The men get the day off on Tuesday, leaving the women to carry the day. Each match features a top four seed, meaning that we could get the top four ranked players in the world in the semifinals, which would be the first time that had happened on the women's side this decade.

CENTRE - SHOW COURT - 1.00 PM START

1. Dinara Safina (RUS) [1] 1 vs Sabine Lisicki (GER) 26
A perplexing battle between an underperformer and an overperformer. It's tough to say who will win, but based on who has been playing closer to their best, it would have to be Lisicki. I think Safina's difficulties on grass will finally catch up with her against the flat hitting, aggressive, courageous German, and she'll be the sole spoiler to the top four party in the semis.
Prediction: Lisicki in three.

2. Victoria Azarenka (BLR) [8] 97 vs Serena Williams (USA) [2] 128
This one could be quite the bloody affair. The two met in the fourth round of the Australian Open earlier this year, with Azarenka winning the first set then retiring midway through the second due to vertigo symptoms. It was a mess. Azarenka was a different type of mess in her fourth round win over Petrova yesterday, throwing a general tantrum the entire time yet still managing to power her way into her first Wimbledon quarterfinal. Serena, for her part, has looked great this entire tournament, but she hasn't faced anyone near Azarenka's caliber. This one could go into overtime.
Prediction: Williams in three.

COURT 1 - SHOW COURT - 1.00 PM START

1. Venus Williams (USA) [3] 33 vs Agnieszka Radwanska (POL) [11] 49
Serena got the opportunity to dismantle Radwanska in last year's Wimbledon quarterfinals, so it's only fair that Venus should get the chance to do so this year. Venus has been hitting the ball very cleanly, and Radwanska has no weapons that Venus won't be able to pound her way through.
Prediction: Williams in two.

2. Francesca Schiavone (ITA) 74 vs Elena Dementieva (RUS) [4] 96
Elena Dementieva's soft draw continues. Two veteran players, neither of whom was talked about much going into this tournament, face off for a spot in the semis, where they will undoubtedly lose meekly to the Serena-Azarenka winner. Dementieva's game is much more stable, and should hold up better to the pressures of the occasion.
Prediction: Dementieva in two.
