#2. Mal Anderson (1972 Australian Open)- 36 years and 306 days
Mal Anderson hasn’t been one of Australia’s absolute best tennis players during Australia’s golden age of tennis during the 1950s and 1960s especially with the presence of the likes of Ken Rosewall, Tony Roche, Rod Laver, Roy Emerson, and John Newcombe. However, he did win a Grand Slam at the 1957 US Open and reached two Grand Slam finals during his 19-year long professional career.During the 1972 Australian Open, Anderson was already in his late 30s but still had some tennis left in him. He reached the quarter-finals with ease and scripted one of the upsets of the tournament by defeating compatriot and top seed John Newcombe in an epic five-setter. In the semi-finals, he defeated fourth seed Alex Metreveli to set up a final clash with second seeded Ken Rosewall. Anderson eventually lost the match in straight sets and he would never reach a Grand Slam final again.
