A day after the Royals acquired Sean O'Sullivan from the Angels in exchange for Alberto Callaspo, Kansas City has added O'Sullivan to their active roster. To make room for the right-hander, the team designated Anthony Lerew for assignment, according to a press release.
Lerew started six games for the Royals this year, compiling a 3.63 ERA in his first three starts before getting hit hard (18.00 ERA) in his next three. Lerew's 26.1 IP represent a career high for the former Brave, who was ranked as a top-100 prospect by Baseball America in both 2005 and 2006.
This is the second time this season that the Royals have designated the 27-year-old for assignment.
