Re: Serena's 2013 Clay Court Strategy
Serena should just work on not getting so flustered when she sets foot on the grounds of Roland Garros. She's still bothered by the fact that the crowd never really liked her, especially after 2003.
Also, this is my only two cents going into this argument that seems to be brewing:
Ana, Svetlana, and Francesca are all better natural claycourters than Serena, Maria, and Li (who, surprisingly, has not come up in this conversation yet is almost identical in style of play to the other two). However, the final piece of the puzzle on clay is mental toughness and stamina. That's where Serena and Sharapova rise above Svetlana, Francesca, and particularly Ana. Even though Ana has an additional RG final, Berlin title, and RG QF to her name than Sharapova (Serena, btw, has reached the quarters in France in 2001, 2004, 2007, 2009, and 2010. She's not really a bad clay court player), she may not end up being the better clay courter in the end than Maria.
Mental toughness cannot be undervalued on the surface, and Serena and Maria always have the potential to go big in Paris.
