The Orioles traded right-handed pitcher Mickey Weston to the Toronto Blue Jays in exchange for left-hander Paul Kilgus, the Orioles announced Friday.

In addition, the Orioles will not exercise the $575,000 option to sign on Ron Kittle's contract, General Manager Roland Hemond said. Kittle, therefore, becomes a free agent and receives $100,000 buyout. The Orioles traded outfielder Phil Bradley for Kittle in a deal with the Chicago White Sox last season.
