Scott Brown stole the limelight from more illustrious names to take a share of the lead after the first round of the Farmers Insurance Open in San Diego.
Brown produced a brilliant finish to his round, reeling off eight birdies in the final 11 holes to finish six under par along with Andrew Loupe.
"I knew I was hitting it good," the 32-year-old told the Golf Channel, who quizzed him about his sluggish start.
"I was hitting good shots, I just made a couple of stupid bogeys. I hit a ball in the hazard and made bogey on a par-five but I really hit some close iron shots and fortunately made some putts.
“And it turned into me birdieing eight of my last 11 (holes,) so that was nice."
Loupe, who was tackling the easier North course, had two eagles and a trio of birdies in his round as he chases his first ever PGA Tour win.
Billy Horschel, Patton Kizzire, Harold Varner III, Rob Oppenheim, and Tom Hoge form a group just one shot back from Brown and Loupe, while Phil Mickleson recovered from a double bogey at the second to finish three strokes off the lead.
There was significantly less joy for Jason Day, though, who still appeared to be suffering the effects of the flu that saw him miss the pro-am, as he fired a disappointing on-par 72.
Rickie Fowler fared even worse, finishing the round one over par and branding his performance as “terrible”.
