ATLANTA — Chris Kirk and Billy Horschel have little in common except a clean card of 4-under 66 at the Tour Championship and their chances at the biggest payoff in golf. Kirk and Horschel, the top two seeds going into the FedEx Cup finale at East Lake, played in the final group and traded birdies — neither of them made a bogey — over four hours in steamy weather to share the lead. They need only to win the Tour Championship to claim the FedEx Cup and its $10 million bonus.
