ST. PETERSBURG, Fla. — Kansas City Royals right-hander Sidney Ponson has been designated for assignment.

Royals manager Trey Hillman made the announcement before Sunday's game against Tampa Bay. Ponson went 1-7 with a 7.36 ERA in 14 games, including nine starts, this season.

Kansas City plans to bring up right-hander Kyle Davies from Triple-A Omaha to start Wednesday's game with Seattle.
