Collin Morikawa Wins The 2020 PGA Championship
At age 23 Collin Morikawa has won his first major championship after a final round 64.
So what can we learn from his swing?
He has a bowed left wrist at the top of his swing allowing him to shallow the club in transition.
At impact his right arm is still bent and on the shaft plane.
Post impact his right arm is fully extended
Did you notice how far off the ground he gets his right heel coming into the ball, Like Justin Thomas does? This allows him to work his left side up through impact whilst still allowing the right side to work down.
Why do they do this? Because it changes the centrifugal force into centripetal force increasing the club head's speed significantly.
