Phil Mickelson drew the loudest roars from the biggest crowd in golf history Saturday at the Phoenix Open.
Mickelson nearly aced the par-3 16th, hitting a 9-iron to a foot to set up a birdie on the rowdy stadium hole packed with nearly 20,000 screaming fans.
Estimated at 179,022, the third-round crowd broke the record of 173,210 set last year, also on a Saturday at fan-friendly TPC Scottsdale.
The event has drawn 467,030 for the week and is in position to break the mark of 538,356 set in 2008.
Mickelson birdied the final four holes and five of the last six for a 7-under-par 64 and a six-stroke lead over Brandt Snedeker.
The 42-year-old former Arizona State star has led after each round, opening with a 60 and shooting a 65 on Friday. He fell a stroke short of the tour record for the first 54 holes, and matched the tournament mark set by Mark Calcavecchia in 2001.
Making his 24th appearance in the event that he won in 1996 and 2005, Mickelson is trying to complete his third career wire-to-wire victory and first since the 2006 BellSouth Classic — a 13-stroke blowout the week before the second of his three Masters victories.
He also is in position to match the tournament record of three victories set by Arnold Palmer and matched by Gene Littler and Calcavecchia. Mickelson won the last of his 40 PGA Tour titles 51 weeks ago at Pebble Beach.
Snedeker had a 65 to reach 18 under.
Padraig Harrington and Ryan Moore were tied for third at 16 under. Harrington, making his first appearance in the event, shot a 63, and Moore had a 65.
Harrington is winless on the PGA Tour since sweeping the British Open and PGA Championship in 2008, and hasn't won anywhere since the Asian Tour's 2010 Johor Open.
PGA EUROPEAN: Stephen Gallacher shot a 10-under 62 to take a three-shot lead at the Dubai Desert Classic and break a three-round scoring record set by Tiger Woods 12 years ago.
The 111th-ranked Gallacher is looking for his first European Tour win since 2004. He holed a 25-yard bunker shot on the 18th for an eagle to finish with a 21-under 195 in rare rainy conditions in the desert. That improved on Woods' tournament mark by a shot and just missed tying the course record of 61 set in 1994 by Ernie Els.
