Francesca Jones was broken twice in the second set but comes out fighting in the decider.

A hold to 15 is just the way to get going.

Georgia's Nikoloz Basilashvili has completed a shock 6-2 4-6 7-5 6-1 win over Italian seventh seed Lorenzo Musetti. After losing the opening set, the Italian looked to be turning the tide in the second, but lost his way again in the third and fourth sets.

Alexander Bublik was unable to fight back from a set down against Spain's Jaume Munar on court 14. It wasn't plain sailing for the Spaniard though, who needed five sets and over three hours to see off the 28th seed 6-4 3-6 4-6 7-6 (7-5) 6-2.

The upsets don't stop there though, as reigning Olympic champion Zheng Qinwen has also been stunned out on court in SW19. Katerina Siniakova came out on top over three sets, beating the fifth seed 7-5 4-6 6-1 on court three.

Wang Xinyu also managed to get the better of 15th seed Karolina Muchova on court 15. The Chinese player only needed one hour and 25 minutes to complete the straight-set victory and cruise through to round two.

Elsewhere, seventh seed Mirra Andreeva has opened up a one-set advantage over Egypt's Mayar Sherif. The pair are into the second set on court three, which Andreeva leads 2-1.

Tomas Machac already has one foot in the second round after opening up a 6-3 6-2 advantage over Bosnia-Herzegovina's Damir Dzumhur. He is already 2-0 up in the third set on court 15.

Arthur Rinderknech produces a brilliant passing shot with Alexander Zverev at the net to earn a set point, and Zverev's forehand clips the top of the net before sailing just long...

Rinderknech takes the third set and a 2-1 lead in this first-round match.

Third seed Zverev is in danger of an early exit.

10th seed Emma Navarro breaks for a second time to take control of this first set.

Emma Navarro is on top now.

The American takes the lead for the first time in this set as Petra Kvitova takes her unforced error count to 12 so far with a couple of ill-judged shots.

At 35, Dan Evans might not have too many more Wimbledon appearances left and you can see just how much it means to remain in the mix this year.

Evans heads off to the side of the court cheering and then starts throwing all sorts of equipment - towels, sweatbands and balls - into the crowd.

Arthur Rinderknech, the world number 72, has served his way through the third set with very little alarm since that early break and it means Alexander Zverev must hold serve to stay in it.

It's poor from Petra Kvitova.

The Czech hits three consecutive double faults, allowing Emma Navarro her first break point of the match without hitting a shot in the game.

The American makes no mistake to level up at three games apiece.

Dan Evans cuts a shot just over the net and it kisses the paint to get him to 15-15. Jay Clarke asks for a review and it's clearly in - we have electronic line calling now so it's a little pointless.

Evans kicks on further and has two match points.

Petra Kvitova, who will retire after the US Open later this year, seems like she's in a hurry.

She's hit some brilliant winners so far - 10 in total - but there was a couple of wild unforced errors in that game that let Emma Navarro off the hook.

It's clear that the Czech doesn't want to get into long rallies with her American opponent.

Harry Poole
BBC Sport at Wimbledon

Daniil Medvedev and Alexander Bublik both out?

It was the other Harry Poole who wrote that five men’s players to watch at Wimbledon preview piece, I swear…

Despite his loss, Bublik takes the time to stop for photos as he attempts to escape court 14, which is completely crowded at all sides after more and more spectators caught wind of a five-set showdown.

Not his day.

A little embarrassing for Jay Clarke but he recovers to eventually get the hold.

Dan Evans will serve for a place in round two.

Jay Clarke pops up with an ace for advantage.

Oh. Clarke attempts an underarm serve but it goes horribly wrong and doesn't make it over the net.

Clarke goes on to double fault and it's third deuce.

Dan Evans slips when trying to return Jay Clarke's serve and it's straight into the net.

But a wonderful passing shot takes it to second deuce.

Dan Evans ends up behind the barrier off the side of the court as he goes chasing the ball - he isn't successful with the return and trails 40-15.

Evans fights back to deuce.

Simple as you like for Petra Kvitova, who is keeping the rallies short and overpowering Emma Navarro.

She finishes this game within three minutes to restore her break lead.

Yuliia Starodubtseva has been demonstrating that she's back in this match after holding serve and saving two break points.

Some deep breaths by both players as this match continues to heat up.
