ATLANTA — Dustin Johnson hit his stride at just the right time and it paid off in a big way.

Johnson finally won the FedEx Cup on Monday by holding his nerve, hitting just enough fairways and making a few key putts when his lead began to shrink. He tapped in for birdie on the last hole for a 2-under 68, giving him a three-shot victory over Justin Thomas and Xander Schauffele in the Tour Championship.
