Wimbledon set to crown a first-time women's champion as outsiders continue to propser Wally Masur gives his views on the main talking points form Day Eight at Wimbledon. WIMBLEDON will have a first-time grand slam champion after the sport's under-class completed an All England Club purge, leaving Sabine Lisicki, Kirsten Flipkens, Marion Bartoli and Agnieszka Radwanska to scrap over the spoils. In a bookmakers dream, Poland's world No 4 Radwanska will face Germany's 23rd-ranked Lisicki tomorrow night for the right to face France's world No 15 Marion Bartoli or Belgian 20th Kirsten Flipkens in Saturday's final. It is the first time in the open era (since 1968) that no previously crowned women's champion had reached the last four at Wimbledon. The 2010 French Open was the last time four undecorated players reached the last four - eventual champion Francesca Schiavone, Sam Stosur, Jelena Jankovic and Elena Demientieva. Flipkens captured the mood after another extraordinary and tumultuous day at the citadel of the sport. "It's ridiculous," she beamed. I really can't believe it. I am so, so happy, you cannot imagine. Nurtured by compatriots and former stars Kim Clijsters and Justine Henin, Flipkens put 2011 champion Petra Kvitova to the sword 4-6 6-3 6-4. Kvitova was treated on court for a fever, but had no answer to the athleticism of a rejuvenated player ranked 157th in the world a year ago. Germany's Sabine Lisicki reacts as she wins her match against Kaia Kanepi of Estonia to reach the semi-finals at Wimbledon for the second time in her career. Bartoli, playing with more freedom since teaming up with Amelie Mauresmo and Bernard Tomic's former hitting partner Thomas Drouet, overwhelmed American Sloane Stephens 6-4 7-5, A finalist here in 2007, Bartoli was jeered after refusing to continue playing when court one was dampened by rain. "It is such a pleasure to be back in the semi-finals again," she said after sharing eight consecutive service breaks with Stephens in the second set. Stephens, reputedly Serena Williams' heir apparent, claimed a meagre five points on serve in the second set, having captured one of 17 at her lowest ebb. Radwanska, eclipsed by Williams in last year's final, suffered through a remarkable last-game choke before reaching the semi-finals - but not before needing eight match points to eliminate Li Na 7-6 (7-5) 4-6 6-2. Radwanska had both legs covered in tape. "I was really struggling with that (leg soreness) today," she said. But this is the quarter-final of the grand slam, so I was really pushing myself, even 200 percent to play til the end, fight til the end. Poland's Agnieszka Radwanska throws her arms in the air as she celebrates beating China's Li Na in their women's singles quarter-final match on day eight of the 2013 Wimbledon Championships tennis tournament. Just very happy that I did it. Lisicki was the most impressive of the four winners, outclassing Estonian Kaia Kanepi 6-3 6-3, narrowly beating the rain by scooting into the last four in only 64 minutes. Ranked 24th in the world, Lisicki endured none of the drama to afflict Radwanska, Bartoli or Flipkens. Superior already at the 127th championships to world No 1 and defending champion Williams and 14th seed Sam Stosur, Lisicki again showed tremendous grasscourt prowess. The powerful right-hander unleashed 23 winners and four aces, while restricting Kanepi to 13 winners and three aces. Lisicki built pressure from the outset, breaking serve on four occasions while lapsing only once on her own delivery. "It's so nice to be back in the semi-finals," she said. I've done it before in 2011 (losing to Maria Sharapova). Marion Bartoli of France returns to Sloane Stephens of the United States during their Women's singles quarterfinal match at the All England Lawn Tennis Championships. There's no pressure on me. For me, despite being in the semi-finals, it's still the same. This is a game I love so much and I want to keep it that way. I'm going out there in every match to win it. Kanepi lamented inconsistency. "I didn't play that well today, but she played well," Kanepi said. I thought if I tried to attack in previous matches I hit winners and did well, but today I was missing a lot. But on grass there is no Plan B. I just have to go for my shots. If there is a ball, I have to hit it. Li should have beaten Radwanska in straight sets. She blew a priceless opportunity, squandering four first set points, having served for it at 5-4. US player Sloane Stephens returns against France's Marion Bartoli during their women's singles quarter-final match on day eight of the 2013 Wimbledon Championships tennis tournament. The French Open winner had no solution to beguiling Radwanska's magic - a style described pre-match by nine-time Wimbledon champion Martina Navratilova as "death by a thousand cuts." The Pole swept to a 4-2 lead in the second set, seemingly bound for victory before Li reeled off four games in a row. Favoured at times by luck - she had two cold netcord winners in two pivotal games - Li rode her luck magnificently. Responding superbly under extreme pressure, she turned the contest as Radwanska's physical fragility showed. Radwanska called for a trainer at the end of the set and had her right thigh heavily strapped. Despite her travails, Radwanska snatched a crucial service break in the first game of the deciding set. The unorthodox baseliner edged to within touching distance of victory when she claimed the longest game of the match after 28-minute delay. Germany's Sabine Lisicki serves against Estonia's Kaia Kanepi during their women's singles quarter-final match on day eight of the 2013 Wimbledon Championships tennis tournament. Resuming under centre court's closed roof, Radwanksa pressured Li into a wide forehand and a 4-1 gap. She had match points in the sixth game and six more in the final game.
