General manager Jerry Dipoto made his third trade in four days on Saturday, adding some relief pitching depth to the Mariners’ 40-man roster.
Seattle acquired right-hander Nick Rumbelow from the Yankees in exchange for minor league pitchers JP Sears and Juan Then.
“Nick is another young, power-arm reliever who provides us with present flexibility and future impact,” Dipoto said.
Rumbelow, 26, spent the entire 2017 season in the Yankees minor league system, splitting time between Class AA Trenton and Class AAA Scranton/Wilkes-Barre. He posted a combined 5-1 record with six saves and a 1.12 ERA in 25 relief appearances.
