DETROIT -- Jake Knapp shot an 11-under 61 to break a Rocket Classic record that stood for less than a day, becoming the first PGA Tour player to break 60 and shoot a 61 or lower in the same season.
Knapp started the second round 130th in the 156-player field after opening with a 72. He surged into contention Friday with nine birdies and an eagle in a bogey-free round.
"I was just probably upset all night and this morning, so I think that maybe helped a little bit," he said.
