TORONTO (AP) -- Duane Ward, a two-time World Series champion and one of the most accomplished relievers in Toronto Blue Jays history, has died of natural causes, the team announced Sunday. "Duane will always be a cherished part of the Blue Jays family, and we will be forever grateful for his contributions to our organization and to baseball in Canada," the team said in a statement. Before their game Sunday against the Chicago White Sox, the Blue Jays paid tribute to Ward with a scoreboard montage and a brief moment of silence. That total remains the Blue Jays' single-season record. Ward was the winning pitcher in the Game 6 of the 1993 World Series against Philadelphia, which was decided by Joe Carter's series-winning home run.
