Playing style
Krejčíkova is an aggressive player, with an all-court game. She is known for her strong serve, powerful groundstrokes, and wholly complete net game. She has been noted for her ability to play with "contained aggression", and to spontaneously inject pace into rallies without notice. As a result, she is capable of generating and redirecting power both crosscourt and down-the-line with both her groundstrokes, allowing her to hit winners, or induce unforced errors from opponents, with a high degree of accuracy. Her two-handed backhand is arguably her strongest groundstroke, with her being able to generate extreme angles with her backhand, and hit winners from any position on the court. Krejčíkova can strategically apply slice to her backhand, continually breaking up the pace of rallies, allowing her to construct points intelligently. Her forehand is also strong, being applied with heavy topspin, pushing opponents far behind the baseline, and allowing her to dictate rallies. She also frequently deploys the sliced forehand, a rare shot in modern tennis, to surprise opponents and aid point construction. Krejčíkova is an exceptional net player due to her doubles experience, and possesses a complete repertoire of shots to perform at the net. Although Krejčíkova typically plays at the baseline until the opportunity arises to attack the net, she occasionally utilises the
serve-and-volley tactic to surprise opponents, and win points easily. She also possesses a highly effective
drop shot
A drop shot is a shot in some racket sports in which the ball (or birdie) is hit relatively softly, sometimes with topspin or backspin, so that it lands just over and close to the net. A well-placed and well-timed drop shot will make it difficult ...
, which typically lands close to the net, surprising opponents in long baseline rallies; if the opponent manages to retrieve the shot, her strong volleying skills allow her to end the point quickly with an aggressive
volley, or a perfectly weighted
lob., which was instrumental in her defeat of Sakkari in the Roland Garros 2021 semi-final and the winning shot in the 2022 Australian Open doubles final. In the post-match press conference, Krejcikova revealed this was a talent she developed as a junior when the deep lobs would bounce over her shorter opponents’ heads and over the fence!
Despite her aggressive playing style, Krejčíkova possesses excellent movement, speed, stamina, footwork, and court coverage, allowing her to defend to an exceptionally high standard, and she is an effective
counterpuncher, extending rallies until she creates the opportunity to hit a winner. Her first serve is strong, peaking at , allowing her to serve aces and dictate play from the first stroke. She also possesses strong kick and slice second serves, preventing opponents from scoring free points off her second serve.
She is quite prone to aborted ball tosses on serve. On occasion, Krejčíkova does have a tendency to take risks on her second serve, leading to a relatively high double fault count. Due to her aggressive mindset and defensive abilities, Krejčíkova is a dangerous opponent on all surfaces, although her strongest surface is clay, where the high bounce and slow pace allow her to execute her playing style perfectly.
