Please don't call me Oliver! The British hero taking on Alcaraz

British underdog, who takes on former champion Carlos Alcaraz on centre court today, says there's one quick thing he would like fans to know - he's Ollie, not Oliver, Tarvet. "I usually only get called Oliver when my mum is annoyed at me. So you know, I try to avoid it at all costs," the 21-year-old said.

He added that when he heard "Oliver" being shouted from the stands of court four during his first-round victory on Monday, it made him think he had "done something wrong".

Fans could be forgiven for not knowing - after all, he is the world number 733 making his Grand Slam debut.

But he is unfazed by what lies ahead in the second round - namely, Alcaraz on Centre Court in front of 15,000 fans.

If the San Diego college student were to win it would mark the biggest upset in Wimbledon history. But he is choosing to see it as an opportunity not an experience.

"I don't really like the word 'experience' because I feel like then you're just there to almost just spectate; you don't really have the expectation to win," he told BBC Sport.

"And, obviously, I'm not saying that I expect to win. But at the same time I feel like I've been quietly confident this whole tournament and it's got me to where I am.

"A big thing for me is just playing the ball, not the player."

For his father Garry, it is dreamland. "What a mouth-watering prospect," he said.

"A week of qualifying, a round one win. And this is just too much. It is going to be fun because Ollie has played in front of big crowds - 700 or 800, maybe 1,000. To go in front of 15,000, that is quite a step up, isn't it?"

Ollie's mother Jennifer is a teacher and his father is a construction manager. Their family home in St Albans was very close to Batchwood Tennis Centre, where he played "five times a week".

A talented footballer and cricketer, his focus fully switched to tennis when he was a teenager. He was home-schooled for his A-Levels so he could play full-time at the Unique Tennis Academy in London.

He cites the programme as "a big stepping stone" in his development.

"I have a lot of appreciation and gratitude for what those guys did for me," he says.

Rather than going straight into the ATP Tour ranks, Tarvet decided the best option was to learn his craft in American college tennis.

Tarvet is studying for a communications and marketing degree at the University of San Diego and said he "owes a lot" to his coaches and team-mates there.

He is the latest British player to try the American college system, with others including Cameron Norrie and Jacob Fearnley.

Tarvet has earned victories in 23 of 25 matches this year, ranking him inside the top five singles players in the National Collegiate Athletic Association (NCAA) Championships.

But NCAA rules mean players are restricted in how much they can claim from professional tournaments.

Tarvet's run through qualifying to the second round means he should be taking home prize money of £99,000, which would increase to £152,000 if he beats Alcaraz.

However, he is only allowed to claim $10,000 (£7,290) in profit every year, as well as any expenses incurred during the events.

He describes himself as "fiery" on the court and during qualifying week his shouts of "Gareth!" after winning points were a particular source of amusement - and intrigue.

He would not divulge the full meaning, but hinted it was a reference to former Wales footballer Gareth Bale.

"My team-mates were laughing and they were blowing up our group chat because I was saying it," said Tarvet, who supports Liverpool.

"But [people are] going to have to wonder, I'm sorry. It's just the inside joke to keep guys accountable of their decision-making, that's all I'm going to say."
