Men's defending champion Jannik Sinner and women's top seed Aryna Sabalenka both arrived at Wimbledon with question marks hanging over them but answered the doubters with contrasting first-round victories.
Italy's Sinner – playing his first match since his shock collapse and defeat in the second round of the French Open on a scorching day in Paris – was stretched to the limit by Serbia's Miomir Kecmanovic but survived, winning 4-6, 6-3, 6-7(6), 6-2, 6-3 on Monday.
Sabalenka, who left Paris in a 'deep, dark place' after losing the last 10 games of her quarterfinal against Diana Shnaider, followed Sinner onto Centre Court and breezed past Serbian qualifier Teodora Kostovic 6-2, 6-3.
While world number one Sinner, the overwhelming favourite in the absence of Spain's Carlos Alcaraz, lived to fight another day, there were some early seeded casualties.
Norway's 11th seed Casper Ruud was handed a tough draw in the shape of big-serving Pole Hubert Hurkacz and duly lost 6-4, 6-2, 7-6(7), while 12th seed Andrey Rublev was edged out in a five-set battle against fellow Russian Roman Safiullin, losing a deciding set tiebreaker 14-12 after missing two match points.
There was heartbreak too for surprise French Open runner-up Maja Chwalinska as she lost 2-6, 7-5, 6-2 to Thai qualifier Mananchaya Sawangkaew on Monday after the Pole fell and hurt herself while on match point.
Several women's seeds moved through on a day mercifully cooler than the heatwave that gripped London last week.
Japan's Naomi Osaka once again dressed to impress, walking on court in a Kill Bill-inspired white kimono and tennis shoes that shone as the 14th seed beat Elsa Jacquemot 6-1, 7-5.
American fourth seed Jessica Pegula beat Darja Vidmanova 7-5, 6-3, while newly crowned French Open champion Mirra Andreeva, seeded fifth, beat Magda Linette 7-5, 6-4.
Swiss 11th seed Belinda Bencic had far too much experience for young wildcard Mika Stojsavljevic, whose defeat was one of many on a miserable day for home players.
It was a grim day for the home nation, who failed to celebrate a single victory. Twenty-one players, including 12 wildcards, were in the first-round draw, but after Emma Raducanu withdrew with an injury on the eve of the tournament, she was followed on Monday by Jack Draper, who announced he was also pulling out with an arm injury.
Ten British players lost, including British number one Cameron Norrie, seeded 26, beaten in five sets by inspired American qualifier Michael Zheng.
Sinner's meltdown in the Roland Garros furnace against Juan Manuel Cerundolo had raised questions about his durability in long matches, but he answered those, albeit in relatively cool conditions, against Kecmanovic.
Sinner racked up his 94th Grand Slam match win, equalling the Italian record of Nicola Pietrangeli, but shed plenty of sweat and a little blood in reaching that mark, his white shoe stained red after injuring a nail in a fall.
'It was a little tight in the beginning; I didn't play at my best, but I tried to get into it,' he said. 'I'm happy I turned it around because the third set was very tough to swallow.'
