I JUST COMPLETED MY 16TH full season on the PGA Tour. During those 16 years, my scoring average each year has rarely deviated from my career average of 69.90. I pride myself on my consistency, and for the unique way I take care of faults when they pop up in my game. For example, I never look at my swing in photos or on videotape, and my father, Mike, is the only teacher who's ever lent me any real advice or instruction. I know what my swing looks like from my own perspective when I'm standing over the ball. In my opinion, this is the only position from which you can fix faults. And when I do, I always fall back on four key lessons I learned at an early age. I've been performing these fixes tune-ups, really for the better part of three decades. I'm confident they'll help you, too.
