"I played for a 167-yard shot and tried to hit just a comfortable or stock 9-iron, and the ball ended up flying that far and released to the hole. Having played this course and that hole over the years and knowing what your body does and how to adjust to it has helped me, and certainly it did today."
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 fans 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.
"I know how good Snedeker is and how hot he can get with a putter," Mickelson said. "He can make birdie from just about anywhere. He's going to make a run tomorrow. I, hopefully, will be able to keep pace."
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 wire-to-wire victory and first since the 2006 BellSouth Classic .
"To me, the wire-to-wire isn't that important except for now I'm three rounds and the fourth one is kind of the more important one," Mickelson said.
He's 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.
