2017 marks the 20th anniversary of Venus Williams's Wimbledon debut. In 1997, the five-time champion lost in the first round to Poland's Magdalena Grzybowska 4-6, 6-2, 6-4 - but would make the second week 14 times in her subsequent 18 appearances.
Roland Garros champion Jelena Ostapenko faces Belarus's Aliaksandra Sasnovich today. In the past 20 years, seven women have won their first Slam in Paris - and only two have gone on to make the second week at Wimbledon in the same year, Iva Majoli (quarterfinalist in 1997) and Justine Henin (semifinalist in 2003). Anastasia Myskina (2004) and Ana Ivanovic (2008) fell in the third round; Li Na (2011) and Garbiñe Muguruza (2016) lost in the second round; and Francesca Schiavone (2010) exited in the first round.
Andrea Petkovic owns a 4-1 head-to-head lead over No.8 seed Dominika Cibulkova. The Slovak has gone 0-3 in her grass warm-ups - a stark contrast to her 5-0 record heading into Wimbledon this time last year.
Former World No.1 Victoria Azarenka plays her first Slam match since returning from maternity leave against Catherine Bellis today. She is one of four mothers in the main draw - the others are World No.74 Tatjana Maria, World No.80 Evgeniya Rodina and World No.112 Kateryna Bondarenko.
One of Day One's most anticipated first-round matches sees No.4 seed Elina Svitolina square off against Birmingham runner-up - and 2011 Wimbledon girls' champion - Ashleigh Barty. The Ukrainian was the victor in their only previous meeting, 4-6, 6-1, 6-2 in a first-round Fed Cup tie in February.
Johanna Konta faces Hsieh Su-Wei in the first round for the second consecutive Slam. Hsieh bested the British No.1 at Roland Garros in May - as well as in their only previous grass-court meeting in Eastbourne in 2013.
Sabine Lisicki is playing her ninth Wimbledon this year. The German has reached at least the quarterfinals in five of her previous appearances - and in four of those has beaten the reigning Roland Garros champion. The earliest she can meet Jelena Ostapenko this year is in the quarterfinals.
Kristyna Pliskova faces Roberta Vinci for the third time this year today. The Czech has won both their 2017 encounters - 3-6, 7-5, 6-3 in the first round of Dubai and 6-4, 6-4 in the first round of Biel.
Nao Hibino, who faces No.17 seed Madison Keys today, holds the record among active players for most Slam main draws played without a win. The Japanese player is 0-6 in Slam first rounds - just ahead of Belgium's Maryna Zanevska, who is 0-5 at the same stage and who takes on Heather Watson today.
No.18 seed Anastasija Sevastova has lost in the first round of every grass tournament she has played in her career - except Mallorca, where she was runner-up in 2016 and champion this year.
A quartet of under-21 players will be making their Slam debuts at this year's Wimbledon: Anastasia Potapova, Bianca Andreescu, Aryna Sabalenka and Katie Boulter. Get to know their stories here.
