The Chicago White Sox reinstated infielder Chase Meidroth from the 10-day injured list and designated infielder Jacob Amaya for assignment ahead of Friday's series opener against the Kansas City Royals.

Meidroth, 24, had been sidelined since Aug. 7, retroactive to Aug. 4, with a right thumb contusion sustained when he was hit by a pitch from Philadelphia's Taijuan Walker on July 30. The rookie is batting .252 with a .330 on-base percentage and .319 slugging percentage in 84 games this season, with 12 doubles, three home runs, 15 RBIs, 36 runs scored and 11 stolen bases.

Amaya, 26, has appeared in 37 games for Chicago across two stints this season, hitting .106 with eight RBIs and seven runs scored. He has played primarily in the infield.

The White Sox and Royals open a three-game set in Kansas City on Friday night.
