Sunday at Shinnecock lacked much of the hysteria of the day before, but it still featured its share of fireworks: a closing 63, a run by the reigning Masters champion, and two close friends battling in the day’s penultimate group.

Ultimately it was Brooks Koepka who prevailed over a cast of challengers that included Englishman Tommy Fleetwood, pal Dustin Johnson, and recent green jacket winner Patrick Reed to claim his second major championship and become the first back-to-back winner of the U.S. Open since Curtis Strange in 1988-89.

Below, some of our favourite images from the final day at the Open.
