Two-time Wimbledon champion Petra Kvitova, who has won 27 singles titles on the WTA Tour, is writing a column for the BBC Sport website during the championships at the All England Club.

The 29-year-old Czech, who before this week had not played since pulling out of the French Open in May with an arm injury, beat France’s Kristina Mladenovic 7-5 6-2 in the second round on Thursday.

I now have some better memories of Court One at Wimbledon.

Last year, I lost to Aliaksandra Sasnovich in the first round on that court and I didn’t want the same thing to happen again.

I started off a bit tired and nervous against Kristina Mladenovic, maybe because of last year, but I was happy that I was able to turn the first set around and that I kept playing well after that.

I was also reminded of some nice memories on my way to the court when I saw some photos on the wall from when I won my first Wimbledon in 2011, which I had not noticed before.

It’s taken me a while to get into the third round here again. I haven’t been here since 2015, which was before my ‘second career’ – as I call the time after the attack. I will do my best in the next match against Magda Linette, and I am just so glad to still be in the draw.

It will be a difficult match against Magda, who I beat three years ago in Montreal, and I just need to be ready and healthy. I will have another day off on Friday, where I will go to the gym but definitely not hold the racquet.

Strawberries and (a little bit of) cream

I always stay in Wimbledon village every year. I love going to the restaurants there and the shops.

I love sushi and eat a lot of it during tournaments, and I really like Italian too. If I have time, I will sometimes go for a manicure or pedicure in the village.

I rent a house rather than stay in a hotel, and I always stay in a different one. It’s very nice and relaxing there; it’s like staying at home. Sometimes my team have barbecues at the house in the back garden.

I have been to see Big Ben and had a walk near the London Eye.

One of the main traditions I like to do when I am here is to have strawberries and cream. And yes, I’m allowed the cream! Just a little bit, of course.

I’ve also been following some of the other tennis results, like Coco Gauff. She is playing very well and it’s great to see someone so young going deep into the tournament.

‘Matches are my way of training’

I’m a player who doesn’t really need too many practice sessions at Grand Slams, especially when I’ve had a really big injury to my forearm that meant I didn’t know if I could play here at all.

It is a good way to do it. I’ve done it many times in the Grand Slams, where I have days off with no hitting – I am used to it. And so I will have another day off on Friday.

For me, it’s just enough to play in a match. Matches are training enough – the longer they go on, the better it is since I haven’t trained as much.

When the match gets longer, I play better.

Petra Kvitova was speaking to BBC Sport’s Sonia Oxley at Wimbledon.

Andy Murray’s Wimbledon return began in ideal fashion as the Briton and his partner Pierre-Hugues Herbert thrilled the home fans with a late-night comeback win in the men’s doubles.

Murray and Frenchman Herbert won 4-6 6-1 6-4 6-0 against Marius Copil of Romania and France’s Ugo Humbert.

The first-round match finished at 21:22 BST on Thursday in front of a sizeable crowd under Court One’s new roof.

“It was great to get the win and a nice atmosphere,” said Murray, 32.

“I was a little bit nervous at the start but we got better as match wore on.”

Fittingly, it was Murray who clinched the match with an overhead volley, warmly embracing Herbert before breaking out into a beaming smile as he took the acclaim of the jubilant British fans.

Scot Murray and Herbert will play Croatian sixth seeds Nikola Mektic and Franko Skugor next, with Murray’s older brother Jamie and fellow Briton Neal Skuspki potential third-round opponents.

Murray and Skupski were forced off court because of the light when they led 6-2 6-7 (2-7) 6-3 against Croatia’s Ivan Dodig and Filip Polasek of Slovakia.

Murray revels in Wimbledon comeback

Two-time singles champion Murray pulled out on the eve of the tournament 12 months ago, hampered by the pain in his hip which eventually led to a resurfacing operation in January.

He broke down in an emotional news conference at the Australian Open earlier that month, fearing the operation might force him to retire from an illustrious career which has also brought him a US Open title and two Olympic gold medals.

But here he was – 723 days since his last appearance when he lost in the 2017 quarter-finals to American Sam Querrey – rid of the pain and heavy limp which hampered him before he had the operation with Royal surgeon Sarah Muirhead-Allwood in January.

The former world number one returned to competitive action in the doubles at Queen’s in June, going on to win the title alongside Spain’s Feliciano Lopez.

Murray described the feat as “mental”.

At Wimbledon, he has linked up with Herbert – a doubles expert who has won all four Grand Slam titles – in the men’s event, and is playing with American 23-time Grand Slam champion Serena Williams in a blockbuster partnership in the mixed.

The pair started slowly in a first set where Murray struggled to land a first serve, which contributed heavily to his team’s low first-serve percentage of 45%.

But they grew in rhythm and understanding as the match wore on, breaking six more times as their service games improved to complement their sharp play around the net.

With his wife Kim among the crowd, Murray began to enjoy himself and showed glimpses of his best shot-making with a couple of stunning backhand winners.

Darkening skies meant the new roof came into use for the second time before the fourth set began at 20:50, the brief break not halting the progress of Murray and Herbert as they raced away with the match.

“That’s the one thing that’s nice about the five-set doubles format, you have time to work things out,” Murray said.

“Whereas with the sudden death deuce, like when I played with Marcelo Melo in Eastbourne last week, we didn’t have any time to get used to each other.

“Here I think that was the case, and we got better as the match went on.”

‘Jamie is the number one son’ – Andy jokes about mum watching his brother

Murray’s match had not been assigned to a court as Wimbledon organisers waited to see how the day’s play on Centre Court and Court One panned out before making a decision.

And once Murray’s mixed doubles partner Williams edged past 18-year-old Slovenian qualifier Kaja Juvan, it was announced the returning Briton would shortly appear on Court One.

That drew raucous cheers when the news was delivered over the public address system, with another cacophony of noise when Murray walked out at about 18:45 and those reactions continuing throughout the match until it came to the conclusion which virtually everyone watching wanted.

But one person was not able to watch the match live – Murray’s mother Judy, who was watching eldest son Jamie’s match on court 18.

“Jamie is the number one son,” joked Murray. “He used to get all the good presents. I got like the hand-me-downs always since we were young, so I’m used to that!

“Obviously when the schedule is like that, she can’t watch both. She can’t be in two places at once.

“There’s many times here when she’s been watching Jamie’s doubles, rushed over to watch my singles. Vice versa.

“Maybe they can do my mum and dad a favour and put us on at slightly different times.”

‘An irresistible pair’ – analysis

BBC tennis commentator Peter Fleming

Copil and Humbert certainly started out as a confident pair. They were terrific in the first set.

But Murray and Herbert managed an early break in the second and, from then on, they were an irresistible pair.

In the end, Copil and Humbert had no answer.

Seven-time Wimbledon champion Serena Williams recovered from being a set down to beat teenage qualifier Kaja Juvan and reach the third round.

Williams was surprised by the 18-year-old world number 133 from Slovenia, who twice broke serve to win the first set.

The 11th seed, 37, responded to take control in the second and eventually closed out the decider for a 2-6 6-2 6-4 victory in one hour 36 minutes.

“She played well and I started out a little slow,” said the American.

“I like the pressure. I would rather be in this position than any other and I play best when I am down sometimes. I am a fighter.”

Williams, who last won Wimbledon in 2016, will face German 18th seed Julia Gorges in the third round.

She is looking to equal Australian Margaret Court’s all-time record of 24 Grand Slam singles titles but has struggled with a knee injury this year.

The American saw off Italy’s Giulia Gatto-Monticone in straight sets in the opening round but was given a sterner test by a player who was not born when she claimed the first of her 23 major titles at the US Open in 1999.

Williams lost her opening service game of the match and slipped 0-3 behind, before sending a smashed overhead volley into the net on set point as Juvan clinched the opener in 27 minutes.

Williams recovered to dominate the second set as her opponent, who beat Czech Kristyna Pliskova to reach the second round of a Slam for the first time, appeared to tire.

After twice breaking in the final set, Williams looked to be in full control and served for the match at 5-2 – only for the resilient Juvan to respond with a break of her own.

But the Slovenian was unable to stop an ace on match point and Williams sealed her progression.

Williams will now begin her mixed doubles campaign alongside former British number one Andy Murray on Friday.

“I am excited to play with a British icon like Andy,” she said.

“It’s going to be incredibly amazing and I feel honoured to share the court with him. Maybe I can learn a thing or two.”
