Woods' birdie on 18 forces Open playoff with Mediate

Woods won that three-hole playoff at Valhalla by one shot, and he won the 2005 Masters in a sudden-death playoff with an 8-iron into 15 feet on the first extra hole to beat Chris DiMarco.

This one is a full round on a wounded knee against a 45-year-old with a back so creaky he once contemplated retirement. Now, Mediate feels as though he has nothing to lose.

"I don't know how you make odds on that," Mediate said. "Who knew I would be here playing against him tomorrow?"

Then he noticed Woods standing at the door of the interview room.

"And you better watch yourself tomorrow, pal," Mediate said playfully. "See, he's a little nervous right now."

Woods joined the laughter. Nervous? Probably not. But definitely thrilled to still be playing.
