LONDON — World number one Jannik Sinner stayed ice cool to move serenely into the Wimbledon second round but it was a second successive day of upsets at a sizzling All England Club as a succession of seeded players crashed and burned on Tuesday.

American second seed Coco Gauff, chasing a French Open-Wimbledon double after her Paris triumph, was the day’s most surprising casualty, losing 7-6(3), 6-1 to Ukraine’s Dayana Yastremska as the sun set on a sultry day.

Gauff’s compatriot Taylor Fritz, the world number five, survived a five-set firefight by the skin of his teeth against big-serving Frenchman Giovanni Mpetshi Perricard.

But the same could not be said of 13 of the men’s seeds who fell at the first hurdle — a Wimbledon record since 32 seeds were introduced in 2001.

Nine seeds also perished in the women’s first round while the eight top-10 seeds to go out across both singles draws amounted to the highest at a Grand Slam in the professional era.

Germany’s Alexander Zverev was the most notable men’s casualty, the third seed losing 7-6(3), 6-7(8), 6-3, 6-7(5), 6-4 to France’s Arthur Rinderknech in a marathon duel that began on Monday and was locked at one set apiece overnight.

“I’m not sure he’s ever played a match like that in his life,” said Zverev, who is still chasing a first Grand Slam title after 38 attempts.

Italian Lorenzo Musetti, seeded seventh, was bundled out on Court Two by Nikoloz Basilashvili — the same court where earlier American women’s third seed Jessica Pegula was sent packing 6-2, 6-3 by Italian Elisabetta Cocciaretto.

A red-hot Sinner never looked like joining the exodus as he beat fellow Italian and close friend Luca Nardi 6-4, 6-3, 6-0 in a victorious return to the Grand Slam stage after his epic French Open final defeat by Carlos Alcaraz last month.

“I tried to put the friendship away for a couple of hours,” Sinner, who conceded only four points when he landed his first serve, told reporters.

Novak Djokovic closed out the day’s action on the main showcourt by getting past Frenchman Alexandre Muller 6-1, 6-7(7), 6-2, 6-2 despite being hampered by a stomach bug midway through his match. He will face Briton Dan Evans next.

After seven British players won singles matches on Monday — a professional era record at Wimbledon — home fans had more to cheer on Tuesday as fourth seed Jack Draper, his nation’s big hope, avoided any dramas by easing past Argentina’s Sebastian Baez who retired hurt trailing 6-2, 6-2, 2-1.

In total, 10 British players have reached round two.

Five-times Grand Slam champion Iga Swiatek, seeded eight, has yet to conquer Wimbledon but showed positive signs when she beat Polina Kudermetova 7-5, 6-1 while Russian teenager Mirra Andreeva advanced after a 6-3, 6-3 victory over Mayar Sherif.

Both might have expected Gauff to be a major obstacle but the world number two subsided against Yastremska.

“I feel like mentally I was a little bit overwhelmed with everything that came afterwards,” Gauff said about the spell following her Paris triumph last month.

“I didn’t feel I had enough time to celebrate and also get back into it.”

The women’s draw is now without three of its top five seeds after number five Zheng Qinwen of China, the Olympic champion, suffered a third successive Wimbledon first-round defeat, beaten 7-5, 4-6, 6-1 by Czech doubles specialist Katerina Siniakova.

“I believe if I get through the first match, I will start to play better and better (on grass),” Zheng said. “The problem is the first match for me is complicated.”

Many will lament the exit of Wimbledon dark horse Alexander Bublik, seeded 28^th. The Kazakh showman is guaranteed entertainment with his array of trick shots but he was unable to avoid the exit door, as he was dragged into battle by Spaniard Jaume Munar and beaten 6-4, 3-6, 4-6, 7-6(5), 6-2.

Late in the day yet another seed fell when Frenchman Ugo Umbert was beaten by veteran countryman Gael Monfils, again defying his 38 years to edge a five-setter.

American Fritz survived, though, letting out a huge roar as he beat Perricard 6-7(6), 6-7(8), 6-4, 7-6(6), 6-4 in a match carried forward from Monday. Perricard’s consolation for losing the cliffhanger was a 153 mph serve — a Wimbledon record.

Tommy Paul took out Briton Johannus Monday with little fuss, the 13^th seed cruising through 6-4, 6-4, 6-2, but it was the end of the road for fellow American and 30^th seed Alex Michelsen who fell 6-2, 3-6, 6-3, 3-6, 7-6(6) to Serbia’s Miomir Kecmanovic.

Zeynep Sonmez became the first Turkish woman to reach the second round at the grasscourt Grand Slam when she battled past Romania’s Jaqueline Cristian 7-6(3), 6-3.

Victoria Mboko found out a few hours before she faced Magdalena Frech that she had entered the main draw as a Lucky Loser due to Anastasia Potapova’s withdrawal and the Canadian teenager rode her luck to stun the 25^th seed 6-3, 6-2.

Fourteen years after first adding her name to the Wimbledon honours board, twice champion Petra Kvitova performed her last dance on the lawns, the Czech losing 6-3, 6-1 to American 10^th seed Emma Navarro. — Reuters
