The Mariners claimed reliever Ryan Loutos off waivers from the Nationals, per a team announcement. The move brings Seattle’s 40-man roster count to 38.
Loutos joins the fourth organization of his career. He’s a former undrafted free agent signee of the Cardinals who debuted with St. Louis in 2024. He made three appearances. The Cards designated him for assignment in April and traded him to the Dodgers for cash. Loutos didn’t spend much time in L.A. (though he’ll collect a World Series ring for his brief stop), as he made just two big league appearances. The Dodgers lost him on waivers to the Nats in June.
The 6’5″ righty pitched ten times for the Nationals. He allowed 16 runs (12 earned) with six walks and strikeouts apiece over nine innings. He had a better season in Triple-A, where he combined for 43 2/3 innings of 3.50 ERA ball. Loutos recorded a league average 22.8% strikeout rate while walking a little over 10% of opponents in the minors. He averages 95 MPH on his heater and has a slider and changeup.
There’s minimal cost for the Mariners in using an open roster spot to stash Loutos as bullpen depth. There’s no guarantee he’ll stick on the 40-man all offseason. If he does, he can be sent to Triple-A Tacoma without going on waivers. Loutos still one minor league option remaining.
