Russia to round out the ladies' semifinals.
Elena Dementieva (RUS) v. Serena Williams (USA)
Dementieva is very aggressive with her groundstrokes and has shown measured service improvements. She rarely suffers a loss to a player ranked below her and also reached the semifinals last year in London.
But her serve remains attackable and a solid volley still is missing from her game.
Williams' all-court game and immediate aggressiveness from the baseline and serve should keep Dementieva on the defense.
Dementieva lost to Williams 6-3, 6-4 in their last meeting at the Australian Open semifinals in January on a hardcourt and could lose today by a more one-sided score. A grass surface suits Williams' game much more than her Russian counterpart's.
Winner: Serena Williams
Dinara Safina (RUS) v. Venus Williams (USA)
Venus Williams leads Dinara Safina head to head 2-1 but lost their last meeting in the spring in the Rome semifinals 6-7(3-7), 6-3, 6-4 on clay.
On a grasscourt however, Williams has much more experience winning than Safina. Williams is a five time Wimbledon champion while Safina finds herself still searching for her first grand slam title.
Safina lost the opening set in her last two matches, but managed to turn the matches around for victories. Williams has won 19 matches in a row at Wimbledon and another slow start for Safina could be deadly.
The first ball of each rally early in the match will be key as Williams' serve is an overwhelming weapon on grasscourts. Safina will need to attack Williams before she is attacked.
Safina is a powerful player from the baseline who likes to hit hard. But Williams likes and thrives on pace. The American is also the better mover and has a better volley and serve, all of which are key on grass.
Winner: Venus Williams
