SCOTTSDALE, Ariz. — 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. 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 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.


Padraig Harrington and Ryan Moore were tied for third at 16 under.


Gallacher takes 3-shot lead in Dubai

DUBAI, United Arab Emirates — Stephen Gallacher shot a 10-under 62 to grab 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 Scotsman holed a bunker shot on 18 for an eagle to finish with a 21-under total of 195. That improved on Woods’ tournament mark by a shot. Overnight leader Richard Sterne (66) is three strokes behind and Thorbjorn Olesen (67) was five shots back in third place.
