Mats Wilander is a former World No. 1 tennis player from Sweden. From 1982 to 1988, he won seven Grand Slam singles titles, and one Grand Slam men's doubles title. In 1988, Wilander won three of the four Grand Slam singles events and finished that year ranked World No. 1. Although he never won the singles title at Wimbledon, Wilander twice won the Australian Open when that tournament was still played on grass courts. This makes Wilander one of only five men to have won Grand Slam singles titles on grass courts, hard courts, and clay courts. He and Rafael Nadal are the only men in tennis history to have won at least two Grand Slam singles titles on each of the three surfaces. Wilander won his fourth Grand Slam singles title at the age of 20, the youngest man in history to have achieved that feat. In addition he also won eight Championship Series titles the precursors to the current Masters 1000. He won 33 singles titles and seven doubles titles during his career. He was also a driving force behind Sweden's run of seven consecutive Davis Cup finals in the 1980s.
