Trevino's secret

is my secret too. The left hand holding firmly on the club controls where the face is looking, and that factor -- where it's looking, more than path, more than center hit -- controls the direction that the ball starts.

The old-timers (i.e. the golfers who were old when I was young) used to talk about "don't lose the club at the top." I figured out early that the only way I could be sure of where the face was pointed was to be aware of where my left hand, really the knuckles and/or back of the hand, was throughout the stroke.

The release is an un-hinging motion, a backhand left-handed slap at the ball, supported by a continuing rotation through the ball. The hand gives direction, the rotating core provides power.
