June 14: The A’s have released Klobosits, per their transactions log at MLB.com.
June 8: The Athletics announced Wednesday that they’ve designated right-hander Gabe Klobosits for assignment and optioned righty Domingo Tapia to Triple-A Las Vegas. That pair of moves creates space for lefty Jared Koenig, whose contract has been formally selected. A’s skipper Mark Kotsay announced earlier this week that Koenig would be selected from Triple-A to start today’s game.
Acquired on a waiver claim from the Nationals back on April 11, Klobosits has spent the entire season with Las Vegas, where he’s posted an unsightly 7.59 ERA in 10 2/3 frames. The towering 6’8″ righty fanned nearly a quarter of his opponents but also issued a walk to 11.8% of the batters he faced.
Klobosits made his MLB debut with the Nats in 2021, pitching to a 5.56 ERA in a small sample of 11 1/3 innings. He averaged 94.8 mph on his heater during that time and induced chases on pitches outside the strike zone at a gaudy 35.6% clip. The former 36th-round pick also posted a 1.64 ERA with a 28.9% strikeout rate against a respectable 8.8% walk rate in a combined 38 1/3 innings between Double-A and Triple-A last year, so despite his struggles in a brief stint with the A’s, he’s had some success in the upper minors.
Notably, Klobosits does not appear on the minor league injured list but also hasn’t pitched in a game for the Aviators since mid-May. The reason for that layoff isn’t clear. Regardless, the A’s will have a week to trade Klobosits, attempt to pass him through outright waivers (assuming he is in good health; injured players cannot be outrighted) or release him.
