WHO: Tiger Woods

WHAT: 57-foot eagle putt

WHERE: 532-yard par-5 7th at Quail Hollow Club

WHEN: Final round of the Wachovia Championship

WHY

Putting is the best part of Woods's game, as he showed on the front nine on Sunday by holing three birdie putts from between eight and 21 feet, plus the monster eagle. At impact his putter is perpendicular to the target line, so his ball rolls end over end with no sidespin. When watching Woods putt, pay attention to the close-up shots that focus on the straight black line on his ball. It never swerves, even on misses.

MARK'S TIP

Line Never Wavers On Perfect Putts

To learn to make square and solid contact, practice with a two-colored ball (right) or draw a thick straight line along the equator of your ball. The ball should roll end over end all the way to the hole, even on putts that break. If you've hit a solid putt with no sidespin, the black line or the line formed where the two colors meet will remain perpendicular to the ground and not swerve a bit.
