In tennis, a player may be able to reach balls on the backhand side more easily if they're able to use the weaker hand. An example of a player who is ambidextrous is Luke Jensen. Due to a physical advantage on the space of time needed when matching the ball with the racket simultaneously with tagging the opponent's movement, being laterality-crossed on eyedness with handedness may be a decisive factor for outstanding performance, since the hand which strikes the ball can do it while the overriding eye, matching with this hand, can be tagging the opponent's movement-decisions. Such have the case of Rafael Nadal who uses his right hand for writing, but plays tennis with left. There are many players who are naturally right handed but play lefty and vice versa. Evgenia Kulikovskaya is also an ambidextrous player, Kulikovskaya played with two forehands and no backhand, switching her racket hand depending on where the ball was coming. Jan-Michael Gambill is the opposite case of Kulikovskaya, since he played with a two handed forehand and backhand, although he served with his right hand. Other famous examples of a two handed forehand are Fabrice Santoro and Monica Seles. Seles' playing style was unusual in that she hit with two hands on both sides and, at the same time, always kept her (dominant) left hand at the base of her racket. This meant that she hit her forehand cross-handed. Currently, Maria Sharapova is also known to be ambidextrous. Cheong-eui Kim is a truly ambidextrous player with no backhand, and can serve left-handed as well as right-handed.
