ATLANTA (AP) -Rory McIlroy has captured the biggest cash payout in golf history by surging past Brooks Koepka (KEHP’-kuh) in the final round of the Tour Championship at East Lake to win the FedEx Cup and its $15 million prize. One shot behind, McIlroy took the lead with a three-shot swing on No. 7 and never let Koepka or Xander Schauffele catch him. McIlroy closed with a 4-under 66, a score that would have won the Tour Championship in any scoring format. He finished four shots ahead of Schauffele. McIlroy joined Tiger Woods as the only players to win the FedEx Cup twice since it began in 2007. Meanwhile, Atlanta police say six people injured by debris from a lightning strike at the Tour Championship on Saturday have been treated and released. A powerful bolt struck a 60-foot pine near the 16th fairway about 30 minutes after the third round was suspended because of storms in the area.
