Until Scheffler’s late flourish, the top of the leaderboard was tightly contested for so long during an enthralling day in North Carolina, with the lead fluctuating wildly and at one stage, five players sharing top spot.
Overnight leader Jhonattan Vegas began the day two clear but his lead was eroded by bogeys on his first two holes and he finished the day five shots back at six under par.
He is alongside two-time major winner Rahm, who thrust himself into contention with a round of 67.
Fellow LIV golfer and perennial major contender DeChambeau celebrated when he seized the outright lead with three holes of his round to play, but carded a bogey and a double bogey on his way home to shoot a two-under 69.
At the opposite end of the leaderboard, Masters champion Rory McIlroy shot a one-over 72 to end round three 13 shots off the pace.
