Johnson goes top in North Carolina
Zach Johnson was the big mover during the third round of the Wyndham Championship in North Carolina.
The former US Masters champion picked up five birdies in his first 14 holes to climb to the top of the leaderboard on 10 under par.
That took Johnson one shot ahead of 20-year-old Jordan Spieth and overnight leader Patrick Reed, who was two over through 10.
Spieth briefly led on 10 under after back-to-back birdies on the eighth and ninth but he quickly fell back with a bogey at 10.
Spieth is in contention for his second PGA Tour title of the season after beating Johnson and David Hearn in a play-off to win the John Deere Classic in July.
It remained a congested leaderboard, with US duo Matt Every and Brian Harman sitting on eight under.
John Huh saw his title hopes dealt a blow with a triple-bogey seven at the second as he slipped to seven under.
Defending champion Sergio Garcia needed a good day having started six shots off the lead.
Birdies at the 12th and 15th repaired some early damage but that only took him to four under, surely too far back to challenge.
