Playing style

Cibulková swinging a forehand.

In 2014, Steve Tignor of Tennis.com labeled Cibulková "a threat to everyone".^[24]

Self-described as a player with "a lot of energy",^[5] Cibulková employs an aggressive style that is largely founded on speed and power.^[25] She is recognized for her exceptional racquet-head speed,^[24] which enables her to produce deep groundstrokes with her forehand and powerful shots with her backhand. She is also known for approaching the net and finishing points with swing volleys.^[24][26] Her aggressive shots have been noted for their ability to force errors or produce winners during extended rallies.^[27]

On defense, she often attacks second serves with quick forehands, and hits prompt returns while taking the ball on the rise. Occasionally, she will break a prolonged rally by mixing in a drop shot. Her lower body strength creates quickness around the court, enabling her to reach and return shots.^[24][25]
