He's been described as "a veritable block of Scandinavian ice", but in 2011 Thomas Bjørn was the hottest player on the European Tour.
The Dane won three times that year as part of his resurgence in the game. Following his victory in the Commercialbank Qatar Masters in February, Bjørn claimed back-to-back wins in the Johnnie Walker Championship at Gleneagles and the Omega European Masters at the spectacular Crans-sur-Sierre in Switzerland.
The latter triumph marked the first time in 14 years a player over 40 had won on the European Tour.
It was a dramatic transformation that began when he ended a four-year win drought with victory in the 2010 Estoril Open de Portugal, and which also saw him working through the death of his father in 2011, when he took two months off to grieve.
From 1996 to 2006, Bjørn was a dominant force on the European Tour, only once finishing outside the top 20 on the European Tour's Race to Dubai in this time.
But then he suffered a slump that saw him drop as low as 263rd on the Official World Golf Rankings.
In this time Bjørn said he fell out of love with golf and was even considering doing something else with his life.
But his career turnaround speaks volumes for the tenacity of a man whose surname literally translates to Bear.
An intense character, Bjørn admits to having an "over active mind" and finds it difficult to switch off after a round.
One of the toughest moments of his career came when he was so close to a maiden Major victory in the 2003 Open Championship at Royal St George's.
Bjørn stepped onto the 15th tee three strokes ahead of his nearest challenger, Ben Curtis. Then he bogeyed 15, took three shots to get out of the greenside bunker on 16 for a double bogey, and bogeyed 17 as well to lose by a shot to Curtis.
But Bjørn is not a man to live in the past. And he also doesn't dwell on past successes, of which there are many.
From the start of his career Bjørn made an impact when he won the European Challenge Tour's Order of Merit with record prizemoney in 1995 following his four wins that season. He then won in his rookie season on the European Tour in 1996, ending the year with the Sir Henry Cotton Rookie of the Year Award. A year later he became the first Dane to play on a European Ryder Cup team. His leadership skills have also seen him serve as a captain's assistant on the European Ryder Cup team.
Bjørn has a passion for the European Tour that is evident in his role as the chairman of the tour's tournament committee.
And his loyalty is evident in the way he speaks about his association with Callaway. "I love the people," he says of his decision to remain loyal to them for so many years.
The respect he has earned as a player is also reflected in the names of those he has beaten.
In 1998 he won the Peugeot de Espana by one stroke over Jose Maria Olazabal and Greg Chalmers. That same year he beat Ian Woosnam by a stroke to win the Heineken Classic.
In 2000 he beat Bernhard Langer by three strokes to win the BMW International Open.
In 2001 he won the Dubai Desert Classic by two strokes over Padraig Harrington and Tiger Woods.
This year Bjørn returns to Sun City for this third appearance in the Nedbank Golf Challenge and on the back of another successful season of one victory and seven top-10s on the European Tour.
