The Mariners are going to sign left-hander Josh Fleming to a minor league deal, reports Robert Murray of FanSided. The Republik Sports client also receives an invite to major league spring training.
Fleming, 29 in May, just signed a minor league deal with the Mariners in August. He made 19 appearances for their Triple-A club down the stretch, allowing 4.50 earned runs per nine innings. He didn’t get added to the roster and became a free agent at season’s end, though has now circled back the M’s on a fresh deal.
The southpaw has appeared as a swingman in each of the past five major league seasons, mostly with the Rays but also with the Pirates. He has appeared in 80 major league games, including 25 starts, tossing 254 2/3 innings with a 4.77 ERA. His 14.6% strikeout rate is well below par but his 7.5% walk rate is good and his 58.4% ground ball rate quite strong. Among pitchers with at least 250 innings pitched from 2020 to the present, only five of them have a better grounder rate than Fleming: Clay Holmes, Andre Pallante, Framber Valdez, Emmanuel Clase and Logan Webb.
Fleming’s strikeout rate is far lower than everyone in that group, which has prevented him from posting especially strong results, but he’s been serviceable enough to serve as a solid depth piece. On a minor league deal, there’s no risk for the M’s.
Seattle has a very strong rotation but the depth is a little concerning. Luis Castillo, George Kirby, Logan Gilbert, Bryce Miller and Bryan Woo are an excellent front five but things get flimsy beyond that. There have been some trade rumors surrounding Castillo this winter, which could lead to Emerson Hancock or Jhonathan Díaz moving up to the number five spot. In the bullpen, guys like Matt Brash and Jackson Kowar are working back from Tommy John surgeries, while Gregory Santos spent most of 2024 on the injured list due to arm issues.
Fleming gives the club a bit of depth for both areas without taking up a roster spot. If he gets added at any point, he is out of options but has less than four years of service time, meaning he could be retained into future seasons via arbitration.
