Quietly, nearly unnoticed, Paul Casey took a more than handy lead at the AT&T Pebble Beach Pro-Am, finishing his third round at 15 under par.
Casey shot 5-under 67 at Spyglass Hill in Round 3 to move to 15-under for the week.
His closest competitor and four-time victor at this event, Phil Mickelson, moved to 12 under at Pebble Beach after mixing four birdies with four bogeys before taking advantage of the par-five 14th for an eagle to get to two-under for the day.
Mickelson, meanwhile, carded 70 at host course Pebble Beach for a 12-under total, within striking distance of matching Mark O'Meara's record five wins at the event.
Elsewhere on the course, Jordan Spieth's double-bogey at the 18th dropped him from what would have been a tie for seventh place to a tie for 18th at seven under.More news: Christian Hackenberg Forgets He’s Mic’d Up During Game
"It was going to bite me at some point", Spieth said.
Jason Day leads the Australians after his round of 72 today at Pebble Beach saw him lose ground but he is six shots behind the leader and just three shots out of second place so something very special from him tomorrow could yet see him contending for the title.
He was on the original list of commitments without his approval, and said he was never going.
"It's tricky on occasions, but you have to embrace it", Casey said. Casey is playing with Don Colleran, the chief sales officer for FedEx.More news: Iran Marks 40th Anniversary of Revolution
But 54-hole leads have not been friendly to him.
"I am having a blast", said Casey, who has 18 pro victories but only two on the PGA Tour, the last in the 2018 Valspar Championship to end a nine-year drought on the USA circuit.
All three times, Casey shot a final round of 2 over or worse.
The wind was strong enough off the Pacific that he had only a 4-iron into the 14th, and it never left the flag, leaving a tap-in eagle.
"I actually thought it was a successful round", said Mickelson, who said the sometimes-heavy showers made the going tough at times. "I'm looking forward to it".More news: Beijing ‘angered’ as 2 USA warships enter S. China Sea - spokeswoman
