91 holes. One injured leg. One unforgettable win.

On the last green of regulation, Tiger Woods had one way to keep the U.S. Open alive: make birdie. Rocco Mediate was already in at one under par. Woods, playing through a serious left-leg injury, had a putt that would determine whether his week ended on Sunday or stretched into one more day.

He made it. That putt forced an 18-hole playoff. What followed became a second, separate drama: the game’s biggest star against an unlikely challenger who refused to go away.

The injury he carried in

Woods had undergone surgery on his left knee in April. He arrived at Torrey Pines without a fully repaired anterior cruciate ligament and with stress fractures in his left tibia. The extent of the injuries became public after the championship. During the rounds, viewers could see him wince after swings, but the full explanation was still to come.

There was a reason this particular course offered hope. Woods knew Torrey Pines exceptionally well and had won the PGA Tour event held there repeatedly. Familiarity, though, could not make the South Course or five days of competitive golf painless. Every shot asked him to rotate through the injured leg. Every round made the possibility of simply finishing more remarkable.

The challenger across the fairway

Mediate made the contest more than a story about endurance. At 45, he was chasing a first major championship against the world’s most formidable closer. He played with the ease and nerve that made spectators root for him, and he kept giving Woods another problem to solve. His place in the story is not as a spectator to Tiger’s pain; he was the opponent who pushed the champion to the limit.

After 72 holes, both men stood at one under par. Under the U.S. Open’s format at the time, that meant a full 18-hole playoff on Monday. A dramatic Sunday finish was suddenly only the halfway point of the ending.

Sunday’s putt was only the beginning

To get to Monday, Woods had to birdie the par-5 18th on Sunday. His putt fell, the crowd erupted, and Mediate’s wait for a champion became a wait for another round. The two players returned the next morning with everything reset to zero.

Woods built a lead in the playoff, but Mediate came back. Through 17 holes, Mediate led by one. Once again Woods reached the 18th needing birdie to avoid defeat. Once again he found one. Both players signed for even-par 71s in the playoff, which sent them to sudden death.

The 91st hole

They went to the par-4 seventh. Mediate’s drive found a fairway bunker, and the trouble that followed left him with a long par putt. Woods found the fairway and green. His birdie attempt stopped near the hole; a par was enough when Mediate could not save his own. After four regulation rounds, an 18-hole playoff and one more hole, Tiger Woods had his third U.S. Open and 14th major.

He underwent further knee surgery after the win and missed the rest of the 2008 season. That aftermath changes the way the championship reads in hindsight. This was not simply a champion surviving one painful shot, or a heroic Sunday putt viewed in isolation. It was a sustained performance against both a relentless opponent and a physical limit that eventually required him to stop playing.

The image most people remember is Woods celebrating on the 72nd green. The victory actually required another 19 holes. Mediate made sure that a defining moment became a defining week.
