SAN MARTIN, Calif. — Eleven years after finishing as runner-up as an amateur in her first U.S. Women’s Open, Brittany Lang won her first major title – with help from a playoff penalty on Anna Nordqvist.

Lang made par on all three holes of the aggregate playoff and Nordqvist was given a two-stroke penalty for touching the sand with her club in a fairway bunker on the second playoff hole Sunday, helping deliver Lang the title.

The players were not told of the penalty until they were in the middle of playing the final hole after officials reviewed replays in the latest controversy at a USGA event.

Lang then sealed the win with a short par putt on the final playoff hole, while Nordqvist made bogey to lose by three shots.

At last month’s men’s U.S. Open, eventual winner Dustin Johnson played much of the final round not knowing if he would be penalized one stroke because his ball moved as he addressed it on the fifth green. The penalty ended up proving moot as Johnson won by three shots.

Lang shot a 1-under 71 to finish with a 6-under 282 for the tournament at CordeValle for her second win in 287 tournaments on the LPGA Tour. She survived a bogey on the 17th hole that led to the playoff before recovering in the playoff for a breakthrough win at age 30.

Both players made pars on the first hole of the playoff, which was played on the final three holes of the course. Things got interesting on the next hole after Nordqvist hit her tee shot into a fairway bunker.

While preparing to hit the shot, Nordqvist’s club barely touched the sand. She did not realize it and both players made par on the hole, heading to the final playoff hole seemingly tied.

But television replays showed the infraction and USGA officials studied the video before determining if the two-stroke penalty was necessary. An official told Nordqvist about the penalty after she hit her third shot on the 18th hole but before Lang did, giving her a possible advantage.

Lang hit her shot onto the green and then two-putted for the win, getting hearty congratulations from many of her fellow Americans on tour after she joined Michelle Wie (2014) as the only U.S. golfers to win the Open in the past six years.

Lang capitalized on a surprising final-round collapse by world No. 1 and 54-hole leader Lydia Ko, who made a double-bogey 7 on the ninth hole and shot 3-over 75 on the day, finishing two shots off the lead in a four-way tie for third with Amy Yang, Sung Hyun Park and 2009 winner Eun Hee Ji.

EUROPEAN TOUR: Alex Noren held off his pursuers to win the Scottish Open at Inverness by one shot for his fifth victory on the tour.

The Swede shot 2-under 70 to finish on 14-under 274, with playing partner Tyrrell Hatton (69) the runner-up at Castle Stuart. Nicolas Colsaerts (66), Danny Lee (69) and Matteo Manassero (70) were two shots back.

Hatton, Colsaerts, Manassero and Richie Ramsay took the final four qualification places for next week’s British Open.

CHAMPIONS TOUR: Paul Goydos shot a bogey-free 69 to win the Dick’s Sporting Goods Open at Endicott, N.Y.

A birdie at the 17th hole gave Goydos a two-shot victory over Wes Short Jr. (69) as he finished at 14-under-par 202 for his third victory on the tour.

Qualifier Neal Lancaster (70) was third at 11 under.
