Koepka and Rory McIlroy share the record for the lowest score ever to win a US Open, with minus-16 in 2017 and minus-16 in 2011. Walter Hagen's plus-17 winning score in 1919 is the best of all time. In 2006 and 2007, Geoff Ogilvy and Angel Cabrera each shot plus-5 for the greatest winning scores since 1975.
