Pirates DFA Vance Worley to make room for Joe Blanton

PITTSBURGH -- The Pirates designated pitcher Vance Worley for assignment on Thursday to make room on the roster for newly acquired reliever Joe Blanton.

Pittsburgh acquired Blanton from Kansas City early Thursday for cash considerations. Blanton went 2-2 with a 3.94 ERA and two saves in 15 appearances for the Royals this season, including four starts.

Worley bounced between the rotation and the bullpen for Pittsburgh, going 4-5 with a 3.78 ERA in 20 appearances. He has struggled recently, giving up at least one run in five of his last six appearances since June 28.
