Phil Mickelson shot a four-under par 68 to reach 10-under and give himself a chance on Sunday.
Brendan Steele erased a two-shot deficit in the final round and completed a successful defense of his Safeway Open championship on Sunday in Napa, Calif. Mickelson is a 42-time PGA Tour champion, a World Golf Hall of Fame member, and the victor of five majors.
Zac Blair (66) and Tony Finau (65) were 9 under, and Graham DeLaet (67) and Brian Davis (66) were another stroke back.
"I didn't hit it the best".
The American had a favourable bounce on the approach to the par-five fifth and holed the subsequent putt to eagle the hole in a round which included six birdies, and is now clear 7/1 favourite with Sky Bet.
Defending champion Brendan Steele is a shot further back and eased to 11/2 from 11/4 overnight. "I made 17 greens out there, left myself in some good spots, made a few of them and it was just kind of easy out there".
"A little bit of everything worked for me today", Steele told reporters.
"This place is so great for me", said Steele. It's his third career victory on the PGA Tour.
The 2017-18 PGA Tour season-opening event proved be quite fruitful for the 47-year-old as he finally delivered on the course when it mattered.
"I played really well the whole day", Hoge told the Napa Valley Register. A bogey-free 7-under 65 put Hatton, a second-round co-leader, at 18-under 198 and in a commanding position to defend the title he won by four shots a year ago.
The current leader Tyler Duncan was tied at the top after the first round but bogeyed on the second, third and fourth to sit at one under for the day after four second-round holes on the front nine.
"After mixing three bogeys with two birdies on the front nine, Duncan picked up shots at 11, 14 and 16 â€" while dropping one at 15.
Finau's round consisted of an eagle-3 on No. 5, birdies on Nos.
Five-time major champion Phil Mickelson also remains in the hunt to claim his first title since the 2013 Open Championship as he is just four shots behind Duncan after his third-round 68. Daly had missed the cuts in his past 12 PGA Tour events.
