PGA Tour media has been killing it lately with a wide range of YouTube videos focusing on players' pre-round warm-up routines. Not only do the videos provide a behind-the-scenes look at some of the biggest names on Tour, they also serve as a helpful reminder that practice makes perfect, even for the world's best. Jordan Spieth's pre-round warm-up isn't anything out of the ordinary, but very systematic and consistent from one tournament to the next.

In fact, you might say it's downright robotic. But that doesn't mean it isn't effective.

Pay close attention to the percentage of shots under 100 yards he hits in his warm-up.
