On Sunday, Jon Rahm won the 121st US Open and his first major victory with two long birdie putts on the final two holes, beating South African Louis Oosthuizen with one shot.

At the par-4 17th hole, the 26-year-old Spaniard curled in a stunning birdie putt from just within 25 feet, then scored his fourth birdie of the week at the par-5 18th, blasting out of a bunker and rolling in an 18-footer to take the lead.

Rahm only could watch 2010 British Open winner Oosthuizen play the final four holes after astonishing, fist-pumping putts to get to the clubhouse.

At the age of 17, Oosthuizen blasted his tee shot left into the bushes and made par to fall two back, and a closing birdie still earned him a major runner-up for the sixth time in his career.

Rahm finished 72 holes on six-under 278, its only leader to play bogey-free here on back nine, with Oosthuizen on 279 and American Harris English third on 281.

Rahm became only the fourth US Open winner to finish with back-to-back birdies, joining Jack Nicklaus, Tom Watson, and Ben Hogan, on the same track wherein he won his maiden US PGA title in 2017.

After Sergio Garcia, Jose Maria Olazabal, and the late Seve Ballesteros, he has become the first Spaniard to win the US Open and the fourth Spaniard to win a major title.

Third-ranked Rahm also won over as world number one when top-ranked Dustin Johnson tied for 19th on 286. Rahm momentarily atop the rankings after winning the Memorial last year, however, he tested positive for Covid-19 at the tournament two weeks ago and remained last week in quarantine. At 17, Rahm curved the six-foot-break putt from left to right, saw the ball go into the cup, and pumped the air.

Rahm proceeded to the 18th hole, the easiest ending hole in US Open history, and produced an incredible putt and also a right-hand uppercut. Rahm has seven previous top-10 major finishes without a win, including a tie for third at the US Open in 2019.

As the anticipation mounted, the world's top five players, including four-time major champion Rory McIlroy, have been within three strokes of the lead. The opponents faded one by one, left behind Rahm and Oosthuizen to slog out pars in the last holes.

Bryson DeChambeau, the defending winner, took two bogeys and two double bogeys on the back nine on his route to a 77 and a share of 26th on 287.

McIlroy, a four-time major champion, made bogey at 11 and a double-bogey at 12 on his route to a 73 and a share of seventh place on 283.

Nelly Korda won the Meijer Classic on Sunday with a five-under-par 67, becoming the LPGA Tour's first two-time champion this season.

Korda, 22, of the United States, finished at 25-under 263 to defeat Ireland's Leona Maguire with two strokes and establish the tournament record at the Blythefield Country Club course in the US state of Michigan.

Maguire took solo second place with a 66. World No. 4 Korda and some others utilized this week's event as a warm-up for the Women's PGA Championship, which is set to take place next week in Atlanta, Georgia.

Korda entered her final round with a three-shot lead after shooting a career-best 62 in the third round. She entered a select group of golfers who have drained 11 birdies in a round, second only to Annika Sorenstam's 2001 LPGA Tour record of 13 birdies. Korda rebounded this week after missing the cut at the US Women's Open two weeks earlier. This is her sixth career championship.
