For a man who has won a record 17 Grand Slam titles, there's hardly anything left to prove or achieve in the sport. But, if you're Roger Federer who just recorded his 300th win in the Grand Slam singles match, the expectations doesn't seem to end.
The Swiss ace reached the milestone at Rod Laver Arena on 22 January, when he moved into the fourth round of the ongoing Australian Open with a 6-4, 3-6, 6-1, 6-4 triumph over the Bulgarian star Grigor Dimitrov.
Federer, who became the first man to achieve the feat, is now 67 wins clear of the second-placed Jimmy Connors in the list of men with most wins in Grand Slam singles matches. He is now only behind Czech-American Martina Navratilova who leads the overall list with 306 wins in singles matches.
His latest feat has also added to the ever-growing chants of an 18th major title which has eluded him since 2012. Ever since winning the Wimbledon title in 2012, Federer has not been able to add the elusive 18th title to his decorated trophy cabinet.
The closest he came to notching up the title was last year when he was pipped by world no.1 Novak Djokovic to the Wimbledon and the US Open title.
Even if the Swiss ace fails to register his 18th major title win in the tournament, here's why he will always be considered as one of the greatest tennis players of all time:
He was named the Laureus World Sportsman of the Year for a record four consecutive years (2005-2008).
He has also reached each of the four Grand Slam finals at least five times - an all-time record. In Wimbledon, he has played a staggering ten finals.
He has won a record six ATP World Tour Finals, playing in the finals at all nine ATP Masters 1000 tournaments (a record shared with Novak Djokovic and Rafael Nadal).
He is among the seven men (and among four in Open Era) to record a career Grand Slam. He also shares an Open Era record for most titles at Wimbledon with Pete Sampras (7) and at the US Open with Jimmy Connors and Sampras (5).
He has been ranked among the top 8 players in the world continuously since 14 October, 2002.
He has won the ATPWorldTour.com Fans' Favourite Award a record 13 times consecutively (2003-2015) and the Stefan Edberg Sportsmanship Award (voted by the players) a record 11 times (2004-2009 and 2011-2015).
The Swiss ace has won a record 17 Grand Slams including four Australian Open, one French Open, seven Wimbledon and five US Open titles.
He has appeared in 18 of the 19 finals from the 2005 Wimbledon through to the 2010 Australian Open.
He has played in the semifinals at 23 consecutive Grand Slam tournaments, from the 2004 Wimbledon Championships through the 2010 Australian Open.
He has played in a record 27 men's singles Grand Slam finals, including 10 in a row from the 2005 Wimbledon Championships to the 2007 US Open.
He is the first-ever player to record 65+ match wins at each of the four Grand Slam tournaments.
He also holds the record of maintaining the world No. 1 position for 302 weeks (including 237 consecutive weeks).
