The A’s announced today they have designated right-hander Tanner Anderson and infielder Corban Joseph for assignment. The moves clear space for their previously-reported additions of Sean Murphy and Sean Manaea.
Oakland acquired Anderson from the Pirates last offseason. The 26 year-old started five MLB games but mostly served as rotation depth at Triple-A Las Vegas, where he pitched to a 6.00 ERA with underwhelming peripherals, even in the context of the environmental challenges he was dealt. He does come with two additional option seasons, so he offers roster flexibility even if his most recent performance has been underwhelming.
The 30 year-old Joseph, meanwhile, got his most extensive big league action (40 plate appearances) this season in Oakland. In his limited big league time, he’s started games at first, second and third base and mashed this year in Las Vegas, but between his age and limited track record, he seems likely to clear waivers.
