Tuesday

Quarterfinals

[1] Serena Williams (USA #1) vs. [21] Anastasia Pavlyuchenkova (RUS #23)
Head-to-head: Williams leads, 5-0
Key Stat: Pavlyuchenkova has only won one set against Williams in five previous tilts.

It’s a time-honored tradition at Wimbledon. As the second week kicks in Serena Williams lifts her game to another level. The 21-time major champion did just that on Day 8, easing past Svetlana Kuznetsova, 7-5, 6-0 on Centre Court to move a step closer to a seventh Wimbledon title. On Tuesday she’ll face Russia’s Anastasia Pavlyuchenkova for the sixth time. Is Serena emotionally ready for another battle on Day 9? “I wake up since I was three years old to do this,” Williams told reporters after her victory on Monday. “These are the moments that I live for. The passion and the intensity that I have is what makes me Serena. I can’t change, nor would I ever want to be different.” Though she’s defeated Pavlyuchenkova all five times she’s faced her, Williams is not taking anything for granted heading into her 45^th career Grand Slam quarterfinal. “I just know that going into that match, I definitely need to be ready,” she said. “I’ve lost to players that have never beaten me in the past in some big situations. I definitely don’t want that to happen.”

Pick: Williams in two

Elena Vesnina (RUS #50) vs. [19] Dominika Cibulkova (SVK #18)
Head-to-head: Tied, 3-3
Key Stat: Cibulkova has won nine matches in a row.

The magical ride continued for Dominika Cibulkova at Wimbledon on manic Monday as the Slovakian outlasted Agnieszka Radwanska in a three-set, three-hour thriller that was being tabbed as the best match of the fortnight around the grounds. Cibulkova gave every inch of her being to get past Radwanska and was thankful to get through after saving a match point late in the third set. “Today was the most physically tough, it was the toughest match for me I would say my whole career,” she said. “I felt really, really tired when the match was going on.” On Tuesday she’ll have to dig deep again against surprise quarterfinalist Elena Vesnina if she intends to reach her first career Wimbledon semifinal. Vesnina squeaked by her doubles partner Ekaterina Makarova on Monday, 5-7, 6-1, 9-7, to reach her first Grand Slam quarterfinal in her 42^nd appearance at a major.

Pick: Cibulkova in three

[5] Simona Halep (ROU #5) vs. [4] Angelique Kerber (GER #4)
Head-to-head: Halep leads, 3-1
Key Stat: Kerber is one of three former Grand Slam champions remaining in the draw, along with Venus and Serena Williams.

Two WTA elites backed up their seeds nicely on Day 8, and on Tuesday Simona Halep and Angelique Kerber will vie for a spot in the semifinals at SW19. Halep holds the edge in the pair’s head-to-head but Kerber can claim the confidence that comes with being crowned a Grand Slam champion earlier this year at the Australian Open. “I was feeling that my tennis is getting better and better every day,” said the German after dispatching Misaki Doi in straight sets on Monday. “This is what counts in the second week of a Grand Slam.” Halep, who edged Madison Keys in a tough round of 16 tussle on Monday, is ready for another big challenge in the quarterfinals. “I know Angelique very well,” Halep said. “I’m confident. I have to be. I am playing well. I am into the tournament already, so I had tough matches before. I’m looking forward to play against her, and I know it’s going to be tough.” Expect this battle of former Wimbledon semifinalists to be epic. Both players are dialing in their best form, and both are hungry to advance.

Pick: Halep in three

[8] Venus Williams (USA #8) vs. Yaroslava Shvedova (KAZ #96)
Head-to-head: First meeting
Key Stat: Williams has reached the Wimbledon quarterfinals for the first time in six years.

A Wimbledon legend, finding her mojo at the scene of her first Grand Slam triumph. That’s the story of 36-year-old Venus Williams, the oldest woman remaining in the draw but also a very legitimate threat to recapture the glory of Wimbledons past here at SW19. Williams was in stellar form on Monday, taking out Carla Suárez Navarro in straight sets to set up a quarterfinal clash with unseeded world No.96 Yaroslava Shvedova. Despite the fact that Williams hasn’t pushed this deep in a Wimbledon draw since 2010, the five-time champion is confident that she’s ready to keep this run going. “Yeah, it’s been a few years,” Williams said. “But I’ve been here before. I’m not, like, a deer in the headlights. So, of course, I want more. That’s what anybody would want in a quarterfinal.”

Pick: Williams in three
