Palmer became the first player to make six birdies and two eagles (10 under) in an eight-hole stretch (beginning on the back nine, Nos. 12-1). It was also the longest birdie-eagle streak in Tour history.
Palmer is the fifth player to shoot 27 on a side – Corey Pavin holds the record, with 26 – and just the second to accomplish the feat while recording two pars.
“You have that feeling inside you that there’s no way I can miss this,” he said afterward. “You get in that zone. They could put that pin anywhere they wanted and I could have found it.”
With an inward 34, Palmer shot a best-of-the-week 61 on PGA West’s Nicklaus Course to jump from a tie for 89th to joint seventh. He is three shots back of Matt Kuchar’s lead.
