Koepka tops CJ Cup, moves to world No. 1

JEJU ISLAND, South Korea – Brooks Koepka is golf’s new No. 1 after winning the CJ Cup at Nine Bridges on Sunday by four strokes.

Koepka, who displaced Dustin Johnson for the world’s top ranking, shot a final-round 8-under 64 for a 21-under total of 267. Koepka, who had never held the top ranking, led by four strokes after three rounds.

Koepka is the third player this year to reach No. 1 for the first time, joining Justin Rose and Thomas. The last time that happened was in 1997, when Ernie Els, Tom Lehman and Tiger Woods each rose to No. 1.
