Roger Federer is through to round four of the 2016 Australian Open after beating Grigor Dimitrov on Friday 22 January. The 17-time major winner, who is looking for a fifth title in Melbourne, dropped the second set at Rod Laver Arena but recovered to win 6-4, 3-6, 6-1, 6-4 to collect the 300th grand slam victory of his illustrious singles career.

After becoming the first man in tennis history to achieve that feat, he said: "It's very exciting, I must tell you. Like when I reached 1,000 [ATP Tour wins] last year, it was a big deal for me. Not something I ever aimed for or looked for, but when it happens, it's very special. Yeah, you look deeper into it, I guess, where it's all happened and how. Yeah, so it's very nice. I'm very happy.

"That was my goal, to react quickly after the second set because I struggled a little bit, but then found my way back, then was able to take charge of the match. It was important. Conditions, again, were very different indoors than they were against [Alexandr] Dolgopolov in the second round. Even night session plays different. Just got to manage these conditions a bit. You know, I'm pleased. Wasn't easy. I didn't expect it to be against Grigor. It was a tough round, so I'm happy."

Elsewhere on a rain-affected day five, defending women's champion Serena Williams required just 44 minutes to take her formidable Australian Open record to 71-9 with a 6-1, 6-1 thrashing of 18-year-old Daria Kasatkina. Novak Djokovic needed a third-set tiebreak to defeat Andreas Seppi, while Maria Sharapova was given a stern test by unseeded American Lauren Davis before coming through 6-1, 6-7, 6-0 in a match that lasted over two hours.

World number seven Kei Nishikori beat Guillermo Garcia-Lopez in four sets and Jo-Wilfried Tsonga had little trouble in seeing off compatriot Pierre-Hugues Herbert 6-4, 7-6, 7-6. There were also third-round wins for David Goffin, Gilles Simon, Agnieszka Radwanska, Belinda Bencic and Anna-Lena Friedsam.

In the late match, Nick Kyrgios exited his home tournament with an entertaining defeat to Tomas Berdych. The controversial right-hander made his displeasure regarding the officiating known as he was beaten in four sets 6-3, 6-4, 1-6, 6-4.
