Henrik Stenson has opened up a four-shot lead over Adam Scott at the halfway stage of the TOUR Championship at East Lake Golf Club in Atlanta.
The Swede, who was one clear following yesterday's 64, took two more shots to complete his second round, with the only blemish on his scorecard coming at the par-four 10th hole.
Both men occupy the top two positions in the FedEx Cup standings, while Tiger Woods (+4) will be hoping that they falter for him to take the $10m (£6.2m) cheque.
Jordan Spieth is in third place on his own on five-under-par, followed by Justin Rose, Dustin Johnson and Billy Horschel on four-under.
