Royals place RHP O'Sullivan on DL

The Royals have put right-hander Sean O'Sullivan on the 15-day disabled list with biceps tendinitis and recalled Jesse Chavez from Triple-A Omaha.

The team announced the moves Friday before its game against the Minnesota Twins.

O'Sullivan gave up seven runs on eight hits, two walks, a hit batter and a wild pitch in 2 2-3 innings in a loss Thursday to the Twins. He went 0-3 with a 13.25 ERA in his past four starts and was 2-5 overall with a 6.92 ERA in 11 outings, including nine starts.

He is the third Royals starter on the disabled list, joining left-hander Bruce Chen and right-hander Kyle Davies.

Chavez was 2-3 with five saves and a 4.94 ERA in 19 games for Omaha. He will go to the bullpen.
