Callaway Golf Co. has signed a promising young golfer, Maverick McNealy, to its staff.

McNealy is the former No. 1 world amateur and a Stanford alumnus. He is making his professional debut during the Safeway Open Oct. 2-8 in Napa.

Callaway (NYSE: ELY) announced its new relationship with McNealy on Oct. 3. Financial terms of the deal were not disclosed. As a Callaway staffer, McNealy will use the Carlsbad business’ clubs, balls, bag, gloves and an Odyssey putter.

The news came one week after Callaway announced it struck a new, lifelong deal with pro golfer Phil Mickelson.

McNealy announced on his Twitter feed Oct. 3 that he was also partnering with KPMG and UnderArmour.

The 21-year-old won the Ben Hogan Award, an honor given to the nation’s top college golfer, in 2017. In September he was part of the winning U.S. team in the Walker Cup, which pits the United States against Great Britain and Ireland.

McNealy also has interests in hockey and business. And he has a front-row seat to the business world since he is the son of Scott McNealy, co-founder of Sun Microsystems.
