Aaron Baddeley and Hunter Mahan are tied in the lead going into the final day's play at the Tour Championship in Atlanta, Georgia.

Australian Baddeley hit a round of 64, while American Mahan's score of 66 put both players on nine-under-par.

As it stands, Mahan tops the FedEx Cup standings and is in line for the $10m (£6.4m) top prize.

Donald had previously posted two strong rounds, and he is still in with a chance of winning the richest prize in sport.
