What Happens After A Pga Tour Player Shoots A 59? Jake Knapp Is About To Find Out.

If form holds, Jake Knapp will probably shoot something around a 69 on Friday at PGA National in the second round of the Cognizant Classic.

That's the average score - well, 68.64, to be exact - for those coming back to work on the PGA Tour a day after joining golf's under-60 club.

Knapp set a course record at a defenseless PGA National on Thursday with a 12-under round of 59, the 15th sub-60 round in PGA Tour history. The second round - with a bit more wind in the forecast, which could be a major change from Thursday's combination of no breeze and soft greens - will begin Friday morning with Knapp leading by four strokes over Daniel Berger, Russell Henley and Sami Valimaki.

"I like this golf course," Knapp said after finishing the 59 on Thursday. "I'm comfortable on it. When the wind was down, I knew that it was going to be gettable. When this place gets windy, it can get really challenging, so it's one of those where you know you have to play pretty aggressive when it's not windy, so I just did my best to do that."
