To mark the anniversary, we got Steve Williams—the man who carried the bag for all four victories—on the Club Lab podcast.

And he had details. Like this one: Tiger used a single wooden tee for the entire 2000 Open Championship at St. Andrews. All four rounds. Every par-3 tee shot. By Sunday, the thing was chipped from every side and barely functional—but it never left the bag.

Williams added a detail that makes it even better: Tiger kept that tee in a Stanford golf pouch for years afterward. Williams would pull it out from time to time to remind him what was possible.

We also discussed what it was like to be inside the ropes, calculating adrenaline into yardages, Nike Tour Accuracy's infancy stage and where Tiger's irons originated. Check it out below.
