Pliskova 6-3 2-6 3-1 Hsieh*
This is wonderful tennis.
Hsieh sends Pliskova into the corner and volleys at the net to save the first break point. The Czech then slips and Hsieh can just parry it into the open court.
One left...
Anderson 4-6 3-6 0-0 Pella
Kevin Anderson came from two sets down in the Wimbledon quarter-final last year.
And he did it against none other than Roger Federer, so this isn't all wrapped up for Guido Pella yet.
Pliskova 6-3 2-6 3-1 Hsieh*
Rally of the day!!! Both players are scrambling before Pliskova eventually lobs it past Hsieh, to huge applause from the crowd.
The Czech then picks off another slice at the net and boxes off a low forehand. Three break points!
Pliskova takes the point after a superb rally in her match against Hsieh
Pliskova 6-3 2-6 3-1 Hsieh*
The first is saved when Hsieh goes long before Pliskova smashes an overhead volley into the corner in style.
She takes advantage with - you guessed, an ace - and superbly picks up a slice at full stretch. Pliskova walks back to the baseline with a huge grin on her face.
Anderson 4-6 3-6 Pella
What a performance from Guido Pella!
Fourth seed Kevin Anderson cannot return his serve out wide and now the Argentine is a set away from being in the fourth round of a Grand Slam for the first time.

Pliskova goes for the serve down the T but Hsieh picks it off with a wonderful backhand return. The Czech catches the cords but Hsieh's lob then drops long.
Hsieh has two break points though, when Pliskova slumps it into the net again.

That was a fantastic reaction from Pliskova. It showed how much she wants this.
She was one from seven regarding break points, she finally gets another.
By adding former champion Conchita Martinez to the group, five or six details can make the difference.
Anderson 4-6 3-5 Pella*
Another game, another break on Centre.
Kevin Anderson looks hesitant at the back of the court and hits a forehand into the net to give Guido Pella break point.
The Argentine lobs fourth seed Anderson (no easy feat, he's 6ft 8in!) and the South African's return is wide.

Oh dear. The Croatian-Slovakian pairing of Ivan Dodig and Filip Polasek get the break in the fourth set. Jamie Murray and Neal Skupski have some work on to stop this heading to a fifth set...
*Pliskova 6-3 2-6 2-1 Hsieh
Pliskova lets out a huge roar as she gets the break with a thunderous forehand winner.
Pliskova 6-3 2-6 1-1 Hsieh*
Pliskova keeps her momentum and picks off Hsieh's serves to go 30-0 up. The 28th seed mixes it up and drops another slice to draw level but invites Pliskova to slam a backhand into the corner to pick up a break point.

Joel Newnham: With Anderson struggling a bit, who can challenge Djokovic in this half?
Pliskova 6-3 2-6 1-1 Hsieh*
Hsieh has her slice, Pliskova has her serve.
She's up to 30-0 with a few big hits and drops an ace to go 40-15 up. But a double fault follows...
The Czech holds her nerve and smashes a 10th ace down the T. Unreal!

Hsieh's drop shot is like dynamic to Pliskova. Once they are lit, there is no touching them.
She's up to 40-15 and holds when Pliskova's superb return is picked off and sliced into the far corner.
Murray/Skupski 6-2 6-7 (2-7) 6-3 1-1 Dodig/Polasek*
British duo Jamie Murray and Neal Skupski are up and running again on court 18.
They had a two sets to one lead at the close of play yesterday.
It's on serve in the fourth against opponents Ivan Dodig and Filip Polasek, despite Muzza and Skuppa having to fend off break point a moment ago to hold.

That's really what's turned the match around... Hsieh throwing different angles of slices. If she can start dictating play...
With the variation from Hsieh, Pliskova is making a lot more unforced errors.
Pliskova 6-3 2-6 Hsieh
Hsieh has saved six out of seven break points in this match. Five of those came in that second set.

BBC Sport at Wimbledon
Anglo-Russian relations aren't strained at Wimbledon. That's judging by the fact Khachanov is receiving most of the support on court two.
The fans have got the Russian 10th seed's back when he argues a code violation given by the umpire by bouncing his frame off the hallowed turf. Not here, young man.
And the mood turns sourer as Bautista Agut then races away with the tie-break.
A long way back for 23-year-old Khachanov if he is to stick his name in the Wimbledon last 16 for a second time and equal his best run here.
Khachanov surprised to receive a code violation for bouncing his racket
Pliskova 6-3 2-6 Hsieh
Court One are being treated to some brilliant tennis here. There's a bit of movement at the end of the set but plenty are sticking around - they don't want to miss a thing!
*Anderson 4-6 2-3 Pella
Maybe Anderson and Pella are spurred on by a watching Spice Girl, because this is turning into an exciting match on Centre.
Both players are bringing their A-game, but Pella takes a slight dip as he fluffs a backhand volley to put things back level.
