MELBOURNE, AUSTRALIA – Kei Nishikori reached the fourth round at the Australian Open with a straight sets victory over Russia’s Evgeny Donsky on Friday.
Nishikori, who completed a 7-6 (7-3), 6-2, 6-3 victory in 2 hours and 6 minutes on Show Court Two to get into the last 16.
The world No. 18 will next face either Spanish fourth seed David Ferrer or Cypriot 28th seed Marcos Baghdatis in Sunday’s fourth round.
Nishikori reached the quarterfinals of the Australian Open last year, the best Grand Slam performance by a Japanese man.
Top seed Novak Djokovic didn’t get everything his own way against Radek Stepanek despite a 6-4, 6-3, 7-5 win as he advanced to the fourth round and extended his winning streak here to 17 matches.
Djokovic broke the 34-year-old, No. 34-ranked Stepanek late in each set, but was troubled at times against a wily veteran who mixed up the tempo with a lot of serve-and-volley and some unorthodox shot-making.
“Absolutely it was great. Great match and great fun,” Djokovic said. “It’s always tricky to play Radek. He’s a talented player. Skillful player.”
Told about the statistics — Stepanek won 36 of the 67 points he played at the net — Djokovic wasn’t surprised at all.
“He’s skillful on the net and he was not giving me a lot of rhythm — he was changing up the pace on the ball,” Djokovic said.
“Nowadays everything is based on the baseline. It’s nice to see somebody coming to the net.”
Stepanek had Djokovic smiling and acknowledging his winners on some points, frustrated him on others with his constant, stay-in-the-point defense, and even had chair umpire Carlos Bernardes grinning with his over-the-shoulder winner to save one match point near the end.
Djokovic, who has won the title at Melbourne Park in 2008, 2011 and last year, is hoping to be the first man in the Open era to win three consecutive Australian titles. He will next play either American Sam Querrey or Switzerland’s Stanislas Wawrinka in the fourth round on Sunday.
Angelique Kerber survived some nervous moments before fending off American teenager Madison Keys 6-2, 7-5 in their third-round match, then got to blow out the candles on a cake to celebrate her 25th birthday.
Local organizers brought Kerber a cake onto the court immediately after the match and the crowd at Rod Laver Arena sang “Happy Birthday.” She blew out the candles and said thank you to the crowd and to 17-year-old Keys.
“Madison is a great young player and it was very tough,” said Kerber, a semifinalist last year at Wimbledon. “So happy I won today on my birthday!”
Kerber will next play No. 19 Ekaterina Makarova of Russia, who advanced after a tough 6-7 (4-7), 6-3, 6-4 win over 2007 Wimbledon finalist Marion Bartoli.
In the fourth round last year, Makarova beat Serena Williams and was the first of only four women to beat the powerful American in 2012. Kerber was the last.
Fourth-seeded Angieszka Radwanska, meanwhile, won her 12th match in a row with a 6-3, 6-1 victory over Britain’s Heather Watson.
“I’m extremely happy to be playing my best tennis from the beginning of the year,” said Radwanska, who won tournaments in Auckland and Sydney earlier this month. “Hopefully I’ll play on the same level the rest of the tournament.”
Radwanska will now meet 2008 French Open champion Ana Ivanovic, who beat Jelena Jankovic 7-5, 6-3 in a matchup featuring two Serbians who were both formerly ranked No. 1.
Sixth-seeded Li Na advanced 6-4, 6-1 over No. 27 Sorana Cirstea of Romania.
