Jelena Jankovic is often regarded as one of the fittest and toughest players in recent years of women's tennis for her great defensive abilities and footwork, which classifies her as a counterpuncher. Jelena is known for being one of the few players who can slide on all surfaces, further enhancing her defense. In 2007, she played more matches than any other player and maintained her third rank as well, which is the proof of her incredible stamina and well-balanced performance. Jankovic has very consistent ground strokes and likes to go down the line more often than crosscourt. Her signature shot is her two-handed backhand down the line; she hits it with excellent pace and can drive it deep for an outright winner and also the fact that she can hit her backhand any angle from her court position. She also has a solid forehand and a decent net game, being able to hit effective drive, drop and swinging volleys. Her main weakness is the fact her serve is very attackable. She likes to spin it in on the first and second serve which can lead to her getting broken many times in matches against good baseline players. However it had improved recently, Jelena served a 120 mph serve at the 2009 US Open
