PONTE VEDRA BEACH, Fla. -- Colt Knost had an opportunity to set the Stadium Course record at TPC Sawgrass on Friday -- only to three-putt the final green after missing a par putt from 5 feet.
Knost, 30, the 2007 U.S. Amateur champion, had 10 birdies and a bogey and was bidding to become the first player to shoot 62 at the home of the Players Championship.
He had hit his approach to the par-4 18th green to 43 feet, but then his birdie putt came up short.
"I was nervous on the tee shot because I hit it in the water there yesterday and made double," said Knost, who was aware of the record. "... I was honestly fine over the first putt, thought I hit a pretty good one, and it just was a lot slower than I thought.
"I was nervous on the 4- or 5-footer, however far it was. But honestly, I hit a good putt. I hit it on the left edge, and it just stayed there and lipped out."
Knost, who has never won on the PGA Tour and has no top-10 finishes in 15 starts this season, hit all 18 greens in regulation, taking only 27 putts for the round.
Day, the first-round leader, had yet to tee off Friday.
