NEW YORK — Kevin McGuiness has resigned after five years as chief operations officer of the Major League Baseball Players Association and been replaced by Xavier D. James, who had been his deputy.
James, 51, was hired by the union last year after working as lawyer for gospel singer DeLeon Richards Sheffield, the wife of former All-Star outfielder Gary Sheffield. James will oversee organizational infrastructure, human resources, staffing and budgeting.
A graduate of the University of California at Irvine and George Washington Law School, McGuiness taught Renaissance history and English literature in Florence, Italy. He had been president of the McGuiness Group, a lobbying firm that represented the MLBPA, before joining the union at the start of 2014. The players’ union said Monday that he will return to private practice, and will represent the union in that role.
Leonor Colon was promoted to senior director of international and domestic player operations from director of player operations. She worked for the commissioner’s office from 2000 to 2004 and the New York Mets from 2008 to 2010 before joining the union. She is married to Tim Slavin, the union’s chief of business affairs.
