David Ferrer, Petra Kvitova cruise into Wimbledon quarter-finals after straightforward wins on Monday David Ferrer returns against Croatia's Ivan Dodig during their fourth round match. DAVID Ferrer and Petra Kvitova cruised into the quarter-finals at Wimbledon after reasonably straightforward wins in their respective draws on Monday. Ferrer will claim a career-high ranking of world No.3, usurping Roger Federer, after grinding past Croat Ivan Dodig 6-7 (3-7) 7-6 (8-6) 6-1 6-1. Currently ranked No.4 behind Novak Djokovic, Andy Murray and Federer, the Spaniard is guaranteed of overtaking Federer after the seven-time champion lost in the second round to Sergiy Stakhovsky. Ferrer was followed into the last eight by Polish 24th seed Jerzy Janowicz, who survived Austria's Jurgen Melzer 3-6 7-6 (7-1) 6-4 4-6 6-3. Janowicz's compatriot Lukasz Kubot completed a glorious day for Polish tennis by overcoming France's Adrian Mannarino 4-6 6-3 3-6 6-3 6-4. The pair will clash tomorrow (Wednesday) for a semi-final berth. In the women's draw, Kvitova has extended an excellent Wimbledon record, forging into the All England Club's quarter-finals with straight-sets success over Spaniard Carla Suarez Navarro. The Czech left-hander was the first player - male or female - to reach the last eight with a controlled 7-6 (7-5) 6-3 victory in 84 minutes. Petra Kvitova on her way to becoming the first singles player into the quarter-finals. Seeded eighth, Kvitova showed no sign of the inconsistency that has seen the left-hander slide from world No 2. Kvitova has made at least the quarters here since reaching the 2010 semi-finals, winning the title in two years ago and losing in the quarters to eventual champion Serena Williams last season. Often prone to confidence and concentration lapses, Kvitova was at her attacking best against defensive Suarez Navarro. She produced 23 winners and 21 unforced errors, but did not drop serve. Kvitova will play Kirsten Flipkens tonight for a place in the semi-finals. The Belgian 20th seed overcame Italian Flavia Pennetta 7-6 (7-2) 6-3. Flipkens, 27, had never previously reached the quarters of a major. Meanwhile in the boys championship, rising Australian star Nick Kyrgios has made a strong start. Ranked No.1 in the world, the Australian Open junior champion banished British wild card Evan Hoyt 6-4 6-3 to reach the second round. Surprisingly not offered a wildcard into the men's singles qualifying or main draw, Kyrgios is seeded meet compatriot Thanasi Kokkinakis in the semi-finals. Kyrgios rocked Czech veteran Radek Stepanek with first-round victory at the French Open before disappointing in the Roland Garros juniors with a second-round exit. Recovered from stress fractures in his back, Kokkinakis entered Wimbledon as a wildcard.
