German women's tennis player Tatjana Maria lost 6-4, 6-0 to Coco Gauff in the second round of the women's singles tournament at the U.S. Open on Wednesday.

On Friday, Maria admitted she napped during the U.S. Open in between matches, since her match against Gauff was at 7 p.m. Maria is a 37-year-old mother of two from Germany. 

"In the evening, I get tired, like everybody else, so that’s why I have to take a nap," she said. "I have to rest pretty much the whole afternoon to be ready for the evening."

Maria is not even the only player who has napped in between matches in Flushing, Queens this week. Zhang Zhizhen, 27, who won a silver medal for China in mixed doubles at the Paris Olympics, admitted to it as well. Zhizhen lost in the first round to England's Jack Draper on Tuesday. 

"If I feel tired, I want to sleep, so I go to sleep. Maybe if I have the first match at 11 a.m., I don’t have enough time. But any other match, I probably will take a nap for 10 or 15 minutes," he said. "Sometimes in the afternoon, I will sleep for one or two hours."

Meanwhile, Gauff is moving on to third round against Ukraine's Elina Svitolina on Friday. She will look to defend her U.S. Open singles title after taking the event by storm last year at just 19 years old.

At Wimbledon in early July, Gauff lost in the women's singles round of 16 to Emma Navarro and then in the doubles quarterfinal. She then lost at the Paris Olympics in the third round of women's singles, the second round of women's doubles and the quarterfinals of mixed doubles. 

At the Canadian Open on Aug. 9, as the top seed, she lost in the round of 16 to lesser-known opponent and 14th-seeded Diana Shnaider. Gauff's recent appearance at the Cincinnati Masters may have been her worst one yet, when she lost her very first match in the round of 32 to Yulia Antonovna Putintseva of Kazakhstan.
