Grillo has a wonderful swing which produces Dustin Johnson and Jordan Speith-like impact positions without the bowed left wrist at the top of the swing. The secret here is his great pivot movement combined with wonderful use of the right arm and the squaring of the face with the left forearm and wrist. Grillo’s right arm action is not like Hogan’s at all in the backswing as he externally rotates his upper arm and elbow almost immediately in the takeaway and keeps it in front of him during the backswing, but in the forward swing he drives the elbow way in front of his ribcage and gets his hands forward at impact as much as anyone on Tour.
