JEJU ISLAND, South Korea (AP) Brooks Koepka has improved his chances of taking over as No. 1 golfer in the world, shooting a bogey-free 5-under 67 Saturday for a four-stroke lead after three rounds of the CJ Cup at Nine Bridges.
Koepka had a three-round total of 13-under 203. Ian Poulter, who shot 68 Saturday, was tied for second place with second-round leader Scott Piercy, who had a 72.
The 28-year-old Koepka, who trailed by one stroke after two rounds, will move to the top of the world rankings if he wins the tournament and former No. 1 Justin Thomas, the defending champion here, does not finish any better than second.
