Mariners Acquire Lefty Reliever Josh Simpson from Marlins

The Seattle Mariners have acquired left-handed reliever Josh Simpson, 28, from the Miami Marlins for cash considerations, placing Logan Evans on the 60-day injured list in a corresponding move. Simpson made 31 relief appearances for Miami in 2025, posting a 4-2 record with a 7.34 ERA over 30.2 innings, along with 22 walks and 36 strikeouts. He debuted in MLB on June 21 after recording a 3-1 record with a 3.41 ERA in Triple-A. Simpson, who has a history of injuries, possesses strikeout potential with a strong sweeper and changeup, but has faced command issues.
