The Royals will make a corresponding move before Wednesday night's game against the Chicago White Sox. Manager Trey Hillman said the team tested Ankiel out after the Royals were off Monday before deciding to place him on the disabled list.
Ankiel is hitting .210 in 19 games with three home runs and nine RBIs.
"It is slightly improving when he has to make cuts on it," Hillman said. "Straight lines are OK when he gets long-strided. He's still got a little grabbing in one localized spot. His body hasn't reacted as quickly as we would have liked for it to have. He's done everything right, it just hasn't come as quickly as we thought. We'll DL him and that will leave us a man shy for today."
In another move, the Royals granted Roman Colon his release so Colon can sign with the KIA Tigers of the Korean Baseball Organization. Colon was designated for assignment April 16. He appeared in five games for the Royals this season, allowing four runs in two innings.
