Mike Harkey pitched in the Major Leagues from 1988 until 1997 with the Cubs, Rockies, Athletics, Angels, and Dodgers. He was the New York Yankees pitching coach from 2008-2013 before leaving to become the pitching coach of the Arizona Diamondbacks. Harkey is also the only African-American in uniform for the Diamondbacks as t hey have none on their current 25 man roster and he is the only one on the coaching staff. I spoke with him for a few minutes before Arizona took on the Mets at Citi Field.
