Read how all the action unfolded below:
12.45pmGood afternoon! Sabine Lisicki and Kaia Kanepi are due to head out to Court One at Wimbledon in around 15 minutes for their quarter-final match.
12.47pmLisicki is the new favourite with the bookmakers, having beaten world number one Serena Williams yesterday. It's the second year in a row that the German has knocked out the top seed, following her victory over Maria Sharapova in 2012.
12.49pmKanepi is the only non-seeded player left in the draw, but looked in good form during her straight-sets win over Britain's Laura Robson yesterday. The Estonian's ranking tumbled earlier this year as she missed tournaments with an Achilles injury, but she's been rediscovering the form that took her to 15th in the world in August last year.
12.51pmThis will be the first time that Kanepi has played Lisicki. The pair had been due to face each other in Beijing in 2011, but Kanepi received a walkover after the German picked up an injury.
12.53pmThere was a light shower at Wimbledon earlier this lunchtime, but it looks like the rain is staying away for now, so this match should be getting underway on time. It is expected to be wet later this afternoon, so both players will be hoping to get through this match as soon as possible.
12.55pmThe winner of this match will face the winner of the first match on Centre Court this afternoon. You can follow updates of the clash between last year's finalist Agnieszka Radwanska, and former French Open champion Li Na with Sports Mole this afternoon.
12.58pmFollowing her win over Williams yesterday, Lisicki told BBC Sport: "I am still shaking, I am so happy. Serena played a fantastic match, she is such a tough opponent. It is an amazing feeling to win this match. This is such a special place for me and the crowd were brilliant to me. I gave it everything I had, I fought for every single point to try to win it somehow. I'm not thinking about the next match yet."
1.01pmThe players are just heading onto court. It's a warm reception from the crowd for both players. They'll be given five minutes to warm up before the match gets underway.
1.03pmKanepi has won the pre-match coin toss and has chosen to serve first. There are still quite a few empty seats around Court One, but now that the players are on court there are plenty of fans quickly rushing in.
1.05pmIf the Estonian wins today, it will see her reach the last four at a Grand Slam for the first time in her career. This will be her fifth appearance in the quarter-finals of a major, and her second last-eight appearance at Wimbledon.
1.07pmThis is the fourth time that Lisicki has reached the quarters at Wimbledon, the only Grand Slam which has seen her pass the fourth round. The 23-year-old was also a finalist in the women's doubles in 2011 alongside Sam Stosur, whom she knocked out in the singles draw this year.
1.09pmThe warm-ups are over, and the players are just grabbing a last-minute drink before the contest gets underway, with Kanepi serving first.
Lisicki *1-0 KanepiBREAK! Lisicki makes a brilliant return to take the opening point of the match, before a big serve from the Estonian levels the scores. Kanepi follows it up with a double fault.

Lisicki *2-1 KanepiIt's a solid service game from Kanepi, who had made a few mistakes in the opening game of the match. She places her serves out wide, leaving Lisicki stretching on her returns, taking just the one point from her opponent.
Lisicki 3-1* KanepiLisicki makes her first double fault of the match, but makes amends with a well-timed drop shot, before smashing a forehand winner past Kanepi.

Lisicki *3-2 KanepiLisicki gets down low behind the baseline to make some tricky returns and edge ahead in the game, but Kanepi ups the pace on her serve to keep herself in the set, sealing the game with another ace.
1.28pmKanepi is unlucky to be a break down, having had advantage three times in the opening game, but she's not looked like getting the break back during Lisicki's service games. There has been little between the two players so far.
Lisicki 4-2* KanepiKanepi makes a superb backhand to set herself up for a forehand winner. She attacks Lisicki's second serve trying to bring up her first break point of the match, but puts too much power on the ball.

1.32pmLisicki's serve has not been as much of a weapon as Kanepi's at the start of this match, but she has been much more accurate and consistent than her opponent, giving the Estonian few easy points, while some faults from Kanepi have allowed Lisicki to attack her second serve.
Lisicki *4-3 KanepiLisicki makes a couple of errors with her groundstrokes, forcing the ball long twice in succession, but two poor net shots from Kanepi help the German to deuce.

1.43pmSET! Lisicki 6-3 Kanepi

1.45pmThe 6-3 scoreline seems harsh on Kanepi. The two players were very evenly matched throughout, but it was just a couple of errors from the Estonian in the opening and last game of the set that allowed Lisicki to break. Kanepi had a couple of chances against the Lisicki serve, but was unable to capitalise.
1.47pmOver on centre court, it's still on serve in the opening set. You can follow updates of that clash too with Pascal Lemesre.

Lisicki 6-3 *4-2 KanepiBREAK! Kanepi is really struggling now, making some poor shot selections, allowing Lisicki to blast a couple of easy winners past her, before two careless shots to the net allow Lisicki to break. It's difficult to see the Estonian getting back into this now.

2.17pmKanepi looked like she had a chance to get back into the match when she broke Lisicki early in the second set, but seemed to lose her focus when the German broke back straight away.
2.19pmNext up for the 23rd seed will be the winner of the match currently taking place on centre court. Last year's beaten finalist Agnieszka Radwanska has just taken the first set in a tiebreak with Li Na, but the covers are on at the minute while a shower falls.
