Serena Williams
Coming in a close second on our list is the oldest ladies no.1 in history. Even if the younger Serena is not in the same bracket as Nadal, she is still the queen bee when it comes to behavioral patterns in women’s tennis. The younger Williams has a fixation with bouncing the ball five times on her first serve and only twice on her second ball toss.
Moreover, she uses the same shower preceding her matches and carries her shower sandals to the court. The reigning Wimbledon champion does not feel comfortable in the arena until she has tied her shoelaces in exactly the same way and she also wears the same pair of socks during her winning run in an event.
