KANSAS CITY, Mo. -- The Royals placed right-hander Chien-Ming Wang on the disabled list with biceps tendinitis and made a series of roster moves to shore up their taxed bullpen before Wednesday night's game against the Yankees.
Colon is likely to return when rosters are allowed to expand Thursday.
The Royals used five relievers in their rain-delayed, extra-inning loss to New York on Tuesday night. Wang tossed two scoreless innings in the game.
Alexander is joining the Royals for the second time this season and threw a scoreless inning against the Yankees in his big league debut. Pounders is joining the club for the third time this season.
