"It's 36 holes. You've got the No. 1 player in the world chasing you, you've got x-number of other players that are outstanding players", Kokrak said.
There were many more low numbers shot on Friday, including Billy Horschel's five-under 65, which featured birdies on his final three holes.
It was on the par-5 16th where the real damage was done as he had to take three tee shots on his way to a nine after sending his first two attempts out of bounds. With a 3-over total and needing at least one birdie, Spieth finished with consecutive pars.
The 23-year-old Spieth also missed the cut last week in The Players Championship.
Among those players missing the projected cut were Hunter Mahan, Bryson DeChambeau, Bryce Molder, J.B. Holmes, Ryo Ishikawa of Japan, Graham DeLaet of Canada, former PGA Championship victor Y.E. Yang of South Korea and Ryan Moore.
Kokrak finished with a nice par save after driving way right at the 18th.
Brooks Koepka leaned in for a closer look at his ball buried in deep rough when a critter he couldn't identify caused him to jump back with a bit of a startled look. He tied for second at the Wells Fargo Championship in his return to the tour two weeks ago, and then had a career-best 12th place finish at The Players Championship.
Masters and defending Nelson champion Garcia, ranked fifth, had just one birdie in a 73 that left him tied for 93rd. On the next hole, he had to bend his second shot around tree from the rough and saved par.More news: Haryana board (BSEH) Class 10 results will not be declared on Saturday
Thompson is playing her third tournament since losing the ANA Inspiration in a playoff after being penalized four strokes for a rules violation that a TV viewer spotted. 3-7 on Kingsmill Resort's River Course. She waited out an hour rain delay in the middle of the round. Top-ranked Lydia Ko was two back at 67 along with Sarah Jane Smith and Giulia Molinaro.
In Gee Chun (66) and Vicky Hurst (67) were 7 under, and Angela Stanford (66), Shanshan Feng (67) and Brittany Lincicome (70) were another stroke back.
BIRMINGHAM, Ala. (AP) - There's a four-way tie for the lead through one round of the Regions Tradition in Birmingham, Ala.
Parel, who went through Q-school in 2016, shot a 66.
Johnson two-putted from 90 feet on the 18th hole to stay a part of his group. Hahn's first four birdies were inside 10 feet.
Quiros added a second-round 64 to his opening 63 to sit on 15-under-par after 36 holes. No problem for the former World No. 1, who picked it off the path and got up-and-down for birdie. "Felt like there were a lot of times I hit really good shots that didn't end up in good spots". It was just in long grass and I wouldn't be able to flop it over.
"[I was] just trying to do too much, trying to move up the leaderboard instead of just letting it come to me on this course", Spieth said afterwards.
