At the Australian Open in the new century, the top four seeds swept into the semifinals four times, with only one instance where the world number one failed to advance!

The Australian Open has concluded, but the analysis around it continues. How successful was this year's men's singles tournament? This marks the fourth time since the 21st century began that the top four seeds all reached the semifinals of the men's singles. So, what were the outcomes of the previous three occasions? Let's take a look at the match scores from those times.

2005 Australian Open

Semifinals: [4] Safin 5-7, 6-4, 5-7, 7-6(6), 9-7 Federer [1]

This is one of the most famous matches in Grand Slam history, fittingly taking place at the centennial Australian Open. Ultimately, facing then world number one and reigning champion of all Grand Slams except the French Open, Federer, the Russian Tsar Safin took huge risks and managed to dethrone the emperor in a tightly contested five-set battle, pulling off an upset comeback.

Semifinals: [3] Hewitt 3-6, 7-6(3), 7-6(4), 6-1 Roddick [2]

The other semifinal featured the home favorite against the previous year's year-end number one. Although less intense than the other match, it still included two tiebreaks, with the home crowd's support helping Hewitt to a superior performance.

Final: [4] Safin 1-6, 6-3, 6-4, 6-4 Hewitt [3]

This final closely resembled this year's event, where the eventual champion lost the first set but rallied to win the next three. Although Safin only won two Grand Slam titles in his career, this Australian Open victory is highly prestigious.

2012 Australian Open

Semifinals: [1] Djokovic 6-3, 3-6, 6-7(4), 6-1, 7-5 Murray [4]

Semifinals: [2] Nadal 6-7(5), 6-2, 7-6(5), 6-4 Federer [3]

This time, the Big Four all made it through. Djokovic and Murray battled through a full five sets again, with the defending champion narrowly prevailing; Nadal once again defeated Federer at the Australian Open, demonstrating his formidable hard-court skills.

Final: [1] Djokovic 5-7, 6-4, 6-2, 6-7(5), 7-5 Nadal [2]

The final was a showdown between the titans Djokovic and Nadal. The historical significance of this match needs no elaboration — their record for the longest Grand Slam singles final remains unbeaten, and the award ceremony afterwards has become an eternal classic in tennis history.

2013 Australian Open

Semifinals: [1] Djokovic 6-2, 6-2, 6-1 Ferrer [4]

Semifinals: [3] Murray 6-4, 6-7(5), 6-3, 6-7(2), 6-2 Federer [2]

The two semifinals displayed contrasting scenarios: Djokovic easily defeated another Spaniard, Ferrer, while Murray once again proved his 2012 US Open victory was no fluke. Despite losing two tiebreaks, he triumphed over Federer in a five-set thriller.

Final: [1] Djokovic 6-7(2), 7-6(3), 6-3, 6-2 Murray [3]

The final followed a familiar script. Djokovic defended his Melbourne crown once more, while Murray was forced to accept another runner-up finish on Australian soil.(Source: Tennis Home)
