WTA seems like ATP, top 4 + 1 pusher.
Vika, Maria, Serena, Kvitova + Radwanska ==> Nole, Fed, Nadal, Murray + Ferrer
What should Ferrer do to beat top 4?
Ferrer is just a B level baseliner with no special assets. He cant do anything really given his age. Radwanska has the variety, the defense, the consistency, and the court smarts, but she needs to develop a much stronger serve, especialy 2nd serve, and more power off the ground somehow.
