HE’S done it.

Roger Federer is a 20-time Grand Slam champion after defeating Marin Cilic, 7-3 6-7(5) 6-3 3-6 6-1 in an epic Australian Open final.

The man who was already considered by most as the greatest male player of all-time is now the first to that milestone, but his list of ridiculous records and insane feats doesn’t come close to ending there.

This is what Federer has achieved over his incredible career.

THE BIG ONE

Roger Federer is the first man to win 20 Grand Slam titles.

Only three others, all women, have reached that mark — Margaret Court (24), Serena Williams (23) and Steffi Graf (22), while his nearest male challenger is Rafael Nadal (16).

That means Federer has won 10 per cent of all Open Era slams.

Federer has now won 96 singles titles, with a very realistic chance of reaching an incredible 100 by the end of the year.

THE RANKING

It’s incredibly close at the top, but Federer is still the world No.2 — just.

Nadal remains the world No.1 on 9760 ATP ranking points, with his quarter-final berth being exactly what he needed to retain the top spot. Federer is on 9605.

That order could change very quickly though with Nadal needing to defend the 300 points he earned by making the final of the Mexico Open in Acapulco last year.

Federer, meanwhile, is set to play in Dubai next month where he only reached the second round last year, earning 45 points.

The ATP rankings system sees the last 12 months of events adding up to a player’s total. Therefore if Federer wins that event this year he could earn an extra 455 points, while Nadal can only earn an extra 200 (winning each event is worth 500 points).

That could prove the difference for becoming world No.1 — a ranking Federer hasn’t held since November 4, 2012.

Federer would easily surpass Andre Agassi as tennis’ oldest over number one. The American was 33 years and 131 days old when he last held top spot in 2003.

REDEMPTION: HOW FEDERER FIXED MISTAKE THAT LET NADAL OWN HIM

THE AUSSIE KING

Despite being most closely linked to Wimbledon, Federer’s numbers at Melbourne Park are arguably just as impressive.

Federer is now tied for the most Australian Open titles (six), with Roy Emerson and Novak Djokovic, while he has reached the most Australian Open finals (seven).

He has now won 94 matches at the Australian Open, as compared to 91 at Wimbledon, 82 at the US Open and 65 at Roland Garros.

Federer helped set an Australian Open record, too, but this is one he probably wouldn’t have wanted.

This was the first time in the Open Era that both the Men’s and Women’s Singles finals went the full distance (five and three sets, respectively).

THE PRIZE MONEY

Federer’s historic haul of prize money has, of course, only increased with his Australian Open win.

Although it doesn’t quite seem to have gone up too much, given the numbers we’re talking about here — he adds $AU4 million to his career total of $US111,885,682 ($AU137,971,828).

THE ELDER STATESMAN

Federer has tied the record for most Grand Slam titles won after the age of 30 (four), with Rod Laver and Ken Rosewall.

The last six Grand Slam titles have been shared between players aged 30 or older, with the last player aged younger than 30 to win a Grand Slam being Andy Murray (aged 29 years 56 days) at Wimbledon in 2016.

The longest previous streak of Grand Slam titles won by players aged 30 or older was when Laver won all four Grand Slam titles in 1969.

Five of those were wins by either Nadal or Federer, marking the third-longest streak of Grand Slam titles won by the pair. The longest was 11, between the 2005 French Open and 2007 US Open.

Cilic was the only player aged younger than 30 to reach a Grand Slam final in 2017.

By winning the Australian Open, Federer has broken Pete Sampras’ record, winning at least one major championship (a Grand Slam, Masters 1000 event or World Tour Finals) in 12 consecutive years.

He has also defended a Grand Slam title for the first time in a decade, with the previous occasion being the US Open in 2007 and 2008.
