TENNIS: Bernard Tomic outfoxed ninth-seeded Frenchman Richard Gasquet on Saturday in another impressive display to reach the fourth round at Wimbledon.

Tomic, at 20 the youngest man left in the men's draw, extended his stellar run at the grass-court grand slam into a second week with a 7-6 (9-7) 5-7 7-5 7-6 (7-5) upset win.

The Australian world No.59 progressed to the last 16 at Wimbledon for the second time and he will face seventh-seeded Czech Tomas Berdych.

Another win would likely set up quarter-final showdown with top seed Novak Djokovic, the player who beat him in the 2011 quarter-finals at the All England Club.

Playing without the court-side support of his banned father and coach, Tomic seemed to lap up the big stage first-up on Wimbledon's Centre Court.

And some 15,000 supporters were treated to an entertaining match as Tomic was forced to test his full range of skills against the crafty Frenchman.

In stark contrast to his opening encounters against big-hitting Americans Sam Querrey and James Blake, this was more an exercise in tactics and touch.

Neither player broke serve in a high-quality first set, with Tomic digging himself out of several service holes to send the match to a tiebreaker.

He edged it with a remarkable forehand drop shot to take a one-set lead.

Tomic was millimetres from taking the second set.

Up 5-4, Tomic had Gasquet 0-40 on serve and the Australian missed several passing shot opportunities.

After saving four set points, the Frenchman made him pay, breaking serve in the next game and serving out the set.

The same opportunity presented itself to Tomic in the third set but this time he didn't let it slip, converting a second set point opportunity with a great forehand retrieval.

Tomic was sublime in the fifth-set tiebreaker, converting his third match point with a big serve and celebrating with his arms outstretched.

"I'm very happy. I played a very a good match and it's difficult coming out first on Centre Court,'' Tomic said.

"I was very nervous but I couldn't ask any more of myself.

"I'm happy with the way I'm going and hopefully I can keep it up.''

The victory snapped an 11-match losing streak against top 10 players on the tour.

Sam Stosur crashes out

Samantha Stosur's Wimbledon campaign ended, with 23rd-seeded German Sabine Lisicki coming from a set down to win their third-round match on Sunday morning (AEST).

The 14th seed missed a chance to reach the last 16 for the first time in her career in a 4-6 6-2 6-1 loss.

The defeat leaves Bernard Tomic as the last Australian standing in singles, after he beat French ninth seed Richard Gasquet.

Despite missing a chance to face top seed Serena Williams in the last 16, Stosur took encouragement from matching her best showing at the grand slam on her least-favoured surface.

"I would have loved an opportunity to play in the fourth round but at least today, again, I have to be happy with the way I played overall,'' Stosur said.

"There was a couple points here and there in that match and maybe it's a different story.

"I know 6-2 6-1 doesn't look that close, but I think a lot of those games were.

"So as disappointing as it is, I have to say this is probably the best I've felt walking away from Wimbledon."

Lisicki progressed to a possible fourth-round clash with top seed Serena Williams.

Stosur entered the match on Centre Court full of confidence having equalled her best performance at the grass-court grand slam with easy wins over Slovakian Anna Schmiedlova and Russian Olga Puchkova.

The 29-year-old always was prepared for a much tougher encounter against big-hitting Lisicki, a semi-finalist at Wimbledon in 2011 and quarter-finalist the past three years running.

Still Stosur started impressively, securing the first break of the game to go 2-1 up.

From there the Australian maintained a strong service game to wrap up the first set inside 28 minutes.

Lisicki lifted in the second set, breaking serve in the fourth game.

The German went 5-2 up before calling an injury timeout as she received treatment for a cut on her finger.

Stosur earned a break point the next game but Lisicki fought back to square the match at one set all.

Stosur faced a titanic struggle in her opening service game of the second set before eventually being broken.

She missed several chances to break back in the next game but fought back from 0-40 to hold serve shortly after to keep her fading hopes alive.

However, she ultimately couldn't halt a fast-finishing Lisicki, with the German securing another break and serving out the match.
