The Royals have traded reliever Jason Grimsley to the Orioles for 23-year old pitching prospect Denny Bautista. Grimsley leaves the team as the leader in appearances with 32 in 2004. That’s nothing new for Grimsley, who has appeared in more games than any other American League reliever since 2001. Bautista has a record of 3-5 with Baltimore’s Class AA club this season.
