LAKE FOREST, Ill. — Zach Johnson is having a September to remember, and there's still one very big week to go. In one tournament, he made a 25-foot birdie putt on his final hole to earn the last spot on the Presidents Cup team. In the next one, Johnson made a bunch of big putts in the final round of the rain-delayed BMW Championship for a 6-under 65 for a two-shot victory over Nick Watney.
