Mattia Bellucci was struggling to get his first serve in earlier but seems to have found his rhythm now.

A hold to love keeps the scoreboard looking healthy.

Superb defence at the net!

Laura Siegemund is like a wall when she moves up the court and Madison Keys just can't get the ball past her.

Even from the back of the court, the German is the one who gets the ball past Keys at the net.

The oldest player left in the draw is one game away from the fourth round.

Taylor Fritz is now two sets to the good against Alejandro Davidovich Fokina on Centre Court.

The American fifth seed broke early in the set and secures it with another break of serve, gifted to him by a double fault by the Spaniard on set point.

Fritz might need some more medical attention shortly, however, to treat a blister on his foot.

Alongside plenty of action in the singles, there are also doubles matches galore at Wimbledon with the second rounds under way.

In the men's doubles, Great Britain's Henry Patten and Finland's Harri Heliovaara have cruised through to the third round with a 7-6 (8-6) 6-3 win. The second seeds saw off British duo Billy Harris and Marcus Willis in straight sets, spending just one hour and 19 minutes on court.

In the mixed doubles, there is an all-British affair on court 16 with Jamie Murray and Emily Appleton facing David Stevenson and Maia Lumsden. After stepping on to court just 52 minutes ago, Stevenson and Lumsden have already taken the first set 6-3 and they are a break up in the second set.

Madison Keys is having a torrid time on her second serve.

Laura Siegemund can seem to do no wrong out there at the moment and is playing more delightful tennis all around the court.

At least Australian Open champion Keys has got her first serve to rely on a bit.

She fends off another break point to keep herself in touching distance of 37-year-old Siegemund.

I've seen Madison Keys hit three or four of the best shots I've ever seen in women's tennis, but then I've just seen abysmal errors.

She is even missing short balls on break points. I just don't get it. If you miss a short ball, you should have to do a lap. You cannot miss those easy short balls on break point on this Wimbledon stage.

I'm pretty confident she will turn this around though...

A perfect response from Cameron Norrie.

The Briton rises to the occasion and has three break back points.

Even some of the simplest things are looking difficult for Madison Keys.

It is just relentless from Laura Siegemund, pulling the sixth seed all around the court.

Another groundstroke goes into the net from Keys and it is a fifth break of the American's serve in this match.
