Callaway Golf Company signed Maverick McNealy, who turns professional this week after playing on the victorious U.S. Walker Cup team. The 21-year-old Stanford alum rose to No. 1 in the world amateur rankings in 2015, a position he also held during the 2016 and 2017 seasons.

McNealy won 11 times during his dominant amateur career, including the 2015 Pac-12 Championship, 2015 U.S. Collegiate Championship, and the 2016 Western Intercollegiate. While at Stanford, he won the 2017 Ben Hogan award, given annually to the nation’s top college golfer, as well as the Byron Nelson Award, and the Mark McCormack Medal.

He represented the U.S. at the 2015 and 2017 Arnold Palmer Cup, and the 2016 Eisenhower Trophy. McNealy also played on his second U.S. Walker Cup team last month, posting a perfect 4-0 record.

“I have played Callaway equipment at the biggest amateur events this year, and I am extremely confident with how these clubs perform,” said McNealy, who will make his first professional start this week at the Safeway Open. “I’ve been particularly impressed with my driver and golf ball, and I know this is the best equipment choice for me as I start my professional career.”

As a full Callaway Staffer, McNealy will use Callaway clubs, balls, bag, gloves and an Odyssey putter. He is currently playing a GBB Epic driver and a Chrome Soft X ball, both of which were in the bag at the Walker Cup.

McNealy will add to Callaway’s tremendous group of talented young players, a list that currently includes Patrick Reed, Daniel Berger, Adam Hadwin, Wesley Bryan, Ollie Schniederjans, Aaron Wise, Branden Grace, Thomas Pieters, Michelle Wie, Grayson Murray, Patrick Rodgers and Emiliano Grillo.

McNealy has also been recognized for having diverse interests outside of golf, including hockey and business. His father, Scott McNealy, co-founded Sun Microsystems.
