Add the French Open to Coco Gauff's list of Grand Slam tournaments where she has beaten seeded opponents.
The 16-year-old American made her main-draw debut at Roland Garros a successful one by eliminating No. 9 seed Johanna Konta 6-3, 6-3 at Court Suzanne Lenglen on Sunday.
Konta was a semifinalist a year ago in Paris, while Gauff lost in qualifying rounds.
It was at the next major tournament, Wimbledon, where Gauff made her breakthrough, becoming at 15 the youngest player ever to qualify at the All England Club -- and then beating Venus Williams en route to the fourth round.
Gauff then reached the third round at the US Open last year, and the fourth round at the Australian Open this year, beating 2019 champion Naomi Osaka along the way.
Things had been a bit tougher for Gauff lately: She entered the French Open having lost four of her past five matches. But she handled the cold weather and heavy conditions better than Konta, a three-time Grand Slam semifinalist.
"When I'm on the court, I can act like I'm used to it," Gauff said. "When I'm off the court, I'm just happy to be here.''
Top-seeded Simona Halep won 10 straight games in beating Sara Sorribes Tormo 6-4, 6-0 to reach the second round of the French Open on Sunday and extend her winning streak to 15 matches.
Halep won on her 29th birthday, but with minimal celebrations planned for the evening since the coronavirus pandemic means players stay locked inside the security bubble of their hotels.
"It was really special day playing on Roland Garros on my birthday," she said. "I cannot celebrate much because I have to stay in the room, so I will have a bottle of water."
Wearing thick black leggings and a long-sleeved pink jersey to combat the chilly conditions on Court Philippe Chatrier, the 2018 champion made a series of unforced errors and trailed 4-2.
"I felt the cold. I'm not very happy with the cold in general," Halep said. "So it was a little bit tough; I struggled."
But then she found her range, clinching the first set with a hold to love and sealing victory on her first match point when her Spanish opponent clipped a forehand wide.
Halep is ranked second but seeded first at Roland Garros because defending champion Ash Barty skipped coming to Paris because of coronavirus concerns. Halep won titles on clay in Prague and Rome, and her winning run -- interrupted by the pandemic -- dates to February.
She next faces either countrywoman Irina-Camelia Begu or Jil Teichmann of Switzerland.
Halep was not alone in wrapping up warm.
Over on Court Suzanne Lenglen, US Open runner-up Victoria Azarenka experienced a vastly different temperature to Flushing Meadows only two weeks ago.
The 10th-seeded Azarenka, who beat Danka Kovinic 6-1, 6-2, fumed when match officials didn't immediately send them back to the locker room during a rain interruption.
"I am going to get frozen," she complained. "No. I'm not waiting here a couple of minutes because I'm cold. It's 8 degrees [Celsius], 8 degrees, I live in Florida, I am used to hot weather."
Before walking off court, Azarenka grumbled "it's ridiculous. It's too cold ... What's the point? Sitting here like ducks."
After the match, she said the conditions were risky.
"I think my opponent slipped in the third game, so I think she was also feeling a little bit uncomfortable," Azarenka said. "Does it increase the risk of players getting injured? Absolutely, I think that it does."
She next faces Anna Karolina Schmiedlova, who won 6-4, 6-4 against American veteran Venus Williams.
"Even on my really good shots, she had a lot of amazing replies that just kind of came out of nowhere," Williams said. "Give her credit to playing an amazing match."
The 40-year-old Williams exited in the first round at Roland Garros for the third straight year and is 0-3 in Grand Slam tournaments this year following the Australian Open and the US Open. Since the start of 2018, the seven-time Grand Slam champion has lost in the first round in seven of the past 11 major tournaments.
Belgium's Elise Mertens -- seeded 16th -- rolled to a 6-2, 6-3 win over Margarita Gasparyan.
No. 17 Anett Kontaveit lost 6-4, 3-6, 6-4 to Frenchwoman Caroline Garcia, but No. 20 Maria Sakkari and No. 27 Ekaterina Alexandrova both advanced.
