The official diagnosis on Royals OF David DeJesus: Sprained right thumb.
The Royals passed along the official word and also said he would be out for (at least) the rest of the four-game Yankees series, which started tonight.
DeJesus injured his thumb tracking down a long fly ball from Derek Jeter.
DeJesus couldn't make the catch and jammed his hand against the outfield wall causing him to hit the ground in pain. He left the game and went straight to the locker room.
