#1 Becoming the oldest Australian Open champion
As of now, the record belongs to former Australian player Ken Rosewall who claimed the Grand Slam back in 1972 at the age of 37 years and 62 days. However, if Federer – who is currently above 38 years of age – goes on to win the title, he will become the oldest Australian Open champion in the history of the competition and will also be the oldest Grand Slam winner in the history of tennis.
#2 Equaling most Grand Slam title wins
A win in Melbourne will bring him on equal terms with Federer and the Spaniard can then target a new record in the French Open later this year which is played on his favourite clay court where he has already won 12 Grand Slams in his career.
#3 Joint-most Australian Open wins
As of now, the Swiss star has already won the Grand Slam six times in his career and is only one-behind the most successful player in the competition’s history – defending champion Novak Djokovic. Therefore, if the 38-year-old went on to clinch the title, he will be equal with Djokovic as the most successful player in the history of the tournament with seven wins each.
#4 Qualifying for most Australian Open finals
As of now, both Novak Djokovic and Roger Federer are equal with seven finals each and both players will be eager to make it eight which they can do in the upcoming edition of the competition. Djokovic has won all of his finals whereas Federer has won six and suffered a rare defeat. However, surprisingly, both players have not faced each other in the final of the competition despite dominating it for a good part of the last two decades.
#5 Achieving second-most final appearances at Australian Open
This is a record which can only be achieved by Spanish tennis star Rafael Nadal. The world No.1 currently has the record for joint second-most appearances (5) in the final of the Australian Open with Britain’s Andy Murray and Sweden’s Stefan Edberg. However, if Nadal went on to qualify for the final this year, he will then have the second-most appearances in the final of the competition behind the likes of defending champion Novak Djokovic and Swiss tennis star Roger Federer.
