LONDON, England - How many minutes has Venus Williams spent on court? What does Angelique Kerber need to do to top the rankings? And just how impressive has Serena Williams' serving been?

These are just a few of the questions answered in a Wimbledon semifinal edition of wtatennis.com's By The Numbers.

618 - Venus Williams has taken 618 minutes to win her five matches - 243 minutes more than her semifinal opponent, Angelique Kerber. Serena Williams and Elena Vesnina have spent 423 and 552 minutes, respectively, on court thus far.

122 - This February, Vesnina was ranked No.122. Her run to the semifinals guarantees that she will be in the Top 25 next Monday. By reaching the final she would rise to a career-high No.18.

80 - Serena's peerless delivery has helped her win 161 of 202 (80%) points on her first serve - the best percentage of any singles player this fortnight.

66 - Venus has won 66 of her 79 meetings with left-handers on tour. Three of these defeats have come against Kerber, including their solitary meeting on grass at the 2012 Olympics.

50 - Serena has struck more aces, 50, than any other player en route to the last four. Kerber, meanwhile, has hit just nine.

42 - In her 41 previous Grand Slam appearances Vesnina had never been beyond the fourth round. Only three others players have played 42 or more majors before reaching a semifinal: Nathalie Tauziat (42), Roberta Vinci (44) and Elena Likhovtseva (46).

36 - At 36 years old, Venus is the oldest player to reach the last four at a major since Martina Navratilova, then 37, at Wimbledon in 1994.

31 - The average age of Venus (36), Serena (34), Vesnina (29) and Kerber (28) is 31 years and nine months - the highest at the semifinals for any major in Open Era history.

20 - Victory over Cibulkova took Vesnina's 2016 match win tally to 35. Last season, she notched up just 15 all season.

11 - Number of times Serena and Venus have now reached the semifinal stage at the same major. Ominously for Kerber and Vesnina, on each of the previous 10 occasions one of the sisters has gone on to lift the title. 

8 - Venus has won all eight of her previous Wimbledon semifinals.

5 - Vesnina is the fifth unseeded player to make the Wimbledon semifinals since the number of seeds was increased to 32 in 2001; the others were Zheng Jie (2008), Petra Kvitova (2010), Tsvetana Pironkova (2010) and Sabine Lisicki (2011).

2 - By virtue of her run to the semifinals Kerber will return to No.2 in the rankings, at the expense of Garbiñe Muguruza. Should the German lift the title and Serena fails to make the final then she would rise to No.1 for the first time in her career.

1 - This is the first time in Open Era history that two players aged 34 or older have reached the last four at the same major.

0 - The number of sets Kerber has dropped en route to the semifinals. The last player to win a major without dropping a set was Serena at the 2014 US Open. Marion Bartoli was the last to achieve the feat at Wimbledon, in 2013.
