#3 Mats Wilander
Mats Wilander is one of only four men in the history of tennis to have won a Grand Slam tournament on four different surfaces. Although he never won Wimbledon, Wilander won the Australian Open during the time when the tournament was played on grass.
A gifted teenager, Wilander peaked very early in his career, winning a total of four Grand Slam titles before turning 20 - an all-time record which still stands. Apart from seven Grand Slam singles titles, Wilander also won 8 Grand Prix Super Series titles - the precursor to the modern ATP Masters 1000 tournaments.
Wilander was one of the last Swedish players to be ranked World Number 1, before Stefan Edbergand he played a key role in Sweden's run to the Davis Cup final on seven different occasions through the 1980s.
In his 15-year career, Wilander accrued just under 8 million USD in prize money. He was inducted into the International tennis Hall of Fame in 2002.
