CARMEL, Ind. — Graham DeLaet was in Boise a few weeks ago when he dropped $150 to buy a long putter from Wide World of Golf.

Now the former Boise State standout is hoping the purchase leads to some serious cash — and even more credibility on the PGA Tour.

On his final hole Thursday, DeLaet rolled in a 38-foot putt for an eagle, pushing him into a tie for the lead with Rory McIlroy, Bo Van Pelt and Webb Simpson at the BMW Championship. They all fired 8-under 64s, while Tiger Woods and Vijay Singh are one shot back with 65s.

DeLaet has quietly become the Cinderella of the FedEx Cup. He started the playoffs ranked 106th until he tied for fifth at The Barclays. Now he’s No. 60 but still facing elimination — only the top 30 qualify for next week’s Tour Championship.

Right now, DeLaet is projected to end up sixth — with three rounds to play on a long and wet course that is surrendering low numbers.

“Coming into the playoffs, even coming into the year, I was just hoping to make the playoffs, coming off an injury and all that, and I just feel like it’s kind of a bonus, and I’m just going to try to roll with it the next couple weeks,’’ DeLaet said.

IN BOISE ON MONDAY: DeLaet is scheduled to compete in the $50,000 Michelob Ultra Shoot-Out at Hillcrest Country Club, a prelude to the Albertsons Boise Open (Sept. 13-16).
