After Luke Littler became the youngest world champion in darts history at the age of 17, we look back at some of the most successful teenage stars across the world of sport.
Like Littler, Becker won arguably the most prestigious event in his sport at the age of 17, triumphing at Wimbledon in 1985 as he became the youngest men's singles champion at the All England Club.
The German successfully defended his title a year later and then won it again in 1989, before ending his career with six Grand Slam titles after success at the Australian Open in 1991 and 1996 and US Open in 1989.
Becker also became world No 1 in 1991.
Brown became Great Britain's youngest Olympian and medal winner when she took bronze in the women's park skateboarding event at the postponed 2020 Olympics in Tokyo.

Brown has also won at the X Games and the park event at the 2023 World Skateboarding Championship to become the first-ever British skateboarding world champion.
Daley began diving aged seven and started competing nationally and internationally aged nine. He was Team GB's youngest Olympian at the Beijing Games in 2008, aged 14, but failed to secure a medal in the 10m or synchro events.
That year he won gold at the British and European championships - and secured gold at the world championships the following year.
He was a so-called 'poster boy' for the London 2012 Games, winning bronze in the 10m event but t wasn't until the 2020 Olympic Games in Tokyo that he finally achieved his career goal of winning an Olympic gold with his partner Matty Lee.
By the end of Ledecky's teens, she had five Olympic golds and nine world championship titles to her name.
Having started swimming aged six, she made her international debut at the London 2012 Olympics at 15 when she surprised spectators and coaches by winning gold in the women's 800m freestyle.
She won four golds, two silvers, and secured two world records when she competed at Rio 2016 four years later.
Ledecky, who is still only 27, upped her tally of Olympic medals to 14 when she picked up four at the 2024 Paris Games.
Wilfred 'El Radar' Benitez became the youngest world champion in boxing history when he beat Antonio Cervantes at just 17 in March 1976.
He turned pro at 15 and was managed by his father, Gregorio Benitez. He and his brothers Frankie and Gregory were from one of Puerto Rico's prominent boxing families, forging their success via New York City.
His 1976 win saw him claim both the light welterweight and lineal light welterweight titles.
After a record-breaking career, Pele was regarded as one of the greatest sportsmen of the 20th century.
At the age of 15, his coach told club directors in his native Sao Paolo he would become the "greatest football player in the world". A year later he was the top scorer in Brazil's national league, leading to a call-up from the national team.
At 17 in 1958, he inspired his country's World Cup win with a hat-trick in the semi-final and two goals in the final.
Gretzky debuted for the Edmonton Oilers in the 1979/80 season and became the first teenager to score 50 goals in a season. The Great One' went on to score the most points in NHL history, with his tally of 2,857 standing to this day.
He is the only NHL player to total over 200 points in one season, a feat he achieved four times.
O'Sullivan turned professional at the age of 16 in 1992, having won a match in just 43 minutes during his debut season.
A year later he became the youngest winner of the UK Snooker Championship at the age of 17 while he also secured a Masters title aged 19.
The Rocket has since become the oldest winner of each of the sport's Triple Crown events, winning the World Championship at 46, UK Championship at 47 and Masters at 48,
Characterised by his attacking style and emotional outbursts, O'Sullivan is regarded as one of the greatest snooker players of all time and now has a record 41 ranking titles, including seven World Championship wins at The Crucible.
That longevity is something Littler will surely aspire to.
