With five of the world's top six players in the field, Triplett stole the show with birdies on six of his last nine holes. He finished his round at the Quail Hollow Club by making a 30-foot birdie putt.
Woods, who has been battling swing problems throughout the year, settled for a 3-under 69 while current Masters champ Phil Mickelson had a 70.
Thursday's round was the first on the tour in three weeks to be started and completed on the day it was scheduled. Foul weather disrupted play throughout the Houston and New Orleans events, both of which ended on a Monday.
