Rupp signed a minor-league contract with the Athletics on Saturday and was assigned to Triple-A Las Vegas. Rupp will provide Oakland with extra depth behind the plate in the high minors while top catching prospect Sean Murphy (knee) works back from a torn meniscus. Oakland has received decent production from Josh Phegley and Nick Hundley at the big-league level this season and could get Chris Herrmann (knee) back from the injured list in a couple weeks, so Rupp may have a tough time earning a promotion to the majors even if he performs well in his initial action with Las Vegas.
Rupp was released by the Tigers on Monday. Rupp is still just 30 years old, and there are many catchers with career slash lines worse than his .234/.298/.407 who have major-league jobs, but he hasn't been able to get into a big-league game since 2017. He hasn't had the best of auditions at the Triple-A level, where he's hit a modest .229/.322/.413 in 107 games with four different organizations since the start of 2018.
Rupp accepted an assignment to Triple-A Toledo on Tuesday. Rupp was the odd man out in the Tigers' catcher contest, falling third behind Grayson Greiner and John Hicks. He'll head to the minors and wait for an injury to open up playing time.
Rupp will not be on the Tigers' Opening Day roster, Jason Beck of MLB.com reports. The Tigers evidently saw no reason to carry a third catcher behind Grayson Greiner and John Hicks. The team will attempt to send Rupp to Triple-A Toledo, though he has the right to refuse an assignment and become a free agent.
Rupp was traded from the Giants to the Tigers for cash considerations Friday, Anthony Fenech of the Detroit Free Press reports. Rupp was in Giants' camp as a non-roster invitee but didn't have a clear path to a roster spot. He'd have to beat out John Hicks for a job in Detroit, though the Tigers could carry three catchers as Hicks is expected to spend time at first base. Rupp was stuck in the minors last season but owns a respectable (for a catcher) .234/.298/.407 line over parts of five seasons in the big leagues.
