Mickelson needed to birdie the closing two holes on the 60th anniversary of the event at the La Quinta Country Club to join another of golf’s elite clubs but could only manage to birdie the 18th and in the process he also became the first player on the PGA Tour to shoot 60 three times.
Mickelson’s 60 comes also on the 20th anniversary that David Duval posted a final round 59 to win the 1999 Bob Hope Chrysler Classic also at La Quinta.
And while Mickelson was one shot shy of matching Dubal’s feat he will take a three shot lead over fellow American Adam Long into day two of the $US 5.9m event.
“I haven’t really had the intense practice sessions that I would like, but I felt like all parts were okay and it just clicked, … and the bad shots that I hit I got away with.
“It was a fun day, but I certainly did not expect this to be the case, but I’m also excited to start the year so I was fresh.”
Mickelson tweeted: “The rust came off pretty quick and easy. Nailed it. Look out 2019!”
Justin Rose is four under and Scotland’s Martin Laird is seven under.
