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.

His win Monday at Conway Farms gave Johnson the No. 4 seed going into Tour Championship, giving him a clear shot at the FedEx Cup and its $10 million prize.

“It’s hard to grasp the last two weeks of golf,” Johnson said. “It’s not like you have to win every week to win that FedEx Cup. You’ve just got to win at the right times, or play well at the right times. And I like the momentum I have for next week.”

Johnson’s 10th career win came at the expense of Jim Furyk, who endured another dose of final-round disappointment. Furyk, who had a one-shot lead, has failed to win the last six times he had at least a share of the lead going into the last round.

He holed a 12-foot birdie putt at No. 10 to build a two-shot lead, but played the last eight holes in 2-over and wound up with a 71 to finish alone in third.

Furyk had to settle for a slice of history Friday as the sixth player in PGA Tour history with a 59. Only three players in that exclusive club went on to win — Al Geiberger is the only player to win when the 59 was not in the final round.

“I don’t know if I used them all up on Friday and knocked them all in or what, but I just wasn’t able to get the putts to go,” Furyk said.

Johnson wasn’t the only player who felt like a winner Monday.

Luke Donald, a member at Conway Farms, was No. 54 in the FedEx Cup and was on the verge of being left out of the top 30 players who advanced to the Tour Championship until a late run for a 66 and a tie for fourth. That moved him up to No. 29 to get him into East Lake.

Watney was at No. 34, and he went from playing his way into the top 30 to nearly winning the tournament.

Watney closed with a 64 and was tied for the lead until Johnson made an 18-foot birdie putt out of the first cut on the 16th hole, and a 12-footer for birdie on the next hole.
