Aus Open: Federer's 300th Grand Slam win

The 17-time major winner and third seed won 6-4, 3-6, 6-1, 6-4 in two hours, 40 minutes under the closed roof on Rod Laver Arena and will face Belgium’s 15th seed David Goffin in the next round.

Roger Federer... another career milestone.

Roger Federer continued his dominance of Grigor Dimitrov with a four-set win in the Australian Open third round, marking his 300th victory at Grand Slams. The Swiss great, facing an opponent who idolised him growing up, recorded a 6-4, 3-6, 6-1, 6-4 win on Rod Laver Arena on Friday.

The 17-time Grand Slam champion is into the round of 16 in Melbourne for the 14th time in his past 15 appearances and a meeting with Belgian David Goffin awaits.

Dimitrov required treatment on his arm in the latter stages of the match, one he looked well and truly in during the opening two sets. Tournament officials had opted to open the roof on Rod Laver despite a wet day in Melbourne, only for the rain to lead to a long delay after just one game.

After splitting the first two sets, Federer managed two breaks in the third as Dimitrov's nine unforced errors hurt him, and the 27th seed was punished in the fifth game of the fourth. Federer set up a break point for a 3-2 lead and it was converted when Dimitrov sent a forehand down the line long.

Dimitrov battled in the seventh game as he forced Federer to serve out the match, but that was no problem for the 34-year-old.  

Only former women's champion Martina Navratilova (306) has managed more slam victories than the legendary Swiss.

Federer was asked about the achievement post-match and the 17-time Grand Slam winner was understandably thrilled. "It's very exciting, I must tell you. Like when I reached 1,000 last year, it was a big deal for me," said Federer, who won his first slam match at the Australian Open in 2000. "[It is] Not something I ever aimed for or looked for, but when it happens, it's very special. You look deeper into it, I guess, where it's all happened and how. So it's very nice. I'm very happy."
