Two weeks away from her 20th birthday, Inbee Park became the youngest winner of the U.S. Women’s Open on Sunday by closing with a 2-under 71 as everyone else around her faded away at Interlachen.

Park didn’t make a bogey over the final 10 holes, pulling away with three clutch putts early on the back nine and building a four-shot lead going to the final hole. She finished with a tap-in birdie, and a few of her fellow South Koreans doused her with beer.
