Can Serena and Venus Williams make the Wimbledon final an all-Williams affair? We’ll find out on Thursday as each contests the semifinals. 8th-seeded Venus takes on No.4 seed Angelique Kerber, while Serena takes on unseeded World No.50 Elina Vesnina.

We go inside the numbers of today’s semifinals here:

11 -- For the 11th time Venus and Serena have reached the semifinals at the same major. It has happened here at Wimbledon (six times) more than anywhere else. Each time this has happened, either Venus or Serena has taken the title. So, who are you picking?

119 -- Total titles amassed by the Williams sisters, which is 108 more than the other two semifinalists combined. Kerber owns nine titles while Vesnina has two.

27-4 -- Serena Williams lifetime record in Grand Slam semifinals, which is utterly ridiculous when you think about it.

31 years, nine months -- The average age of this year’s four semifinalists, which is the highest average age for a Grand Slam semifinalist field in Open Era history. 2016 also marks the first time that two players aged 34 or older have reached the semifinals at a major.

4 -- Williams sisters finals in Wimbledon history. Serena owns a 3-1 record, with three of four having been concluded in straight sets.

The results:

Serena d. Venus, 2002, 7-6(4), 6-3
Serena d. Venus, 2003, 4-6, 6-4, 6-2
Venus d. Serena, 2008, 7-5, 6-4
Serena d. Venus, 2009, 7-6(3), 6-2

13 -- Elena Vesnina is bidding to become the 13th unseeded player to advance to a Grand Slam final in Open Era history, and the first at Wimbledon.

50 -- Should she advance today, Vesnina would be the lowest-ranked finalist in Wimbledon women’s singles history, with a current ranking of 50.

8-0 -- Venus Williams has never lot a semifinal at Wimbledon, but the 36-year-old American has not been to this stage at SW19 since 2009.

3 -- Venus Williams joins Billie Jean King and Martina Navratilova as one of just three players to have reached a Grand Slam semifinal beyond the age of 36.

4 -- Left-handed players to have reached the Wimbledon final in the Open Era—Ann Jones, Martina Navratilova, Monica Seles, Petra Kvitova. Angelique Kerber is bidding to make it five when she takes on Venus Williams on Day 10.

50 -- Number of aces turned in by the tournament’s current ace leader, Serena Williams. Elena Vesnina is second with 27, Venus Williams has chipped in 14 and Angelique Kerber has 9.

80 -- Percentage of first-serve points won by Serena Williams in her first five matches, which leads all semifinalists. Angelique Kerber is winning 69 percent; Venus Williams is winning 68 percent; Vesnina is winning 67 percent.

10 -- Petra Kvitova and Madison Keys will both drop out of the Top 10 after Wimbledon, with Svetlana Kuznetsova returning to the Top 10 unless Elena Vesnina wins the title. Carla Suarez Navarro will also find herself back inside the Top 10 next week.

1 -- The race for No. 1 continues into the weekend as Angelique Kerber can end Serena Williams’ 177-week run at the top spot by winning the title, provided that Williams loses in the semifinals. No German has been ranked No. 1 since Steffi Graf in March, 30 1997/
