WIMBLEDON, England — As the top seed at Wimbledon and reigning French Open champion, Simona Halep was always going to be a focus of attention.

By the time she played her third-round match at the All England Club, she was being watched with the type of concern normally reserved for endangered species.

Entering Saturday, eight of the top 10 seeds in women’s singles had been eliminated. Then Halep joined them, falling in the third round, 3-6, 6-4, 7-5, to 48th-ranked Hsieh Su-wei.

Of the top 10 women, only No. 7 Karolina Pliskova reached the fourth round.

Halep, who did not play any warmup events on grass before Wimbledon, attributed her loss to fatigue from the first six months of the season, which included reaching the Australian Open final, wresting back the No. 1 ranking, reaching a final in Rome and winning the French Open. Halep said she hit a wall, mentally, and was unable to rouse herself.

“I just believe that I was not very positive on court,” she said. “The match was very unprofessional for me. But I am too tired. I was too tired. I have pain everywhere. I will not find the excuses about this match — she deserved to win — but still I’m sad about myself today.”

Halep had a match point with Hsieh serving at 4-5 in the third set, but Hsieh fended it off by leaning into a darting backhand down the line.

That injection of power was rare from Hsieh, who plays an almost avant-garde version of tennis. She opts for twists and dinks and chips when most would opt for thumps and slaps. She enjoys prolonging rallies and getting to run around the court.

The formula has worked. Hsieh has pulled off three recent upsets of top 10 players at Grand Slam tournaments, including a victory against Garbiñe Muguruza in the second round of this year’s Australian Open.

Djokovic slams Wimbledon crowd

Novak Djokovic shrugged off a bad call by the chair umpire that cost him a break in his Wimbledon win over home favorite Kyle Edmund on Saturday.

He was less forgiving when it came to the way he was treated by the crowd at the All England Club.

“There is a certain unwritten borderline where you feel that it’s a bit too much,” Djokovic said about being booed at times by the partisan crowd on Centre Court. “I didn’t deserve to be treated the way I was treated by certain individuals.”

Neither the crowd nor a big mistake by the umpire could unglue Djokovic, though, as the three-time champion won 4-6, 6-3, 6-2, 6-4 to reach the round of 16 for the 11th time at the All England Club.

He was robbed of a break at 3-3, 15-40 in the fourth set when the ball bounced twice before Edmund managed to return it over the net. Djokovic complained to the chair umpire but the call stood — even though TV replays also showed Edmund’s shot had actually landed wide.
