The Athletics traded Klein to the Mariners on Tuesday in exchange for international slot money.
Analysis: After the trade, Klein was added to Seattle's 40-man roster. The right-hander was designated for assignment Friday, but he had the tools to drive interest of other clubs. The Mariners will be the hard thrower's third ball club after beginning his career with the Royals.
Will Klein Taken off 40-man roster
The Athletics designated Klein for assignment Friday.
Analysis: The transaction clears a spot on the 40-man roster for Jose Leclerc, who was signed Friday. Klein, who was acquired from the Royals at the trade deadline as part of the return for Lucas Erceg, allowed nine runs with a 7:6 K:BB over 7.1 innings in his first go-round in the majors in 2024. However, the big righty throws hard and has 30.4 percent strikeout rate at the minor-league level, so he figures to draw some interest via trade or waivers.
