Hantuchova's game is built around natural timing. She is able to
produce "effortless" power from her flowing groundstrokes and possesses
a superb down-the-line forehand and backhand. She possesses a heavy
serve and has a particularly effective "kick" second serve. Her
favourite and most effective construction of a winning point is her
flat serve out wide on the Ad-court, followed by a backhand winner down
the line. Her volleys are very well-produced and often have the deftest
of touch. Due to these attributes she is known as an "All-arounder." A
weakness of Hantuchova since she emerged from the juniors was her lack
of explosive movement around the court. In recent years, however, this
aspect of her tennis has been vastly improved.
She turned professional in 1999 and had her breakthrough year in 2002, when she won her first Tier I tournament and ended the year in the top ten.
Hantuchova has won three WTA singles tournaments in her career, the first in 2002 at the Tier I Pacific Life Open, defeating Martina Hingis 6–3 6–4 in the final, and in 2007 at the same tournament, defeating Svetlana Kuznetsova in the final 6–3 6–4 ending a five-year title drought. Her most recent title came at the Generali Ladies Linz in Austria, where she defeated Patty Schnyder 6–4, 6–2 in the final.
