De Jonge completed the third round at 7-under-par 206 -- one shot better than Tiger Woods and two others -- after the day's activities were delayed by 6 hours to allow for a clean-up from an overnight windstorm.
The Congressional Country Club was socked by severe weather, during which strong winds toppled trees, ripped tents from their moorings and tossed debris throughout the course.
Fans weren't allowed onto the course for safety reasons.
Woods fired a 4-under 67 to grab a share second place at minus-6 with first-round leader Bo Van Pelt (67) and Seung-Yul Noh (69).
Knotted one shot further back were second-round leader Hunter Mahan (73) and Billy Hurley III (66), while Jhonattan Vegas (68) ended at 4-under 209.
