Golf - Koepka first repeat U.S. Open champion since 1989

SOUTHAMPTON, N.Y. (Reuters) - American Brooks Koepka became the first U.S. Open champion in 29 years to successfully defend his title when he clinched a one-stroke victory on Sunday.

Koepka staved off a brilliant charge by Englishman Fleetwood, who matched the lowest score in tournament history, a seven-under-par 63 at Shinnecock Hills.

Koepka shot a closing 68 to finish at one-over 281 and become the first to win back-to-back since Curtis Strange in 1988 and 1989.
