I used to think the golfers hitting the most range balls were doing everything right. Turns out there's a second half to that practice most people never get to — and it's the half that actually shows up on the course.

There's a batting practice study from the nineties, and a quieter follow-up on golfers, that together explain why some grinders never seem to close the gap between the range and a real round. Once you hear the fix, it's a two-minute change to how you already practice.
