Great, will she keep it until Wimbledon?
Yes, I think so. Top 4 players will remain the same until Wimbledon. Serena, Vika and Maria shouldn't play any tournaments before it, but most of top 10 and top 20 players from Aga Radwanska to Sloane Stephens should play in Eastbourne (WTA premier where winner gets 470 points). In Wimbledon Serena tries to defend her 2000 points as last year's champion, Aga as a finalist has 1400 points, Vika as a semifinalist has 900 points and Maria Sharapova has only 280 points (R16) to defend.
