Tuesday

First Round

[1] Serena Williams (USA #1) vs. [Q] Amra Sadikovic (SUI #148)
Head-to-head: First Meeting
Key Stat: Williams is the last women to have won Wimbledon after saving a match point (2009).

Having failed to come away with the title in each of the last three majors, Serena Williams has dusted herself off and is ready to pursue Grand Slam glory at one of her favorite stomping grounds. Her first test will be against Swiss qualifier Amra Sadikovic, a 27-year-old who has only played six tour-level matches in her career. After briefly retiring from tennis, the Swiss has recently returned to the tour with a renewed sense of purpose. Williams, on the other hand, is hoping to log more matches than six this Wimbledon fortnight. The six-time champion owns a 79-10 lifetime record at SW19 and despite the fact that she’s bidding for a historical 22nd major title for the fourth time, the 34-year-old refuses to be bothered by externalities. “Honestly, I don’t feel any pressure,” Williams told assembled press on Sunday during her champion’s press conference. “I feel good and confident.” Williams arrived in London on Monday to give herself plenty of time to get reacquainted with the grass that she has prowled so efficiently since she made her first Wimbledon appearance in 1998. Despite having made the trek 17 times now, Williams says it’s always special. “It’s a unique experience,” she said. “You know, it’s just that one time a year you just get to get on this amazing, beautiful surface. It feels really good.”

Pick: Williams in two

[13] Svetlana Kuznetsova (RUS #14) vs. Caroline Wozniacki (Den #45)
Head-to-head: Wozniacki leads 6-5
Key Stat: A three-time Wimbledon quarterfinalist, Kuznetsova has not reached that far at the All England Club since 2007.

Two longtime rivals will meet for the 12th time and the first at Wimbledon on Tuesday when Caroline Wozniacki and Svetlana Kuznetsova lock horns in a highly enticing first-rounder. They are six years apart in age, and 31 spots separate them in the rankings, but in truth there isn’t a whole lot that divides these two, talent-wise. Wozniacki has slipped in the rankings due to an ankle injury that forced her out for two months this spring, but the Dane has put three events under her belt and is feeling much better about her form after a productive three weeks on the grass. “I feel like I’m getting closer to where I want to be,” she told the WTA Insider Podcast at Eastbourne, where she won two matches before falling in a tight three-setter to Monica Puig. Kuznetsova has had her moments in 2016, most notable her upset of world No.1 Serena Williams in Miami, but the Russian has lost her only match on grass to date in 2016.

Pick: Wozniacki in three

[10] Petra Kvitova (CZE #10) vs. Sorana Cirstea (ROU #85)
Head-to-head: Kvitova leads, 4-2
Key Stat: Two-time champion Petra Kvitova is one of three former Wimbledon champions in the draw.

Typically a grass juggernaut, Petra Kvitova encountered some turbulence on her favorite surface this summer when she was knocked out of Birmingham and Eastbourne in the round of 16. But the 2011 and 2014 champion has more than proven herself at Wimbledon, where she owns a 29-6 lifetime record and has produced some of her most electrifying tennis. That means it will take an exceptional effort from Romania’s Sorana Cirstea to challenge the Czech on Tuesday in a place where Kvitova has always been at her menacing best. In their lone Wimbledon meeting Kvitova eased past Cirstea in straight sets, but the world No.85 does own two victories over Kvitova and has undergone a bit of a revival of late, producing her best tennis since her breakout season in 2013 in the last six months.

Pick: Kvitova in two.

[7] Belinda Bencic (SUI #13) vs. Tsvetana Pironkova (BUL #71)
Head-to-head: Bencic leads, 2-0
Key Stat: Pironkova is playing in her 43rd consecutive major at Wimbledon. It is the third-longest active streak behind Ana Ivanovic (47) and Jelena Jankovic (51).

Belinda Bencic loves playing on grass and excels on the surface; Tsvetana Pironkova loves playing on grass and also excels on the surface. What’s not to love about this highly anticipated first-round matchup between two talented players who win with touch and placement rather than power? Bencic defeated Pironkova in the first round at SW19 last year, and she will come in as the favorite on paper, but the Swiss has yet to find her top physical form after missing two months due to a back injury. After a semifinal in ‘s-Hertogenbosch, Bencic had to pull out of her first match at Birmingham with an injury before being defeated in her first match at Eastbourne by Elena Vesnina. Pironkova has two deep Wimbledon runs under her belt (semifinals in 2010, quarterfinals in 2011) and will surely be hungry to gain revenge on Bencic on Tuesday.

Pick: Pironkova in three

Around the Grounds: Third seed and 2012 runner-up Agnieszka Radwanska will begin her 11th Wimbledon campaign with a first-round battle with Kateryna Kozlova of the Ukraine, who is making her Wimbledon debut. Great Britain’s Johanna Konta defeated Monica Puig in a third-set tiebreaker last year at Nottingham. They’ll meet again in the first round on Tuesday with Konta looking to win for the first time in four tries at Wimbledon.

By the Numbers:

137 – Svetlana Kuznetsova’s win total at the Grand Slam level, which is fourth-most among active players.

31-5 – Caroline Wozniacki’s record in first round matches at majors. The Dane has not dropped a first-rounder since 2012 Wimbledon.
