The greatest golfer in history may have had a direct impact on whether Rafael Nadal becomes the greatest tennis player in history.
A tennis tip Jack Nicklaus gave in a video helped shape Nadal's new serve, according to the world No. 1's uncle and coach, Toni Nadal.
The ATP website reports:
"I saw a video by Jack Nicklaus that changed my vision," Toni Nadal, Rafa's uncle and coach, told daily newspaper ABC. "In it Nicklaus said: 'First strike far, then we will think about getting the ball inside.' I said to myself: 'This man must be right'. That is what I applied with Rafael. First strike hard, then we will get the ball inside," he added.
Nadal's increased the speed of his serve at the Open and was able to put away service games with ease. He was only broken five times during the tournament.
Nicklaus, who won 18 golf majors, is an avid tennis player. He has three grass courts on his property and tries to play every weekend.
