Traded to Seattle The Athletics traded Klein to the Mariners on Tuesday in exchange for international slot money.
Impact After the trade, Klein was added to Seattle's 40-man roster. The right-hander was designated for assignment Friday, but 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.

Taken off 40-man roster The Athletics designated Klein for assignment Friday.
Impact 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 30.4 percent strikeout rate at the minor-league level, so he figures to draw some interest via trade or waivers.

Shelved at Triple-A Triple-A Las Vegas placed Klein on its 7-day injured list Aug. 31 with an unspecified injury.
Impact Acquired from the Royals at the trade deadline, Klein initially reported to Oakland and made three appearances for the big club before being optioned to the minors Aug. 17. He gave up three earned runs on six hits and five walks over 5.1 innings across four outings prior to landing on Las Vegas' IL.

Sent to Las Vegas Klein was optioned to Triple-A Las Vegas on Saturday.
Impact Klein gave up five earned runs on two hits and four walks while recording one strikeout in 1.2 innings across three appearances since the Athletics acquired him from the Royals at the deadline as part of the return for Lucas Erceg. The 24-year-old righty walks too many batters (16.3 BB% at Triple-A, 15.8 BB% in the majors) to work in high-leverage situations anytime soon.
