Images from a swing sequence breakdown for Jason Day.
Jason’s lines are very good - his feet, hips, forearms, shoulders and eyes are all parallel to his target line. Both legs are pushing into the ground, creating a very stable base. (Analysis: GCA lead coach Mitchell Spearman; photo: Fred Vuich)
Note how Jason’s right thumb points down the shaft at the clubhead, an indication that there’s no independent movement of his hands on the takeaway. (Analysis: GCA lead coach Mitchell Spearman; photo: Fred Vuich)
You start to see some rotation of the forearms here. Note the shadow on the ground cast by the club shaft, and how it’s perfectly parallel to his toe line and target line. (Analysis: GCA lead coach Mitchell Spearman; photo: Fred Vuich)
You can clearly see the continued resistance from Jason’s lower body as his arms swing up, which is one reason why he’s able to generate so much torque and power. (Analysis: GCA lead coach Mitchell Spearman; photo: Fred Vuich)
FAVORITE MOVE No. 1: If you look closely enough, you’ll see some flex in the shaft at the top of his backswing, a sign of the tremendous amount of power he’s stored and is about to unleash. (Analysis: GCA lead coach Mitchell Spearman; photo: Fred Vuich)
Want to know how Jason hits the ball so high? It starts here. Note how much more tilted his hat is from the previous frame, and how the right ear is moving down toward the ground. (Analysis: GCA lead coach Mitchell Spearman; photo: Fred Vuich)
You can literally draw a straight line from the bill of his cap to the ball, an indication that he’s swinging down from the inside and is much more tilted behind the ball with his spine. He’s in perfect position to hit up on the ball. (Analysis: GCA lead coach Mitchell Spearman; photo: Fred Vuich)
FAVORITE MOVE No. 2: What I like here is how Jason’s upper body looks smaller than it was at address. It’s as if he’s doing a crunch - his belly (belt) is coming up while his head stays down. (Analysis: GCA lead coach Mitchell Spearman; photo: Fred Vuich)
FAVORITE MOVE No. 3: Look at the pitch of Jason’s eyes! The angle your eyes swing on is very much the same angle your shoulders swing on. So if you want to launch it high, look high above the level of the clouds. (Analysis: GCA lead coach Mitchell Spearman; photo: Fred Vuich)
Jason’s right elbow has rotated all the way through the shot and his hands are nearly in the same position that they were at the top of the backswing. That’s power! (Analysis: GCA lead coach Mitchell Spearman; photo: Fred Vuich)
