KANSAS CITY -- Royals second baseman Chris Getz, who exited Tuesday night's game with dizziness and an upset stomach, underwent more tests for a possible concussion on Thursday.
"I'm doing better," Getz said.
Getz left the 4-3 win over the Mariners after two innings, shortly after being jarred while making a fielding play. He did not return for the third inning.
