Mirra Andreeva needs to keep her cool. She's been known to throw a tantrum or two on court, but we saw what she could do at last month's French Open when she kept her emotions in check.

It looks like things could bubble over as the Russian teenager dumps her racquet by her chair.

Barbora Krejcikova takes the set as Mirra Andreeva skews a forehand wide.

The 2024 Wimbledon champion raised her game in that second set and she now has her reward.

Barbora Krejcikova guides a lovely backhand winner down the line to open up a 0-30 lead and put the pressure on Mirra Andreeva.

Andreeva then narrowly misses a backhand and Krejcikova has three set points.

You can see the different psychologies playing out in this match.

Andreeva said coming into this she was trying to keep her expectations low, but how can they when you have just won a Grand Slam?

Krejcikova said she is keeping her expectations low, but she has struggled with injuries over the past couple of years.

Dino Prizmic has just held to love to keep his meeting with third seed Felix Auger-Aliassime on serve midway through the first set.

The young Croatian leads 3-2.

Barbora Krejcikova sails through her service game to love and now has the chance to apply some pressure back on Mirra Andreeva's serve.

At 0-30 down Mirra Andreeva nails two strong first serves to draw level.

We have seen far more errors in this set from Andreeva, more so on her backhand. You can see difference between quality of her backhand in the first and the second sets.

She isn't finding the depth and the backhand down the line, which was hurting Krejcikova.

She has lost her way a little bit.

That's better from Mirra Andreeva as she works her way to 40-0 with Barbora Krejcikova unable to turn the points into rallies.

Andreeva seals the hold as Krejcikova spoons another return wide.

Krejcikova will now serve for the second set.

Barbora Krejcikova works through another game and she is now one away from levelling the match and taking this to a deciding set.

It has not been the Mirra Andreeva so far which we saw in the first set.

A little but unexpected [this turnaround] after losing a few games in a row in that first set.

Fitness-wise wise she is looking solid. Physically looking good, it doesn't look to be a weakness of hers here today.

Mirra Andreeva isn't landing the shots she was making earlier and a couple of wayward strokes offer Barbora Krejcikova a way into the game.

We go to deuce on the Russian's serve again but she gathers herself to secure the hold as Krejcikova goes into the net.

Fourth seed Jessica Pegula had clinched a tight first set against Sara Sorribes Tormo, winning the tie-break 8-6.

Both players had their serves broken three times in an inconsistent opener but American Pegula held her nerve when presented with her only set point.

"COME ON ENGLAND!"

Something you don't expect to hear at the tennis, but one man has earned himself a laugh from the crowd on Centre Court.

Mirra Andreeva isn't happy, though, and she smacks the ball into the sky after dropping serve.

Barbora Krejcikova has responded well to losing the first set where Mirra Andreeva played so well, and the Czech backs up her break in the previous game with a solid hold.

Coco Gauff, speaking after her tight three-set win over Solana Sierra: "I was just happy and proud of myself. Solana played a great match and was hitting some big shots, so felt like a lot of the time I was on the defensive, but overall just happy with my serve.

"It held up the whole match and helped me in the tie-breaker."

On how she fought back in the final set: "My coach always tells me 'remember who you are' and I think I have a high break percentage most times so when she served for the match I just reminded myself I'm a great returner as well.

"And I knew when I served, I think I saw my stats after the first or second set, I was like 92% first serves won, so I was just trying to be aggressive with my first serve and my second serves were good too.

"I was relaxed even though I was nervous most points in the match, I was just trying to be positive and I think that showed."

On it being seven years since she beat Venus Williams at Wimbledon: "It was very special. It was kind of like my breakout moment, playing against one of my idols was insane.

"Every time I walk down these hallways I get a bit of deja vu and think, if I could do that five years ago then I'm definitely a better player since then so I definitely can do it now. I have a lot of great memories here at Wimbledon and the crowd support was amazing.

"It is always an honour to play on these grounds. You feel like you play here a lot but when you look back you probably only play 11-12 times, so I just try to be grateful for it because one day I will be the one watching somebody my age playing and I will miss being out here."

Mirra Andreeva finds herself in a spot of bother but a strong first serve and some quick work at the net brings the Russian fifth seed level.

Andreeva is being put under some pressure at deuce and Barbora Krejcikova makes it count with a lovely forehand which wrongfoots the Russian and clips the baseline.
