Kerwin Danley became the first African American umpire crew chief in Major League Baseball when a series of promotions, additions and retirements were announced Thursday.
The moves included Alfonso Marquez being elevated to the second Hispanic crew chief in MLB history.
Crew chiefs Jeff Kellogg, Dana DeMuth, Gary Cederstrom and Mike Everitt have retired. Kellogg and Everitt will move into jobs as MLB umpire supervisors.
