Tiger Woods didn't take the lead until the 10th hole and had to make a 7-foot birdie on the 18th to get past Robert Allenby on Thursday in the second round of the Match Play Championship in Carlsbad, Calif.
No. 2 seed Vijay Singh overcame a slow start to beat Miguel Angel Jimenez, the first time in seven tries that Singh advanced to the third round. Third-seeded Retief Goosen also won, but not before Ben Crane made a hole-in-one on the 16th hole to make him sweat.
Phil Mickelson missed several 5-foot putts, but he holed a 25-foot eagle putt on the 11th that sent him on his way to a victory over John Daly.
The best rally came from Padraig Harrington, who birdied the last three holes to send his match into overtime, then beat Angel Cabrera with a par on the first extra hole.
After two days of wild swings in emotion and momentum, only 16 players remained. Six of the top eight seeds are still around, the highest number since the Accenture Match Play Championship began in 1999.
A day after Woods finished off Stephen Ames in the minimum 10 holes, it took the No. 1 seed that long simply to get his first lead.
Mark Wilson shot an opening-round 64 to take the lead at the Chrysler Classic of Tucson, two shots ahead of Doug Barron, Gabriel Hjertstedt, Jerry Kelly, John Riegger and Duffy Waldorf.
Wilson's 8-under was anchored by a 30 on the front nine. He started the tournament on the 10th tee, made the turn at 2-under and got rolling with an eagle on No. 2, a tricky par-5 with a narrow fairway and an undulating green.
Wilson drained a 28-foot putt and then logged birdies on the third, fourth, seventh and ninth holes at par-72 Tucson National. A bogey at No. 18 was the only blemish on what he called one of the best rounds of his career.
The Chrysler Classic has had a first-time champion 14 times, including five of the last six years. Wilson would be a candidate to extend the streak.
