Wow. That’s a shock! Miomir Kecmanovic wins nine points in a row to win the first set against Jannik Sinner, the defending men’s champion. Sinner’s game fell apart, with a couple of double faults while at 4-4. Plenty of errors from Sinner but Kecmanovic, the world No 50, has taken advantage.

Is a shock on the cards after Sinner’s second-round French Open exit?

Maja Chwalinska, the French Open qualifier who reached the final at Roland Garros in a stunning run last month, was knocked out of Wimbledon in the first round by Mananchaya Sawangkaew.

Chwalinska made history by becoming the first play to advance to the French Open final as a qualifier, losing to Mirra Andreeva while ranked as the world No 114 in Paris.

Due to Chwalinska’s history run, the Polish player as in the extremely rare position of requiring a wildcard to play Wimbledon but entering the draw as the 20th seed.

However, the 24-year-old crashed down to earrth as she lost 2-6 7-5 6-2 to the Thai qualifier Sawangkaew, who is ranked 164th in the world.

Chwalinska became just the second to ever make a grand slam final as a qualifier, after Emma Raducanu at the US Open in 2021.

Novak Djokovic called Serena Williams an “inspiration” as the 23-time grand slam prepares to make what he called an “epic” comeback at the age of 44.

Djokovic revealed he had seen Williams in the gym more often this week than compared to her prime and is excited to see how she performs.

“What she's doing is inspirational and it's epic. That's what I told her. I always admired her career, her journey, her story. Of course, Venus', as well.

“For her to come back after years of being absent from the tour, two children later, and to give so much effort to, not just for her own satisfaction or coming back on the tour, but also to give all of us a pleasure of seeing her back on the court - in singles as well as doubles - is remarkable.

“I told her that whatever happens, what she's doing is truly inspirational for me personally, I'm sure for millions around the world.

“I see her in the gym more than I have, I think, seen her when she was at her prime. It tells me that she really wants this to work out the best way possible.”

There were gasps round Centre Court as Jannik Sinner put a routine forehand wide, and the world No 1 was left to face two break points in his opening game against Miomir Kecmanovic.

He found a bullet serve, then a clipped forehand winner. Kecmanovic then shanked a smash and Sinner got out of trouble. He’s looking a little erratic in these early stages.

David Beckham and Mary Berry are watching on from the front row of the Royal Box. Beckham is with his mum.

Despite a warning from the umpire over mobile phone use during play the sound of a ringtone disturbs Jelena Ostapenko as she’s about to serve - although she, and the crowd, see the funny side.

Some more fierce hitting from the Latvian, and a down-the-line winner, wraps up the set. She leads Harriet Dart 6-3.

The good news for the home crowd is that Dart seems to be moving well after that early injury scare.

A roar from Cameron Norrie as he battles through a tense first-set tiebreak against qualifier Michael Zheng to win the opening set on Court No 1.

Zheng broke Norrie when he served for the set, that made it awkward in the tiebreak by saving set points. That would have been a blow to the British No 1 to lose that, but he perseveres.

It’s clear he’s landed a tough draw, though, in the 22-year-old American. Zheng is still a college student but has qualified for all three grand slams this year.

Over on No 1 Court, that medical treatment Harriet Dart received appears to have done her some good. She lost the game immediately after but has broken Ostapenko, who is beginning to be a little loose with her shots, back to 15, and now trails 4-1.

This is the moment Jannik Sinner has been waiting a year for. The defending men’s champion steps back onto Centre Court to open play against Serbia’s Miomir Kecmanovic.

It’s an honour, and tradition, for the men’s champion to open play. Sinner is the heavy favourite to win but will be playing his first match since his shock second round defeat at the French Open.

The good news for Sinner is that it’s not a very hot day in London. The heatwave has passed, and it’s comfortable.

Former French Open champion Jelena Ostapenko retains a cult following in tennis because of her meme-worthy expressions and the drama she frequently brings to the court. Up on No 1, she breaks Harriet Dart early to lead 3-0. Ostapenko is looking too powerful for Dart, who is receiving treatment on a foot injury.

Cameron Norrie is, once again, the last British No 1 standing at a grand slam after the withdrawal of Emma Raducanu. Norrie is a former Wimbledon semi-finalist and loves this tournament, reaching the quarter-finals last year where an inspired Carlos Alcaraz was needed to end his run. His is a break up on Michael Zheng, an impressive qualifier who is still yet to graduate from college.

Over on Court No 1, Harriet Dart is stepping into Raducanu’s slot. She’s got a tough first round against former French Open champion Jelena Ostapenko, who was very close to being a seed this week.
