LONDON, England - Simona Halep and Agnieszka Radwanska will be our finalists if the seeds hold up - and you're watching highlights from their last meeting above - but there are a whole lot of players who are hoping to break that final up. Read up about all of them - plus all kinds of stats - right here!

1) For the second straight Grand Slam, Serena and Li's early losses have made history.
As the Top 2 seeds at the French Open, Serena Williams and Li Na were both out in the first two rounds - the first time the Top 2 seeds have lost that early at a Grand Slam in the Open Era. And now this is the first time in the Open Era that the Top 2 seeds have lost in the first week of Wimbledon (they both lost third round - Alizé Cornet beat Williams and Barbora Zahlavova Strycova beat Li).

2) Usually at this stage we're down to the last 16, but we're actually down to the last 18.
All 16 third round matches were supposed to be completed on Friday and Saturday, but due to a combination of rain and eventually darkness on Saturday, 14 were completed - the last two matches, between Ana Ivanovic and Sabine Lisicki (with Lisicki leading 6-4, 1-1) and Madison Keys and Yaroslava Shvedova (with Shvedova leading 7-6(7), 6-6) will be completed early on Monday.

3) Ivanovic is trying to become the first player to 40 WTA-level match wins today.
Ana Ivanovic is already the WTA's match win leader with 39 (Carla Suárez Navarro is next with 36) and today she's going for 40. She's actually only ever got to 40 in a season twice before in her career - 2007 (she got to 40 in August and finished at 51) and 2013 (her last win over the year was her 40th).

4) Halep is the highest seed in the second week - again.
At No.3, Simona Halep is the highest seed remaining going into the second week here. It was the same situation at the French Open, where she was the No.4 seed (and the Top 3 seeds all lost first week).

5) Radwanska, the No.4 seed, might be in trouble in the fourth round.
Though this is her best Grand Slam - the only one she has been to the finals of, and the only one she has been to the semifinals or better of more than once - Agnieszka Radwanska has a very tough assignment on Monday, taking on the No.22 seed, Ekaterina Makarova. Not only is Radwanska a surprisingly close-to-even 25-19 against left-handers in her career (.568) compared to an impressive 364-148 against right-handers (.711), but she actually lost her last meeting to Makarova in straight sets, and at this stage of a Grand Slam too (in the fourth round of last year's US Open, 6-4, 6-4).

6) Sharapova has no points to defend the rest of the year.
By winning her second round match here, Maria Sharapova did one better than she did last year - she lost second round here last year and didn't win any matches the rest of the year (read more here).

7) The Czechs are having an historic tournament.
With Petra Kvitova, Lucie Safarova, Barbora Zahlavova Strycova and Tereza Smitkova all through to the fourth round, this is the first time in the Open Era that four women from the Czech Republic are in the second week of a Grand Slam. Zahlavova Strycova and Smitkova are in the second week of a Grand Slam for the first time - for Zahlavova Strycova it's her 33rd Grand Slam, Smitkova her first.

8) Wozniacki is trying to complete her Grand Slam quarterfinal set.
Caroline Wozniacki's shining junior moment came at Wimbledon, so why is this the only one she hasn't reached the quarterfinals of as a pro? Well, the wait might almost be over - read more here.

9) Peng could make some history of her own.
Peng Shuai is in her 36th career Grand Slam and is going for her first quarterfinal - if she does it, only three other women in the Open Era have taken longer to reach their first Grand Slam quarterfinal (Tamarine Tanasugarn 45, Silvia Farina Elia 44, Nathalie Dechy 37 - Judith Wiesner also 36).

10) Who is Smitkova?
Tereza Smitkova might be one of the most unlikeliest players to reach the second week of a Grand Slam in a while. Not only did she come into Wimbledon having only played two WTA main draws before this, falling first round at one and reaching the second round of the other, but she also had to make it through qualifying here and win three main draw matches to get here - she saved two match points against Bojana Jovanovski in the last round too. And at No.175 in the world, if the Czech teen is to make the quarterfinals, she would be the lowest-ranked Wimbledon quarterfinalist in the Open Era.
