It's the upset that's not really an upset brewing over on No2 Court, with veteran Fabio Fognini taking the first set 6-4 against Casper Ruud.
Having not played a lead-up event on grass, been ill during the French Open and generally never been one to favour playing on the green stuff, not much is expected of Ruud here.
He did manage to get past Alex Bolt in straight sets on Monday, but has fallen behind early on against Fognini.
So what of last year's semi-finalist and former world No1 Daniil Medvedev?
The Russian, watched on by compatriot Maria Sharapova from the Royal Box, kicked things off on Centre Court, and currently leads Frenchman Alexandre Muller 4-3 on serve.
Medvedev has chances to break in both of Muller's opening service games, including at 0-40, but the underdog held his nerve to hold on both occasions.
Jack Draper reckons Cameron Norrie will be fired up after surrendering his tag as the Best of Britain.
Free of injury woes, the Sutton star came into Wimbledon as the top dog nationally after rising to a career high of 28th.
As Draper’s star continues to rise, Norrie’s is flatlining and he is in danger of dropping further down the rankings if results do not improve this summer.
The pair will meet today on Thriller Thursday in one of two high-profile all-British ties.
Draper, 22, said: “We have huge respect for each other. We’ve practised together so many times. Been a part of the Davis Cup together. I wouldn’t say we’re extremely close but we definitely support each other. We definitely have a great relationship.
“It’s going to be an interesting matchup against him because we both know each other’s games. We know each other personally. It’s definitely going to be a tough match. It’s going to bring out a really good level.
"Obviously he won’t like the fact that I’m British No.1 now. I’m a lot younger. I think that creates a really healthy rivalry and environment. We’re all competitors, we’re all individuals. We want to win. We want to do the best we can. I think it’s going to be a really competitive match.”
Two-time former Wimbledon mixed doubles champion John Lloyd loves the link up between Andy Murray and Emma Raducanu.
Following the shock news, Lloyd told the BBC: "To have these two together, she idolises Andy and now she gets the chance to play with him in probably his last tournament. How special is that?
“You know how seriously he is taking that! He will have said to Emma, we are going to win this, we are not just here to have fun. We are going to win this. That is how competitive he is.
“I think they will be on the Centre Court! He wouldn’t have entered the mixed unless he was going to play the men’s doubles as well. We are going to see him.
“It’s better than nothing, it’s not obviously the singles. We would have loved to have seen play in the singles going up against some of these great players. It wasn’t to be.
“At least he is in something. He will love it. The crowd will love it. In both events he will play, he will think he can win both. That’s the way he is.”
The draw will be made on Wednesday lunchtime and the opening matches will be scheduled for Friday or Saturday – that depends on Raducanu’s singles participation.
This means if Andy and Jamie lose their men’s doubles opener with Rinky Hijikata and John Peers, then his involvement in the mixed will be the final balls he hits in anger at his most favourite tournament.
Raducanu is set to play her second round singles match against Belgium's Elise Mertens third on No1 Court this afternoon.
Should she triumph, she will be due to face either Arantxa Rus or ninth seed Maria Sakkari, who she beat on the way to winning the US Open in 2021, on Friday.
Emma Navarro is the billionaire tennis star set to make her Centre Court debut this afternoon.
The 19th seed at this year's Wimbledon Championships, Navarro will take on four-time Major champion Naomi Osaka in a hotly-anticipated second round battle.
Navarro, 23, is an emerging force on the WTA Tour, sitting at a career high ranking of No17 in the world.
Earlier this year she won her first tour level title, beating Elise Mertens to triumph in Hobart in January.
She has also earned a cool $1,074,546 (£850k) in prize money so far this year - although this figure is dwarfed by her family's existing wealth.
The talented 5ft 7in star is the daughter of American tycoon Ben Navarro.
As per Forbes, Ben is worth a staggering $1.5bn (£1.2bn) - more than Roger Federer $550m (£434m), Novak Djokovic $240m (£189m) Rafael Nadal $220m (£174m) combined.
