The St. Louis Cardinals took the risk on lefty Zach Duke and put him toward the back of their bullpen. This move came in the middle of the 2016 season and saw the Cardinals sending prospect Charlie Tilson to the White Sox for Duke.
Duke, in his career, had appeared as a starter and was- in fact- a nemesis of the St. Louis Cardinals during his starting days in Pittsburgh. Never a show-stopping ERA, Duke hovered between 4.00 and 5.00 for the majority of his starting career.
Duke saw his starting career come to an end in 2011 after he had left the Pirates and found himself as a member of the Arizona Diamondbacks.
