"I guess to make one on the last - that was a long, tough hard hole that's usually a driver, 8-or 9-iron, and I had to whistle a 4-iron in after a good drive".
"I'm enjoying it and can't wait for tomorrow". He also made a tough save on the par-3 17th and shot a 2-under 70, giving him a good chance to match Mark O'Meara's record of five AT&T Pebble Beach titles.
He said: "The three blasts means it's bad conditions, but you can finish the hole and I'm like, 'We can finish the hole?' I've never been so happy". "The bit you can't control, the weather, you've just got to cross your fingers and hope you're at the right part of the golf course at the right time".
He was in the clubhouse on 10 under, alongside fellow Americans Lucas Glover (66), Scott Langley (69) and England's Paul Casey (64). Mickelson had consecutive bogeys as the wind and rain were at its worst along the coastal holes of Nos. "That thing was way out there", he said with pride of the 330-yard poke.
Jordan Spieth, who won at Pebble two years ago, had the lead at one stage in round three but made two double bogeys on the back nine at Pebble and is tied for 18th after a 74, third-ranked Dustin Johnson, a two-time champion in the tournament, is tied for 47th after a 73 at Pebble, and defending champion Ted Potter Jr. shot 71 at Monterey Peninsula and missed the 54-hole cut by a whopping 10 shots. They have a four-shot lead in the pro-am.
Mickelson takes some confidence from his history at Pebble but knows that alone will not carry him to victory.
Leader Casey, meanwhile, said there was room for improvement in his own game. "That's been the real key to my play the first three days".
