Offensive / Medium
Winning only 36% of her points by the errors of her rivals (below average), Serena Williams is not a Retriever. Her game style is to serve big, to be aggressive from the baseline and she doesn't count on her opponents' errors to win a match.
Retriever - Low
From the back of the court, Serena Williams is a Tempo player. Playing close to her baseline, she generates pace on every ball. Her aggressive return is also the trademark of the Tempo players.
Tempo / High
Even though Serena Williams is more a Tempo player than a Puncher, she can still accelerate slower balls with her forehand. However, Punchers run around their backhand much more than her and they also play with more topspin.
