Stephens is an all-court player. She hits her forehand with a large swing and as a result the shot can be either a strength or a weakness for her. Stephens sports a powerful two-handed backhand. Cross-court, she tends to hit a very steady ball, often hoping to run around her backhand in order to hit an aggressive forehand. She often finishes points at the net and is a competent volleyer. In her 2013 Australian Open match against Serena Williams, she won 18 of 20 (90%) net points. She also has a good serve with a very fluid motion.
Stephens often stays well behind the baseline, relying on her athleticism to chase and return balls. She is capable of defending against powerfully-hit shots, and occasionally turns defensive shots into offensive shots. Fitness is one of her biggest strengths on the tennis court.
Only WTA Tour main draw (incl. Grand Slams), Olympics and Fed Cup results are considered.
