Gore turned professional in 1997. In 2005, he played on the
PGA Tour after moving from the
Nationwide Tour mid-season, after receiving a battlefield promotion, which is given when a player wins three Nationwide Tour events in one season. Gore has one PGA Tour win, the
84 Lumber Classic in 2005, and is the all-time leader in career wins on what is now the Korn Ferry Tour, with seven. He is the first golfer to earn a three-win promotion and a PGA Tour win in the same season. Gore belongs to a small group of players who have shot 59 in their careers. His historic round of 59 happened on Friday of the 2005
Cox Classic at Champions Run in Omaha, Nebraska. Gore played in the final group of the
2005 U.S. Open with
Retief Goosen. He shot a 14-over-par 84 to drop all the way to a tie for 49th;
Michael Campbell won the event. Gore was not fully exempt on the PGA Tour from 2009 to 2014. Gore had a strong 2015, but a poor 2016 saw him finish outside 150th, limiting him to past champion status for 2017. During the third round of the 2016
Farmers Insurance Open at
Torrey Pines, Gore made a
double eagle on the par-5 18th hole. After injuries and poor play, Gore went into the insurance business. In 2018, he received his license and is one of the co-founders of Kirkman Gore Insurance Services. As a comeback from his retirement, Gore earned a sponsor exemption for the 2018
RSM Classic on the
PGA Tour. After three rounds, he was in second place, a stroke behind leader
Charles Howell III after posting scores of 68, 63 and 67. In the final round, Gore shot +2 and finished T15 for the tournament. In March 2019, Gore was named the first player relations director for the USGA. In June 2024, he made his debut on the
PGA Tour Champions. ==Personal life==
