David Duval and stepson Nick Karavites shot an 11-under 61 on Saturday to take the first-round lead in the PNC Father/Son Challenge.
They birdied Nos. 1, 3-7, 13-16 and 18 to open a one-stroke lead over Fred and Taylor Funk in the two-day, 20-team scramble event at Ritz-Carlton Golf Club's Grande Lakes.
The Funks got off to a fast start with birdies at Nos. 1 and 2 and an eagle at 3, where Taylor — a member of the University of Texas golf team — hit a 3-wood from 265 yards to 30 feet and made the putt. They added birdies at Nos. 5, 7, 10, 11, 15 and 18 for a 62.
Retief and Leo Goosen, Raymond and Robert Floyd, Stewart and Connor Cink, Bernhard and Christina Langer, and Mark and Shaun O'Meara were tied for third at 63. Fan favorites John and Little John Daly shot 64.
