Woody Austin easily handled Boo Weekley, 3 and 2, to advance to play defending champion Henrik Stenson, who hung on to beat Jonathan Byrd. Stenson won his ninth straight match, the third-longest streak in the Match Play Championship.
Stewart Cink took advantage of sloppy play by Colin Montgomerie to deny the Scot valuable world ranking points, winning 4 and 2. Cink will play U.S. Open champion Angel Cabrera, who made six birdies on the front nine and beat Steve Stricker, 4 and 3.
Justin Leonard dispatched Stuart Appleby, 3 and 2, running off five straight birdies at the turn. He plays Vijay Singh, who rallied from 2 down with two holes to play and beat Rod Pampling on the 25th hole.
Cabrera and Leonard are the only players to have not played the 18th hole at Dove Mountain.
Byrd had not played the 15th hole until Friday, and he birdied it to square his match with Stenson. The big Swede took advantage of his power to win the 17th, then hung on for the victory.
No match was more compelling than Woods and Baddeley.
The Aussie, who first played a practice round with Woods as an 18-year-old amateur, took his first lead with a 12-foot birdie on the 14th, after Woods missed from 15 feet. From there, Baddeley played away from the dangerous slopes to the center of the green, making Woods beat him.
"He did all the things you were supposed to do when you have the lead," Woods said.
And Woods did what he usually does, starting with an 8-iron into 2 feet for birdie on the 16th to tie the match. And on they went, both reaching the par-5 17th in two for a putt at eagle, both finding the 18th fairway for a decent look at birdie on the 18th.
Woods could only think of one other match he played at such a high level, when he went the 36-hole distance with Mark O'Meara in the final of the World Match Play Championship in England in 1998.
He lost that match. This time, he gets to keep playing.
