The New York Yankees announced Thursday that first-base coach and outfield instructor Reggie Willits will leave at the end of the year to become a volunteer assistant for Oklahoma's college baseball program.

Willits played for Oklahoma in 2002-03 and coached Binger-Oney High School to Oklahoma state championships in 2013-14.

Willits had been with the Yankees for seven years, the first three as minor league outfield and baserunning coordinator and the last four as first-base coach and outfield instructor.
