Venus Williams will surpass sister Serena for the most main draw matches played at Wimbledon among active players when she takes to the court today.

No.2 seed Simona Halep has won two or more matches in six consecutive tournaments stretching back to Miami in March, a level of consistency unmatched on the WTA Tour in the same timeframe, and will bid to extend that streak to seven today.
No.4 seed Elina Svitolina and No.6 seed Johanna Konta are both looking to make the third round of Wimbledon for the first time today. The Ukrainian lost in the first round in 2013 and 2014 and the second round in 2015 and 2016, while the Briton exited in the first round on her first four appearances, between 2012 and 2015, before making the second round last year.

Beatriz Haddad Maia became the first Brazilian woman to win a match at Wimbledon since Gisele Miro in 1989 when she beat Laura Robson on Monday.

Venus Williams will be getting a sense of déjà vu from her Wimbledon draw. At Roland Garros in May, she beat Wang Qiang in the first round 6-4, 7-6(3) and Elise Mertens in the third round 6-3, 6-1. Here, she felled Mertens in the first round by the tougher scoreline of 7-6(7), 6-4 - and immediately squares off against Wang again.
Victoria Azarenka's comeback from maternity leave continues against No.15 seed Elena Vesnina today. The pair have been competing since 2007, when Azarenka won their first meeting in the semifinals of Tashkent, and the former World No.1 has dominated the head-to-head ever since, winning all seven meetings without ceding a set. Indeed, the only time Vesnina has won more than four games in a set was in the third round of Indian Wells in 2009, when she pushed Azarenka to 6-3, 7-5.
No.8 seed Dominika Cibulkova and her opponent today, Jennifer Brady, both snapped WTA Tour losing streaks with their first-round wins on Monday.

Wang Qiang is seeking to make the third round of a Slam for the first time today - to date, the Chinese No.3 is 0-5 in Slam second round matches, a record she shares among active players with Lara Arruabarrena, Chang Kai-Chen and Aliaksandra Sasnovich. Only Urszula Radwanska, who is 0-9 in Slam second rounds, has made round two more times without taking the next step.

On her debut in 2001, she beat Marissa Irvin 2-6, 6-1, 6-2 before falling to Jennifer Capriati 6-3, 6-1 in the second round; her career-best showing was a 2009 quarterfinal run that featured a win over future champion Marion Bartoli in the third round.
No.11 seed Petra Kvitova lost her first two meetings to Madison Brengle, her opponent today, falling 6-3, 7-6(2) in Stüttgart in 2015 and 0-6, 7-6(1), 6-3 in Dubai in 2016. However, the Czech finally got her revenge in Tokyo last year with a 6-3, 6-3 victory.
