Jamie Lovemark, United States
2007 – World number one for eight weeks
Lovemark holds the distinction of being the first American to hold the number one position on the World Amateur Golf Ranking®. The Rancho Santa Fe, California native took over the number one spot after helping the United States win the 2007 Walker Cup at Royal County Down.
Lovemark, who won all three matches he played, was always a shoe-in for the U.S team after winning the 2007 NCAA Championship, college golf’s most prestigious prize. The University of Southern California student also appeared on the U.S. Palmer Cup team that year, winning both his singles matches to help his country win 18-6.
In 2005, he won the Western Amateur Championship.
Unsurprisingly, Lovemark turned professional in 2009 with huge expectations on the shoulders of his six-foot, four-inch frame. He impressed early on the PGA Tour, finishing runner-up in the 2009 Frys.Com Open after a playoff with Walker Cup teammate Rickie Fowler and Troy Matteson, which Matteson won. The 2010 season saw Lovemark become the youngest player at 22 to win the Nationwide Tour (now the Korn Ferry Tour) money list thanks to a win and three runner-up finishes.
Unfortunately, a back injury in 2011 which required surgery curtailed his rookie PGA Tour season and his 2012 campaign. Lovemark won his second professional title in 2013, the Midwest Classic on the Web.com Tour (now the Korn Ferry Tour).
Lovemark has struggled with various injuries for much of his professional life. He has yet to win on the PGA Tour, with his best season a 49th place finish on the 2016 FedEx Cup standings thanks to runner up in the Zurich Classic of New Orleans.
Su-Hyun Oh, Australia
2013 – World number one for two weeks
Oh took over the number one spot on the WAGR® table in October 2013 thanks to a string of good performances. She teed off the season with a 13-shot victory in the prestigious Lake Macquarie Amateur Championship, and had second place finishes in the Riversdale Cup and Volvik RACV Masters, the latter a professional tournament. She ended 2012 by winning the Port Phillip Open Amateur & Victoria Amateur Championship by nine shots. She also won the Dunes Medal, the Srixon International Junior Girls’ Classic and the Australian Girls’ Amateur Championship.
The member of Melbourne’s Kingswood Golf Club turned professional in 2014 after helping Australia win the Espirito Santo Trophy at the World Amateur Team Championship in Japan. She earned her first professional win in 2015 by taking the RACV Australian Ladies Masters title on the Ladies European Tour.
Oh, who was born in South Korea but moved to Australia when she was eight, represented Australia in the 2016 Olympic Games in Rio, placing 13th. She joined the LPGA Tour in 2016 after finishing 32nd at the LPGA Qualifying School.
In just over of four seasons on the LPGA Tour, Oh has won just under $2 million. Her best season to date came last year when she finished 33rd on the LPGA money list thanks to two second place finishes – the Meijer LPGA Classic for Simply Give and the ISPS Handa Vic Open.
Oh is currently ranked 59th on the Rolex Rankings. She reached a career high of 40th in 2016 after an eighth-place tie in the KPMG Women’s LPGA Championship.
