PNC Championship leaderboard: First round scores of PGA Tour's hit-and-giggle

Matt Kuchar and his son Cameron combined to shoot a 15-under 57 to open up a two-shot lead on day one of the PNC Championship. 

The Kuchars raced out of the blocks, putting circles on their scorecard at the opening three holes. 

Five more birdies saw them make the turn in 28. 

Their back nine at the Ritz-Carlton Golf Club in Orlando, Florida, was equally impressive, with the duo making seven more birdies. 

They lead John Daly and his son John Daly II by two strokes. A host of teams, including Nelly Korda and her father Petr, are three back. 

Daly and his son are more than likely to be the Kuchars' biggest challengers. They captured the title here four years ago with a record score. 

"He's the horse and the saddle," Daly said of his son. "That's all there is to it."

"We didn't get off to the best of starts. We were even par after two and the Kuchars got hot quick and we kind of fed off them a little bit. 

"It was just one of those great days, good ball striking.

"Like I said, if I could have given Little John a few better reads on the greens I think we could have went a little lower.

"He played great. I never really play that great, but that's all right in my life right now."

The reigning champions, Bernhard Langer and his son Jason, are not out of the hunt but will need something extra special tomorrow if they are to defend their title. 

The PNC Championship is the final tournament of the calendar year, bringing together past major winners and members of their family. 

Notable absentees this year include Tiger Woods and his son Charlie. Tiger, who turned 50 today, is still recovering from his latest back surgery. 

The PNC Championship has a total purse of $1m, with $200,000 awarded to the winning team.
