TONY JACKLIN TOLD ME HIS GOLF SWING came together in 1969, the year he won the British Open and also won five points in the Ryder Cup that ended in a historic tie, 16 all. A year later Jacklin won the U.S. Open at Hazeltine.
Jacklin played practice rounds with Tom Weiskopf, Bert Yancey and other Americans, and mastered his leg action, a departure from the wristy golf swings of many Brits at that time.
About the above...
"That was a publicity stunt," Jacklin said. "... There was a ship in the Thames with a ... light measuring the distances. They made a performance of bringing the golf balls on the silver tray. ... When you swing and looking at traffic down (there), you get this feeling you're going to go with (the ball). So I was on my back foot the whole time."
