The 32-year-old followed his first-round 74 in the morning with a best-of-the-week 65 to move into contention at the weather-delayed U.S. Open.
Summerhays got his round going with a lengthy birdie at the par-3 eighth hole and added another long birdie from the back fringe at the 14th hole before closing his day with a clutch par save at No. 18.
“They gave us 45 minutes between our rounds so I could kind of hit the reset button,” said Summerhays, who is tied for seventh place and three strokes off the lead. “The putting came around that second 18. The greens were much faster.”
Summerhays started well at last year’s U.S. Open as well, opening with rounds of 70-67 to begin the weekend tied for fifth place, just two strokes off the lead.
Although he ballooned with a 78 on Saturday on his way to a tie for 27th place at Chambers Bay, he said he used last year’s championship as a learning experience.
“I look at it as gaining experience. I continue to improve mechanically and mentally and I’m looking forward to the challenge,” Summerhays said.
