Alexander Zverev's unhappy relationship with grass courts has continued, the No.3 seed crashing out of Wimbledon in the opening round.
Zverev, who has never won a title on grass, nor gone beyond the last 16 at Wimbledon, lost 7-6 (7-3) 6-7 (8-10) 6-3 6-7 (5-7) 6-4 to Frenchman Arthur Rinderknech in a match suspended late on Monday night and resumed at a set apiece.
World No.72 Rinderknech had only previously won one match at Wimbledon in four visits, but sealed victory with his third match point.
Across the two days, the match lasted four hours and 40 minutes, and at its conclusion Rinderknech fell to the grass in joy.
Zverev was followed on court by Novak Djokovic, who looked as if he would cruise past Alexandre Muller when he won the first set 6-1 in 30 minutes.
The Frenchman had greeted the draw by posting on social media "Please No, God, Please, No, No!..." - and that assessment seemed prescient.
But he then won the second set in a 9-7 tiebreak, saving six set points on the way.
With light dimming the roof was closed. Djokovic sprinted through the next set, winning five games from 2-1 down, only delayed by medical timeouts for both players.
Muller forced break points in the fourth set but failed to take them, and the seven-time Wimbledon winner wrapped up the match 6-1 6-7 (7-9) 6-2 6-2.
Earlier world No.1 Jannik Sinner cruised past fellow Italian Luca Nardi 6-4 6-3 6-0 to line up a meeting with Australian Aleksandar Vukic.
Sinner's three grand slam successes have come on hardcourts in Australia and the US, while he has only once reached the semi-finals at the All England Club.
The man who beat Sinner in the Halle grass-court warm-up, 28th seed Alexander Bublik, had his Wimbledon challenge unexpectedly curtailed by Spaniard Jaume Munar 6-4 3-6 4-6 7-6 (7-5) 6-2.
Bublik, who went on to win the Halle title, was serving for the match at 5-4 before Munar clawed back to make it two sets apiece via the tiebreak.
The Spaniard capitalised from there with an early break in the decider.
Last year's semi-finalist Lorenzo Musetti also made an unexpected exit, beaten by Georgian qualifier Nikoloz Basilashvili.
Seventh seed Musetti, playing his first match since retiring in the French Open semi-final against Carlos Alcaraz with a leg injury, never looked settled against the world No.126 and went down 6-2 4-6 7-5 6-1.
"Really bad day at the office,'' Musetti said.
"I came here at the last minute and of course I didn't have much good feelings with my game and honestly the physical side and energy and whatever it takes to play a match like this.''
It was 33-year-old Basilashvili's first win in a grand slam since reaching the Wimbledon third round in 2022.
American fifth seed Taylor Fritz defeated France's Giovanni Mpetshi Perricard 6-7 (6-8) 6-7 (8-10) 6-4 7-6 (8-6) 6-4 in a match suspended on Monday evening with the pair level at two sets each.
Fritz faced the fastest in Wimbledon history, 153 miles per hour (246.3km/h), but won the point.
"The funny thing is, I always tell my coaches when they sometimes say maybe I should try to serve into the body ... that I think body serves are awful. I never win the point when I do it," Fritz said.
"And I sent the video (of the record serve) to my coach, saying: 'There you go. He served the fastest serve in the history of Wimbledon right into my chest, and I won the point, so there's your proof: Body serves are bad."
British hope Jack Draper went through after Sebastian Baez retired hurt in the third set. Draper was leading 6-2 6-2 2-1 before the Argentine conceded after struggling with an injury.
"I wanted to play a bit longer in all honesty," Draper said after the 74-minute match.
