# Andre Agassi - 4 titles
One of the most popular tennis faces, Andre Agassi is credited with popularizing the game of tennis in the 1990s. The first player in the Open Era to win the Golden Slam (all the Grand Slams and the Olympic Games Gold Medal), Agassi is widely considered to be among the greatest returners of serve.
Coached by the legendary Nick Bollettieri, Agassi was spotted by the legendary coach when he was just 13. Under the tutelage of one of the finest coaches ever, Agassi honed his skills to perfection. Though Agassi won all the Grand Slams, he had a particular liking for the Australian Open winning it 4 times in 1995, 2000, 2001 and 2003.
# Ken Rosewall - 4 titles
Another Australian tennis great, Ken Rosewall was a formidable player in the 1950s and 1960s. What makes Rosewall's wins at the Australian Open so special is that he is the youngest and also the oldest player to win the title here. His first title came at the age of 18 in 1953. 19 years later, in 1972, he won the Australian Open at the ripe age of 38 - making him the oldest Grand Slam winner in the Open Era.
A 1980 International Tennis Hall of Fame inductee, Rosewall won a total of 4 Australian Open titles.
