better than that top-level run prevention number might otherwise suggest.
After his lackluster 2021 season, Fleming saw his role in Tampa reduced somewhat as he pitched just 35 innings for the big league club in 2022 followed by 51 2/3 innings of work in 2023. Once again splitting time between the bullpen and starting rotation, Fleming pitched to a combined 5.40 ERA with a 5.16 FIP, a 13.8% strikeout rate, and a 7.9% walk rate. He continued to generate grounders at an impressive 61.4% clip in those years until his 2023 season ended early due to a bout of elbow inflammation. The combination of injury concerns and ineffectiveness led the Rays to designate Fleming for assignment, and while he was snapped up off the waiver wire by the Phillies the lefty became a free agent not long afterwards when Philadelphia non-tendered him.
The southpaw ended up remaining in Pennsylvania despite that non-tender, however, as he eventually signed with the Pirates on a split contract back in February. Fleming made the club’s Opening Day roster out of Spring Training and pitched fairly well for Pittsburgh over the first month of the season. Things took a sharp turn for the worse in May, however, as Fleming allowed nine runs (eight earned) in just three innings of work across four appearances before eventually being outrighted off the club’s roster. He remained with the Pirates in the minors and eventually returned to the roster in mid-June. He pitched well for the club following his return with a 1.46 ERA in 12 1/3 innings of work, though he did so with questionable peripherals as he walked more batters (five) than he struck out (four). That led the Pirates to DFA him once again, though this time he decided to return to free agency rather than remain in the minor leagues with Pittsburgh.
Now, Fleming will join a Mariners organization that currently has just one left-handed pitcher (reliever Tayler Saucedo) on the active roster. Gabe Speier and Jhonathan Diaz are both lefty options in the minors already on the 40-man roster, though each has struggled at the big league level this year. That could leave a clear shot at a big league job for Fleming if he can impress Mariners brass with his performance at the Triple-A level, where he’ll have to contend with the inflated offensive environment of the Pacific Coast League.
Well, they’ve needed a LH reliever for a while now. I don’t know that it’s this one, but they’ve signed worse and, with their mammoth ballpark, have turned their careers around. Just don’t walk anyone. That’s the key to success at T-Mobile.
