David Duval and stepson Nick Karavites shot a 10-under 62 on Sunday to win the PNC Father/Son Challenge by a stroke.
Duval and Karavites finished at 21-under 123 in the scramble event at Grande Lakes to hold off 2013 winners Stewart and Connor Cink, newcomers Retief and Leo Goosen, and Fred and Taylor Funk.
The Goosens and Cinks shot 61, and the Funks had a 62. Team Goosen missed 10-foot birdie putts on 18 that could have tied them for the lead.
Event newcomers John and Little John Daly shot 63 to tie for ninth at 17 under.
