BEDMINSTER, N.J. — Sung Hyun Park won the U.S. Women’s Open on Sunday for her first LPGA Tour victory.

The 23-year-old from South Korea shot her second straight 5-under 67 and won a day-long battle with front-running Shanshan Feng and teenage amateur Hye-Jin Choi at Trump National Golf Club.

Park, who birdied the 15th to move into a tie for the lead and the 17th to open a two-shot edge after Choi made a double bogey on the previous hole, finished at 11-under 277 for a two-stroke win over Choi.

President Trump attended the biggest event in women’s golf for the third straight day. There was a peaceful protest after he arrived at his box near the 15th green shortly after 3 p.m.

Park needed a fine chip from over the green on the par-5 18th hole to save par, and she got a thumbs-up from Trump as she walked to sign her scorecard.

Choi finished with a 71.

Top-ranked So Yeon Ryu (70) and fellow South Korean Mi Jung Hur (68) tied for third at 7 under. Feng, from China, had a 75 to drop into a tie for fifth at 6 under with Spain’s Carlota Ciganda (70) and South Korea’s Jeongeun Lee (71).

PGA: Bryson DeChambeau overcame a four-stroke deficit to win the John Deere Classic in Silvis, Illinois, for his first PGA Tour title and a spot next week in the British Open.

DeChambeau, 23, birdied four of the final six holes for a 6-under 65 and an 18-under 266 total.

Third-round leader Patrick Rodgers shot a 70 to finish one shot back.

DeChambeau made a 14-foot birdie putt on No. 18 to pull even with Rodgers. Rodgers then bogeyed No. 17.

Wesley Bryan (64) and Rick Lamb (66) tied for third at 16 under.

CHAMPIONS TOUR: Scott McCarron shot a bogey-free 6-under 66 and took advantage of an uncharacteristic crash by three-time defending champion Bernhard Langer to win the Constellation Senior Players Championship in Owings Mills, Maryland.

McCarron finished 18 under to beat Langer and Brandt Jobe by one shot. McCarron made up a six-shot deficit in the final round to capture his first major on the over-50 tour.

The story of the day, however, was the stunning collapse by Langer. Seeking his third major win of the year, the 59-year German had a one-shot lead before dropping his tee shot in the water on No. 17. After taking the one-shot penalty, he missed a 4-footer for bogey.

On 18, Langer lipped out a 6-foot birdie putt that would have forced a playoff. He finished with a 73.

EUROPEAN TOUR: Rafa Cabrera Bello birdied the first hole of a playoff with Callum Shinkwin to win the Scottish Open, securing his first title in 51/2 years.

The 405th-ranked Shinkwin was short on a 4-foot par putt for victory on his 72nd hole, settling for a 4-under 68 that put him into a playoff with Cabrera Bello, who shot a course-record 8-under 64. Both were 13 under overall.
