Scattered Seeds - The Ladies" Wimbledon Championship Updated
For the first time ever in a grand slam event, the top four seeds failed to reach the quarter finals.
I stated in my tournament preview that the event is wide open, and so it has proved.
However, as unexpected as it is to see the world number 133 (Jie Zheng) reach the semi finals, there is still an air of familiarity about the ladies' championship.
The Williams sisters have moved comfortably through the draw and look likely to add to the nine Wimbledon final appearances they have achieved between them this century.
Few would bet against a repeat of their showdowns in 2002 and 2003, both of which Serena won.
I tipped the younger sister for glory at odds of 5.
2 (4/1) with Betfair at the start of tournament and I stand by that prediction.
She was in devastating form in her straight sets quarter final win over Agnieszka Radwanska and I have never seen her so focused and driven to win.
Her sister will struggle to deal with a serve that has seemed unreturnable at times.
The familiar success of the Williams sisters at Wimbledon must be a frustrating phenomenon for the game's elite players.
They have recovered from what seemed terminal slides down the rankings in 2006 but remain enigmatic figures who reserve their best performances for the grass courts of Wimbledon.
Venus has not won another grand slam since 2001.
They perform sporadically on the tour and have suffered accusations of being part-time players, interested more by the fashion world and other interests.
However, any lack of preparation for Wimbledon does not disguise their skill on their favourite surface and we should not see the sisters' success at SW19 as a reflection of mediocrity in the elite players.
Similarly, the pool of talent is bigger than it ever has been, making upsets in the grand slams more likely.
There is a group of emerging Russian and eastern European players, including Radwanska, Agnes Szavay, Dinara Safina and Anna Chakvetadze, who are already in the top 15 of the rankings and are poised to make big impacts at the major events.
There had never been a female Russian grand slam winner before 2004 but there has been three since that breakthrough year (Anastasia Myskina, Svetlana Kuznetsova and Maria Sharapova).
There might soon be a new name to add to that list, as Wimbledon fifth seed Elena Dementieva continues to reach the business end of slams and there are a clutch of young Russian players breaking into the top 100.
