Top 5 Points from the Australian Open

Simon has a reputation for playing gritty tennis though, and he pulled it back, winning the second set with a tiebreak, with Djokovic starting to make many unforced errors.

During his post-match interview in the Rod Laver Arena, a fan shouted out to Djokovic: “No more drop shots”.

Djokovic admitted he will need to step up his game on Tuesday, when he faces seventh seed Kei Nishikori, who dismantled world No. 10 Jo-Wilfried Tsonga in straight sets earlier on Sunday.

“Well, gosh, I didn’t know she was here, I feel honored to be able to play in front of her”, Williams said.

Maria Sharapova is through to the quarterfinals of the Australian Open after a 7-5, 7-5 win over Belinda Bencic of Switzerland.

“I always try to prepare the best I can and try to play well and the results are the proof and I am going to try to do the same for the rest of the tournament”, Berdych said.

Simon would reach this stage after wins against completely unseeded opposition, while Djokovic would easily see-off Andreas Seppi in the last round to book his spot here.

Top-ranked Djokovic won 6-3, 6-7 (1), 6-4, 4-6, 6-3 in four hours, 32 minutes and will meet No. 7 Kei Nishikori in the quarterfinals.

“I made a lot of unforced errors today but nevertheless he was always fighting”.

Tuesday’s clash will be Djokovic and Nishikori’s first Grand Slam meeting since the 2014 US Open semis, when the Japanese player won in four sets to become the first Asian man to reach a major singles final.

Djokovic’s 100 unforced errors were the most startling statistic of the day.

Lleyton Hewitt’s last Australian Open is finally over after the former world No 1 and Sam Groth lost in the doubles 6-4 6-2 to North American No 9 seeds Jack Sock and Vasek Pospisil.

Serena Williams, by contrast, booked a re-match of last year’s title decider against Maria Sharapova by sweeping into the quarter-finals without having lost a set, and Roger Federer progressed nearly as comfortably to bring the day to a close.

It was hard going and compelling viewing, and Djokovic got the crucial third set in 47 minutes when Simon netted a backhand to lose his serve.

“We played in London and he kind of destroyed me”, he said.

In a high quality opening session on the main stadium court, the five-times champion’s fourth round match follows that of his counterpart in the women’s draw, Serena Williams.

The error count was largely testament to Simon’s dogged scrambling and counter-punching style, but Djokovic also shot himself in the foot repeatedly with a string of botched dropshots. “I was returning well, so that made it tough for him to have a good serve all the time”.

“He (Djokovic) has been playing a lot of good tennis again this year”.

Radwanska was 5-2 down in her deciding set against Anna-Lena Friedsam but the 21-year-old German was reduced to tears when her legs simply gave up on her, allowing the fourth seed to recover for a 6-7 (6) 6-1 7-5 victory.
