Newly crowned French Open champion Coco Gauff was stunned on her return to action Thursday, losing to Chinese qualifier Wang Xinyu 6-3, 6-3 at the Berlin Open.

The second-ranked Gauff, who won at Roland-Garros less than two weeks ago for her second Grand Slam title, amassed 25 unforced errors and seven double faults in her loss to Wang.

Gauff had a bye to the second round at the grass-court tournament, a warmup for Wimbledon.

Richards tracked the ball as it flew into the box on a curving free kick from Sebastian Berhalter in the 62nd minute to tap the ball with his left foot past Saudi Arabia goalkeeper Nawaf Al Aquidi.

Real Madrid star Mbappe discharged from hospital >> Kylian Mbappe was discharged from the hospital after experiencing an acute case of gastroenteritis, and it was not known when he will be able to play for Real Madrid at the Club World Cup.

Mbappe missed the Spanish giant’s opening game of the tournament — a surprise 1-1 draw against Saudi Arabian team Al Hilal in Miami — because of a fever.

Coach Xabi Alonso said the France international was in “rough shape” and hadn’t been able to train for days. His illness casts doubt over what part he might be able to play in the monthlong tournament in the United States, with Madrid facing Pachuca in Charlotte, North Carolina, on Sunday.

Scheffler shoots 62 to share lead at Travelers >> Scottie Scheffler had one of those rare rounds where he hit a shot so pure it makes his confidence soar. So many other shots were pretty good, too, and they added to an 8-under 62 to share the lead with Austin Eckroat in the Travelers Championship.

The week after a rough-and-tumble U.S. Open was a welcome break for so many at the TPC River Highlands, even with the rough just as long (but not quite as thick) as soaked Oakmont.

Rory McIlroy played bogey-free for a 66 and didn’t look to break too much of a sweat.

Thitikul goes on a birdie streak >> Jenno Thitikul walked off the fifth green after a double bogey in the first round of the KPMG Women’s PGA Championship reminding herself to stay patient and that some missed shots are going to happen.

Thitikul certainly found a way to do that, finishing with a 4-under 68 for a one-stroke lead over Minjee Lee (69). Haeran Ryu, Rio Takeda and Somi Lee all shot 70.

That only hole over par for Thitikul was followed by a par before she made five birdies in a six-hole stretch, with a 60-footer on the par-3 eighth hole in the middle of three in a row.

Thitikul played with top-ranked Nelly Korda (72) and No. 3 Lydia Ko (75).

Gonzalez and Kjeldsen share the lead at Firestone >> Soren Kjeldsen of Denmark and Ricardo Gonzalez of Argentina each shot 3-under 67 on Firestone South to share the lead after the opening round of the Kaulig Companies Championship, the third major of the year on the PGA Tour Champions.

Stewart Cink, who lost in a four-hole playoff to Tiger Woods at Firestone in 2006 at a World Golf Championship, was poised to take the lead until two bogeys on his final three holes.

Nola had been out since early May with the ankle injury.

Nola was 1-7 with a 6.16 ERA in nine starts this year before injuring his ankle on May 8 during pregame agility drills.
