Whilst sister Venus looks a sad shadow of the powerful Grand Slam-winning athlete that devoured many a title, sister Serena could not be living up to her name more impressively. Serene progress since becoming injury-free last year has delivered a string of victories in which, crucially, she has gained a massive psychological advantage over her prime rivals in Victoria Azarenka and Maria Sharapova. Both are outstanding talents but it’s hard to see either displaying sufficient mental resolve to stop the American from taking this week’s French Open title. Azarenka looks the most likely but at present it seems simply a question of how long Williams wants to stay on the tour and continue to rack up evermore titles. It’s hard to take to her at times but never difficult to appreciate the dominating brilliance of her current winning streak.
