In Thursday's first round, the native of Kaneohe, Hawaii, made one bogey with seven birdies on the way to 6-under-par 66.
The bogey came at the par 4 sixth hole while his round ended with birdies on four of his last six holes.
Wilson, who missed the cut in five of eight tournaments to date this season, is searching for his second win on the PGA Tour. He won the now-defunct International in Castle Rock, Colo., in 2006.
Five players, including Steve Elkington, are tied for fifth place at 4-under 68.
