The White Sox announced Friday morning that infielder Jacob Amaya has been designated for assignment. He’ll be the corresponding roster move for Chicago’s previously reported acquisition of reliever Miguel Castro. The Sox also added infielder Vinny Capra, whom they claimed off waivers from the Brewers, to their active roster. Left-hander Jared Shuster was optioned to Triple-A to clear a second roster spot.

Amaya, 26, originally came to the White Sox via waivers last August. He was briefly jettisoned from the 40-man roster in January and claimed by the Orioles. The South Siders claimed Amaya back from Baltimore two weeks later when the O’s tried to pass him through waivers themselves.

Amaya is regarded as a gifted defender but offers little with the bat. He’s appeared in 56 games with the ChiSox and totaled 139 plate appearances but has just a .140/.174/.155 batting line to show for it — including a .097/.119/.113 slash in 68 plate appearances this season. Though he’s yet to provide any offense in the big leagues, Amaya has a more palatable (albeit still below average) .246/.342/.380 batting line in 1219 plate appearances at the Triple-A level.

Because Amaya is out of minor league options, the Sox couldn’t simply send him directly to Triple-A Charlotte. He’d first need to pass through outright waivers for the Sox to be able to assign him to a minor league affiliate. Major League Baseball’s DFA window lasts a week, and the Sox are free to explore trade possibilities or place Amaya during that time. Waivers are a 48-hour process, however, so if they find a trade partner it’d need to happen within the next five days. Given Amaya’s struggles this year, waivers seem likelier, but a team with a short-term need at shortstop could show some interest.
