Brooks Koepka got up-and-down for birdie from behind the 18th green to complete a bogey-free Sunday morning at the Tour Championship and set up a wild finish for $15 million in the FedEx Cup.

Koepka had two bogeys in five holes of the third round when it was suspended Saturday because lightning struck a 60-foot pine at East Lake and injured six people who had been standing near the tree. They were treated and released from hospitals that night.

Koepka had a 2-under 68 and was at 15-under par.
