If you're a casual tennis fan, the name Grigor Dimitrov is probably most famous, in this country anyway, for upsetting Andy Murray in the 2014 Wimbledon quarter-finals.

Victory this evening would be an even larger shock - and he's made a decent start, 15-30 up on the Sinner serve.

Oh and a Sinner double fault hands Dimitrov two break points. The Italian has not been broken at all during these Championships...

Trying to think of something new to say about Jannik Sinner is genuinely quite difficult.

He has been in imperious form at these Championships.

This is, however, the first time he is facing a seeded player at SW19 this year.

Grigor Dimitrov has not had the greatest year when it comes to the majors, having to retire injured in both France and Australia.

The long legs of Jannik Sinner go in opposite directions as he's left grounded trying to reach a Dimitrov forehand out wide.

The 34-year-old is made to work pretty hard for that opening service hold - but hold he does, thanks to a sliding backhand volley winner at the net.

Grigor Dimitrov falls 0-30 in his opening service game, behind the 8-ball early doors.

Three huge serves turn things around but the Bulgarian is still taken to deuce...

World number 10 Ben Shelton speaking on court one after his fourth-round win: "It was difficult. I feel like every time I play Lorenzo Sonego, every time I need a big point he comes out with a highlight shot. Maybe it's the same vice-versa as well. It was a lot of fun.

"I'm getting very comfortable out here on court one, I love playing in front of you guys. I was told that the crowds here at Wimbledon, before I came over here for the first time, were a bit quieter but I've got to say I didn't feel that today."

On what he was telling himself before the final game: "I don't want to play another tie-breaker! I didn't want to do it, especially against a guy who is serving the way he is. Usually you don't get the same chance twice, so I wanted to make sure I capitalised on the first one at 15-40.

"I'm happy with the way I played that last game. I felt like that was my best tennis, my best returning, and that's what I'm going to need to continue in this tournament. For me to end the match with that game, it gives me a lot of confidence moving forward."

On his grass-court tennis style and his inspiration for it: "Definitely my dad. He was in the round of 16 here 31 years ago, give or take. He loved a serve and volley.

"He had a big serve, he came forward all the time and he would like to see me come forward more than I am. My argument is that I think I'm better than him from the baseline. He inspires the way that I play on grass."

A summation of those stats we spoke of.

Superb. Sensational. Superior. Sinner.

Can Dimitrov dent them? We're about to find out on Centre.

Talking of consistency… at 34 – 11 years Sinner’s senior – Grigor Dimitrov is competing in his 58th consecutive Grand Slam, the longest such streak of any active player and fifth longest in history.

But there are signs the Bulgarian bunny’s batteries are starting to run out – he’s retired injured in all four of his past Slams dating back to this stage in SW19 last year against Daniil Medvedev.

He’s looked good so far here, dropping just one set, but this test will be up a level and then some, against a man he’s taken only one set from in four successive head-to-head defeats.

His best Wimbledon run was to the semi-finals back in 2014, losing to Novak Djokovic after stunning Andy Murray in the quarters – can he roll back the years and produce another upset?

World number one Jannik Sinner has been more dominant than you might even expect of a player in that exalted position – not only has he not lost a set so far this tournament, his serve has not been broken once.

The three-time Grand Slam champion has dropped just 17 games across three straight-set victories in reaching the last 16, equalling Jan Kodes’ Open era record set way back in 1972.

A win today would earn him a seventh consecutive Grand Slam quarter-final appearance, a feat achieved by only eight other male players in the Open era.

Novak Djokovic, Roger Federer, David Ferrer, Ivan Lendl, Andy Murray, Rafael Nadal, Pete Sampras and Mats Wilander – a pretty eclectic, esteemed list the 23-year-old is aiming to join.

OK, that's six of Monday's eight singles last-16 games down - two to go.

Men's world number one Jannik Sinner faces veteran Bulgarian Grigor Dimitrov on Centre Court and five-time women's Grand Slam champion Iga Swiatek is up next on Court One against Denmark's Clara Tauson.

Andreeva played those last two games so incredibly well and refused to miss. A much deserved win for her and into another slam quarter-final.

Mirra Andreeva speaking after progressing to the quarter-finals on Centre Court: "It is something crazy. I was so nervous playing on Centre Court for the first time. I tried to not look at the Royal Box. I saw Roger [Federer] and it means a lot that you came and watched my match. I am so happy I managed to stay focused.

"I kept telling myself that I am facing break point and that helped me to stay focused. I forgot the score at times!

On her performance today: "My serve was not bad today. I won a couple of free points with my serve. I am happy that Conchita [her coach] gave me some good advice at it keeps being so effective. I am happy with the level I presented myself on the court today. I was more nervous than usual and that's why I made some mistakes that I don't usually make. I took it point by point and I am happy with how I carried myself.

On whether it was a 'golden standard' performance: "I will talk to Conchita and see what she thought, she will probably say it could have been better!"

Mirra Andreeva did a fantastic job of staying in the long rallies against Emma Navarro, winning plenty of 'Steal Score' points.

Steal Score refers to the percentage of points a player wins when they are in a defensive position - and it turns out the 18-year-old has topped the table in that department in this year's ladies' draw.

The top five Steal Scorers include:

1. Mirra Andreeva - 49%
2. Liudmila Samsonova - 49%
3. Laura Siegemund - 42%
4. Emma Navarro - 38%
5. Clara Tauson - 37%

If you wanted a reference point, the draw average is 34%.

Emma Navarro had a spell in the middle of the match but ultimately Mirra Andreeva was just too good and some of the shots in there were breath-taking.

That's a first Wimbledon quarter-final appearance secured, but who would bet against surpassing her best-ever run at a Grand Slam and going on to the final?

Lorenzo Sonego lets out a shout of celebration as he secures a big hold.

It was a nervy time for the Italian at deuce with Ben Shelton pushing for a break that would have put him through to the quarter-finals.

But Sonego dug in, served well and keeps this fourth set going.

Two sumptuous drop shots from Mirra Andreeva help the Russian into a 40-0 lead.

Emma Navarro sends a return long and the American will now serve to stay in the match.

Emma Navarro holds for the first time in this second set.

Much better from the American.

Can she put some pressure on Mirra Andreeva's serve?

Well, how about that for a response?

Emma Navarro reduces Mirra Andreeva's lead to a break in this second set.

It feels like she needs the frustration of losing her serve to come out and play with more aggression - and it worked there.

Can she keep it up?

Mirra Andreeva is running away with this.

She gets the double break and it's all of Emma Navarro's making.

The American 11th seed saves two break points before succumbing to the third.

The Russian teenager is in cruise control now.
