Born Aug. 7, 1978, in Durban, the third largest city in South Africa, Mulroy was introduced to golf as a child, caddying for his father. He learned to play early and experienced many of the premier courses scattered throughout South Africa. He also got help from his grandfather, who was a frequent playing partner of PGA Hall of Famer Bobby Locke.
After playing rugby on South Africa's State U21 team, Mulroy moved to the United States for college. He settled in North Carolina, which he still called home in 2009, and attended North Carolina State University, where he soon became a NCAA Division I All-American. He turned professional in 2003.
Mulroy played on the Asian Tour at the beginning of his pro career. His first win came at the 2006 Big Stakes Match Play Championship, where he was partnered with David Ping. Many of Mulroy's most memorable victories came on the Sunshine Tour. In 2008, he won the Vodacom Origins of Golf Western Cape Tournament and the Coca-Cola Charity Championship.
Mulroy ended the 2008 season as the second ranked player on the Sunshine Tour. Afterward, he finished 64th at the PGA Tour Qualifying School, missing the cut for the big league, but earning himself a card for the Nationwide Tour. He has played on the Nationwide for two years, and won the South Georgia Classic in April 2009.
Outside of the tours, Mulroy also won the Big Stakes Matchplay event in the United States in 2005--an accomplishment he calls his greatest thrill in golf--and the Gary Player Invitational with Bobby Lincoln in 2008.
Mulroy is sponsored by Bridgestone and his home is course is the Umkomaas Golf Club in South Africa.
