Question: Who won the us open golf in 2017?

Disambiguated questions and answers:
context: Brooks Koepka tied the U.S. Open scoring record and won his first career major championship by four strokes over Brian Harman and Hideki Matsuyama. Beginning the round a shot out of the lead, Koepka quickly erased the deficit with birdies on his first two holes. After saving par with an eight-foot putt on the 13th, he then recorded three straight birdies on his way to a round of 67 (−5). His total of 16-under par tied the tournament scoring record set by Rory McIlroy in 2011. Harman entered the round with the lead but fell into a tie for second with three bogeys on the back-nine. Matsuyama shot the low round of the day with 66 (−6) and jumped into a tie with Harman. After establishing a new tournament scoring record in the third round, Justin Thomas bogeyed three of his first five holes and finished three-over on the round to drop to a tie for ninth. Tommy Fleetwood also began the round a shot behind but three bogeys on the front-nine dropped him from contention. The low amateur was Scottie Scheffler, who finished at –1, beating Cameron Champ by just one stroke. In all, thirty-one players finished the tournament under par, breaking the U.S. Open record set in 1990.

context: Since 1911, the title has been won mostly by players from the United States. Since 1950, players from only six countries other than the United States have won the championship, most notably South Africa, which has won five times since 1965. A streak of four consecutive non-American winners occurred from 2004 to 2007 for the first time since 1910. These four players, South African Retief Goosen (2004), New Zealander Michael Campbell (2005), Australian Geoff Ogilvy (2006) and Argentine Ángel Cabrera (2007), are all from countries in the Southern Hemisphere. Northern Ireland's Graeme McDowell (2010) became the first European player to win the event since Tony Jacklin of England in 1970; three more Europeans won in the next four editions, making it only three American wins in the 11 tournaments from 2004-2014.
