Luke Donald is two shots off the lead at the end of round two of the Tour Championship in Atlanta, Georgia.
The Englishman hit a two-under-par round of 68 to leave him six-under, while Australian Adam Scott leads the field after a round of 65 left him eight-under.
Donald is the only player in the top five who is in contention to win the FedEx Cup and the $10m (£6.4m) top prize based on points accumulated from competitions won over the year.
The 33-year-old's fellow countryman Justin Rose hit a round of 75 to leave him four-over, while overnight leader Keegan Bradley hit a one-over 71 to leave him three shots off the lead.
