The 42-year-old former Arizona State star made a 4-foot birdie putt on the par-4 ninth — the hole where he missed the putt for a 59 on Thursday — and overpowered the par-5 15th for an eagle, hitting to 4 feet after a 358-yard drive.
“I felt really comfortable on the tee box, so I kind of let one go and caught a hold of it and ended up having 191 to the pin,” Mickelson said. “It was only 186 to the front, and I hit a hard 8-iron. There was a little bit of helping wind.”
After a par on the par-3 16th that drew boos from the rowdy fans on the stadium hole when his tee shot trickled into the fringe, he drove the green on the 344-yard 17th and two-putted from 70 feet — leaving his eagle try a foot short — for birdie.
Bradley also eagled the 15th, hitting a 350-yard drive and a 7-iron approach to 8 feet.
“I just smashed a driver down there,” Bradley said. “I had been hitting 3-wood and I’m driving the ball so well that I just decided to rip driver down there.”
He birdied the 16th, hitting to 5 feet.
“It reminds me of when I go to Fenway Park,” Bradley said. “There’s always like a murmur. … It’s really cool. I dig it. I wish there was more holes like that out here.”
Haas began play on No. 10 and made the turn at 6-under 30.
“We all know the way the course is playing, if there’s no wind on the weekend, you’ve just got to keep making birdies,” Haas said.
