Kansas City Royals starting pitcher Danny Duffy delivers to a Colorado Rockies batter during the first inning of a baseball game at Kauffman Stadium in Kansas City.

OVERLAND PARK, Kan. — Authorities say Royals pitcher Danny Duffy has been cited for driving under the influence.

The infraction happened Sunday night in the Kansas City suburb of Overland Park. Police spokesman Brian Payne said he could not release further details until the police report is completed, probably sometime Tuesday afternoon. Payne didn't immediately return a phone message from The Associated Press.

The Royals issued a statement saying they were disappointed in Duffy, who was not with the team Sunday because he was in Kansas City for an MRI examination.

"We are still in the early stages of gathering the details, but Danny has always been accountable as a member of this organization and we expect the same accountability from him as the process moves forward," the team said in its statement.

The Royals' No. 1 starter, Duffy has been on the disabled list since Saturday because of a sore left elbow. An MRI exam revealed no structural damage and the Royals hope to have him back this season.
