Chris Goldsmith: Su-Wei Hsieh drop shot When you know it's coming but you can't do anything about it!

Pliskova saves the first with a 98 mph second serve. But Hsieh drops another disguised backhand into the corner and the Czech can't get there.

Wow! GAME ON.

Uh-oh. Hsieh has THREE break points and they have come out of nowhere.

After the second round of women's singles, Karolina Pliskova sat joint-third in the most aces table with 15 - she has added another eight so far today.

Pliskova is going nowhere. She gets a fourth break point with an excellent return but Hsieh gets lucky with a backhand slice which just skips off the surface.

Hsieh then pulls off a brilliant drop shot and a big serve digs her out of trouble. A big, big hold.

Again, Hsieh sprays slices into each corner and Pliskova's backhand droops into the cords. The Czech misses the volley at the net but Hsieh's forehand doesn't get over the other side.

Back to deuce.

Pliskova charges up to 30-0 thanks to an unforced error from Hsieh. The third seed then slumps a return into the net but brings up two break points with a decent forehand.

Hsieh saves both as she dictates the play and sends Pliskova running from corner to corner. But the Czech bites back and gets a third break point.

Well, well, well.

Argentine 26th seed Guido Pella is taking control of his match on Centre Court.

Fourth seed Kevin Anderson hadn't been broken at Wimbledon before this match and now it's happened twice in a row! An entertaining rally ends as the South African hits a forehand long, letting Pella go ahead.

The 29-year-old then holds to love against the 2018 Wimbledon finalist.

Caroline Wozniacki was upset by several Hawk-Eye rulings as she exited the competition in straight sets to Zhang Shuai earlier.

"I thought there were a few ones that I saw way differently. But it is what it is. You can't really change a Hawk-Eye call," said the Dane. "Maybe it was right. I just saw it differently.

"He (the umpire) saw it differently and the linesmen saw it differently, as well. But then again, there's nothing you can do about it. It is what it is."

Q. Did he suggest they get someone to look at it? Did he indicate to you maybe for the next match?

"That's what he said, for the next match. Well, I don't have a next match, so..."

Q. Would you like Hawk-Eye and the All England Club to look into the Hawk-Eye replays on your match?

"I mean, at this point it doesn't matter. It is what it is. Maybe the Hawk-Eye was right. Maybe I just saw it wrong. I don't know.

"But you trust Hawk-Eye normally. You trust that it tells you the right thing. Sometimes you do see the balls a little differently than what the Hawk-Eye is. At least you know, okay, you can get it out of your mind."I do believe that it was not in the ideal place today."

An eighth ace brings up 30-0 for Pliskova before Hsieh hits a nice forehand winner. The Czech breaks through the defence with a lovely backhand slice as she tip-toes towards the net.

But Hsieh, who returns with a bit of a face plant shot, then cracks a backhand down the line! Pliskova holds, eventually, with a cross-court backhand.

Hsieh slams a backhand one way, before thumping it into the other corner. Pliskova then pushes her forehand long.

Pliskova puts pressure on Hsieh's serve but the 28th seed continues to mix up the rallies. She moves up to 40-30 with an accurate forehand.

Hsieh then drops another slice but this time Pliskova reads it and comes into the net early for the pick-up. Deuce.

Not the way you would have expected the first set to go on Centre.

Fourth seed Kevin Anderson had two break points on two occasions, but it is Argentine Guido Pella who gets the first break at a crucial moment to go a set up. He didn't manage to close it out until the fourth set point though.

Get the feeling we could be in for a long one here.

Where was this in the first set from Hsieh? Soft hands and unpredictability.

That was her first break point opportunity of the match. Pliskova got a little rattled.

These two blokes have weaponry which Nelson would have been pleased to have at his disposal.

Serve is dominating in a bloody battle of a second set, just seven receiving points meaning neither has been able to wound the other.

And four of them were in the third game when Bautista Agut could not take two break points.

Done and dusted. A wonderful game from Hsieh!

That slice from Hsieh is a delight to watch! She drops another one and Pliskova doesn't even try to chase it.

A smooth drop volley takes her to 30-15 and she smashes a backhand into the corner to bring up two break points!

Hsieh's superb double-handed slice catches Pliskova out and the Czech then fires a backhand wide.

A good hold from Hsieh, who is playing some really nice tennis.

Phoebe Waller-Bridge is sat next to outgoing UK Sport chief Liz Nicholl and chair Katherine Grainger in the Royal Box, and they were having a right old chinwag as Kevin Anderson and Guido Pella warmed up on court.

Just down to the right of the Royal Box on courtside there are some other very special guests - a small group of Chelsea Pensioners, who all stand out fantastically in the crowd.

The Czech slumps it into the net and Hsieh takes advantage when Pliskova's forehand is dragged wide after another good rally.

Pliskova brings up deuce when Hsieh is pushed back and can only backhand it into the net.
