”Mackie’s presence at the Major League Umpire Retreat in Chandler, Arizona was hugely successful. He made a considerable impact on the entire umpire staff through his presentations and availability throughout the retreat. We are very proud to have him as a resource and asset to our Major League Umpires.”
Richard L. Alderson,
President, San Diego Padres
