FARMINGDALE, N.Y.: A coronation almost turned into a calamity but Brooks Koepka survived to win the PGA Championship for a second consecutive year on Sunday and establish himself as golf’s new top dog. Koepka shot a four-over-par 74 to finish at eight-under 272 and captured his fourth major title in his last eight starts in grand slam events. In becoming the first champion to lead wire-to-wire since Hal Sutton in 1983, Koepka successfully defended his title and also displaced Johnson as world number one. Koepka, who also won back-to-back U.S. Open titles in 2017-18, admitted his run of bogeys had put him under pressure. “Tell you what, the hour spent from number 11 to 14 was interesting,” Koepka said.
