PARIS (AP) -- The Latest from the French Open (all times local):
American teenager Coco Gauff's French Open debut has ended in the second round after she double-faulted 19 times in a 4-6, 6-2, 7-5 loss to 159th-ranked qualifier Martina Trevisan.
Gauff double-faulted twice in the last game of the 2-hour, 11-minute match.
The 16-year-old Gauff has reached at least the third round at the other three major tournaments.
For Trevisan, a 26-year-old from Italy, this was her first victory in a Grand Slam match played to its conclusion.
She lost in the first round at the Australian Open this year in her first appearance at a major, then advanced Sunday at Roland Garros when her opponent, Camila Giorgio, stopped playing in the second set because of an injury.
Against Gauff, Trevisan kept yelling, ''Yes!'' and ''Let's go!'' in Italian between points, then let out a high-pitched scream when the match ended.
Kei Nishikori's first Grand Slam tournament since having right elbow surgery and contracting the coronavirus is over.
Stefano Travaglia beat the Japanese player 6-4, 2-6, 7-6 (7), 4-6, 6-2 in the second round of the French Open after nearly four hours.
Nishikori, who was once ranked No. 4 but is now down to No. 35, missed the U.S. Open after testing positive for COVID-19.
The 74th-ranked Travaglia is one of an modern-era record of six Italian men who reached the second round at Roland Garros.
Kiki Bertens left the court in a wheelchair following a drama-filled 7-6 (5), 3-6, 9-7 win over 2012 finalist Sara Errani in the second round of the French Open.
Apparently struggling with cramps, the fifth-seeded Bertens was treated by a trainer both during and after the 3 hour, 11 minute match.
Afterward, Errani accused Bertens of faking her pain.
Bertens saved a match point with a forehand cross-court winner when Errani served for the match at 6-5 in the third.
Struggling with her ball toss, Errani often resorted to underhand serves. She had 14 double-faults.
Defending champion Rafael Nadal reached the third round of the French Open by beating American player Mackenzie McDonald 6-1, 6-0, 6-3.
The No. 2-seeded Spaniard is looking to win his record-extending 13th French Open title and equal Roger Federer's men's record of 20 major titles overall.
Nadal improved his record at Roland Garros to 95-2 when he sealed victory on his first match point.
He next faces either Kei Nishikori of Japan or Stefano Travaglia of Italy.
Sebastian Korda has now beaten two tour veterans in his first French Open.
After eliminating Andreas Seppi in his opening main draw match, the 20-year-old American qualifier took out 21st-seeded John Isner in the second round with a 6-4, 6-4, 2-6, 6-4 win.
A former junior world No. 1 and winner of the boys title at the 2018 Australian Open - and the son of 1992 French Open finalist Petr Korda - Korda broke Isner's normally dominant serve five times.
The No. 213-ranked Korda will next face either Mikhail Kukushkin or qualifier Pedro Martinez on Friday.
Also, No. 27-seeded American Taylor Fritz reached the third round by serving 16 aces in a straight-set victory over Radu Albot.
U.S. Open runner-up Victoria Azarenka is out of the French Open in the second round.
The 10th-seeded Azarenka lost to 161st-ranked Anna Karolina Schmiedlova 6-2, 6-2.
Azarenka's exit means all four women who reached the semifinals in New York earlier this month already are gone in Paris. Serena Williams withdrew from the French Open because of an injured Achilles tendon, Jennifer Brady lost in the first round at Roland Garros and U.S. Open champion Naomi Osaka did not make the trip to France.
Schmiedlova had lost 13 consecutive Grand Slam matches in a streak dating to 2015 until beating Venus Williams in the first round this week.
Azarenka is a former No. 1 and a two-time champion at the Australian Open.
Elina Svitolina could not hold back the tears when remembering her favorite mascot.
The third-seeded Ukrainian player was speaking in her post-match news conference after beating Renata Zarazua 6-3, 0-6, 6-2 to reach the third round.
She was asked at the end of the session how important the mascot called Bobik had been in her life, and whether she still had it.
Svitolina soon wiped away her tears.
''Well, it's a really good question. Actually very sad for me because in 2018 I lost him,'' she said. ''It was very sad.''
Svitolina became even more tearful and took a few moments to compose herself.
''Sorry. I lost him. Yeah, it's like this,'' she said. ''It's a toy, but he was my talisman, my lucky charm.''
Dominik Koepfer was about to serve in his match against Stan Wawrinka on Court Suzanne Lenglen when he was startled by a sonic boom.
Koepfer's shoulders dropped into a defensive position and he stopped his service motion.
People all around Paris were were rattled when that loud bang arrived because no one immediately could be sure what caused it.
Police officers outside the tournament grounds were told to cordon off an area nearby.
Police soon wrote on Twitter that it wasn't an explosion. They said it was ''a fighter plane which has broken the sound barrier.''
Serena Williams is out of the French Open.
The American pulled out of the tournament before her second-round match against Tsvetana Pironkova because of an Achilles injury.
Williams hurt her left leg during a semifinal loss at the U.S. Open three weeks ago.
This is her earliest exit at any Grand Slam tournament since a second-round loss at Roland Garros in 2014.
She also withdrew from the French Open two years ago because of an injury before she was supposed to play Maria Sharapova in the fourth round.
