Answer: Bob Wickman
Bob Wickman began his MLB career with the New York Yankees back in 1992. The Yankees let him try his hand at being a starting pitcher in 1993 and he had some success with a 14-4 record but his ERA was well over 4.00.
Wickman found his way back into the bullpen and turned out to be a reliable arm for high stress situations for a long time.
He found his way to the Atlanta Braves organization at the tail end of his career. After going 3-5 with 38 saves and a 2.84 ERA in almost 70 innings of work, Wickman went to the Diamondbacks where his career would come to a close following the 2007 season.
