Kelly Slater is an 11-time ASP (Association of Surfing Professionals) world champion. He’s the youngest (at age 20) to accomplish this, and also the oldest (at age 39, in 2011).
I was wondering about comparable achievements in other sports.
Gordie Howe won the Stanley Cup in 1950 with the Red Wings, at age 22, and won the Avco Cup in the WHA in 1975 with the Houston Aeros, at age 47. I have to believe that younger players have been on Stanley Cup winners, but I’d be surprised if any older players were on a championship team.
Jack Nicklaus was both the youngest and oldest golfer to win the Masters, at ages 23 and 46, until Tiger Woods won it at age 22. Jack is still the oldest.
Al Oerter was the youngest champion in the Olympic discus throw. I’m not sure if he was the oldest, but he won 4 consecuitve gold medals, so he MAY have been.
Boxing -Mike Tyson was 19 when he took the belt
MMA - Jon Jones Light-Heavyweight champ 23 years old
George Foreman wasn’t quite the youngest heavyweight champ, at 24, but he was the oldest at 45.
The first champion in any given sport held both titles at least briefly.
tres sage
Tennis star Ken Rosewall was both the oldest and the youngest man to win the singles title at the Australia Open.
He won it first as an 18 year old amateur, later as a 37 year old pro.
Donald Rumsfeld was both the youngest and the oldest champion of the Department of Defense.
