Last eight or bust for Nishikori
Japan's Kei Nishikori has his eyes firmly fixed on finally reaching the last eight at Wimbledon.
The world number six has made the quarter-finals at the three other Grand Slams but never at the All England Club, in seven previous attempts.
"My goal is I've got to go to the quarter-finals. That's going to be my first goal," the 26-year-old said.
"Little by little I'm getting more confidence on the grass court.
"I'll play one match at a time and hope I can reach the second week."
He came from behind to down France's Julien Benneteau on Thursday and book his place in the third round.
Nishikori won 4-6, 6-4, 6-4, 6-2 on Centre Court in two hours and 36 minutes.
The 2014 US Open finalist looked briefly troubled when he lost the first set but turned it around.
"I started playing more aggressive and more solid," he said.
"It wasn't an easy match. He started well so it was a great match for me.
"I've been feeling good on grass. I started playing much better after second and third set."
Benneteau has plunged to 547 in the rankings after missing eight months of the tour last year due to abductor surgery, but got into Wimbledon on a protected ranking.
Japan's greatest-ever men's tennis player faces Russia's Andrey Kuznetsov, the world number 42, in the third round.
The pair recently clashed at the French Open, with Nishikori winning their second-round contest 6-3, 6-3, 6-3 on the Paris clay.
Their only prior meeting came on grass in England, at Eastbourne six years ago, when Nishikori retired while 6-4, 3-1 down in their round of 32 contest.
"He's a great young player. I think he likes grass. He hits very flat and also has a good serve," Nishikori said.
Kuznetsov, the Russian number one, secured his spot in the last 32 with a 6-3, 6-4, 6-4 win over Gilles Muller of Luxembourg.
Both Nishikori and Kuznetsov had their places at the Olympics confirmed Thursday by the International Tennis Federation.
Nishikori pulled out of Wimbledon last year due to a leg injury.
He is still struggling with a rib problem that forced him to withdraw from the Wimbledon warm-up event in Halle but insisted it was not causing him too much trouble in southwest London.
Nishikori remains uncomfortable playing on grass, but his respect for the history and tradition of Wimbledon is fuelling his bid to improve on a wretched record of one last 16 appearance in seven attempts.
The fifth seed's best performance at the All England Club was that lone fourth round appearance two years ago.
