10 of sport's most successful young guns ever

After 21-year-old Jordan Spieth’s record-breaking Masters win, we run down our top 10 sports stars who made it big at an early age.

With his triumph at last weekend's Masters, 21-year old Jordan Spieth became the second-youngest player to win at Augusta, behind Tiger Woods' 1997 victory, and equalled Woods' record of finishing an incredible 18 under par.

Spieth's success at such a tender age got us thinking, which other sportspeople have had notable success early on in their careers? And it turns out, there are quite a few who made their mark even earlier than Spieth did. Here are 10 of the best.

Tiger Woods

The man who managed a Masters win even younger than Spieth, Tiger Woods was beating his dad at golf when he was just 11 years old. Although his career has faltered somewhat in recent years, his record of 14 majors wins puts him amongst the best golfers of all time.

In 1985, at just 17 years and 227 days old, unseeded German Boris Becker became the youngest ever winner of Wimbledon. He went on to become world number one, winning six Grand Slam titles in an illustrious career.

Here's the man himself looking back on his amazing Wimbledon title, which is unlikely to ever be beaten. Wayne Rooney

"Remember the name - Wayne Rooney!" This was the legendary piece of commentary that accompanied the young then-Everton striker's debut goal against Arsenal five days short of his 17th birthday.

While he's not yet gone on to completely fulfill his potential in an England shirt, he's still one of the most potent strikers the Premier League has ever seen. Relive that famous goal below.

Danny Hart

In 2011, at just 19 years old, British downhill mountain biker Danny Hart won the World Championship, trouncing the rest of the field by more than 11 seconds in one of the most incredible wet weather runs in the history of the sport.

Even if you're not a mountain biking fan, this video of Hart's quite frankly insane World Championship-winning downhill run is a must-see. Nadia Comaneci

The 1976 Montreal Olympics saw gymnastics' first ever perfect 10.0 score handed out, and it just so happens that the recipient of said score was 14-year-old Nadia Comaneci.

The Romanian went on to win three gold medals at that games alone. Watch her incredible performance below. Alan Shearer

In 1988, a 17-year old Alan Shearer marked his home debut for Southampton with a stunning hat-trick against Arsenal.

Shearer went on to score a total of 260 goals in the Premier League, making him by far and away the leading scorer in the league's history. Marc Marquez

In 2013, at 20 years old and in his first season racing in MotoGP, Marc Marquez became the youngest ever rider to win the world title. He followed that up with anther world title win in his second season of racing last year and, in all likelihood, he'll win again this year.

Watch the best of his record-breaking 2013 MotoGP debut title-winning season below. Tom Daley

The 2009 FINA World Championships saw a 15-year-old Tom Daley take the gold medal in the 10-metre platform diving event.

The fresh-faced Daley beat off competition from a host of world-class competitors to take his debut world title. Ronnie O’Sullivan

Ronnie "The Rocket" O'Sullivan was always going to be a champion snooker player. He made his first century break at the age of 10, his first maximum by just 15 and just before his 18th birthday he won the 1993 UK Championship, making him the youngest player ever to win a professional rankings tournament.

Watch the final frame of his debut World Championship victory, in which he only needed half a chance to seal the title, below. Mike Tyson

In 1986, at just 20 years, four months and 22 days old, "Iron" Mike Tyson became the youngest ever boxer to win the WBC, WBA and IBF heavyweight titles.

With Tyson's lighting fast movement and heavy hammer-blow punches, champion Trevor Berbick never even stood a chance.
