Jordan Dempsey admitted he was doing a little scoreboard watching when he came up the 18th fairway at the Peoria Ridge Golf Course.

Dempsey held a precarious one-stroke lead over one stroke victory over Australians Andrew Tschudin and Bronson La'Cassie in the Buffalo Run Casino Classic.

"I thought I had a one-shot lead, but those boards aren't always right," said Dempsey, a Ole Miss product. "I was waiting for them to change it. I told my dad I was going to ease it down in there. If it goes in, great. If not, I would take my chances of someone making a birdie and tying it."

He nailed a 6-foot birdie putt then waited as the Australians parred No. 18 to seal his first professional win.

"It feels great," said Dempsey, who had rounds of 67 and 65, then shot sounds of 67 and 65 (31 on the final nine) during a marathon Sunday that was forced when Saturday's round was washed out by a rain-soaked course.

His 24-under par 264 countered a 23-under 265 logged by Tschudin and La'Cassie.

He pocketed $33,500 with the win.

"I am sure my wife has a plan for it," Dempsey quipped. "I still have to call her and let her know."

Dempsey had eight birdies and one bogey during the critical final round. At the same time, Tschudin - who had led the first three rounds - closed with a 70.

He had two bogeys, including a critical one on No. 16 that allowed Dempsey to take the lead for good.

"It was disappointing, but at least I had the lead for 3 and 3/4 of the time," Tschudin said. "I shot myself in the foot on 16."

La'Cassie had rounds of 65 and 68 Sunday.

In addition to Saturday's washout, Sunday's final round was held up for about 45 minutes because of lightning.

"I thought we were going to be done after 18 today since we had more rain rolling in," Dempsey said. "I figured I was going to finish sixth (where he was after three rounds). But it started clearing up. I told Dad (Gary Dempsey, who caddied Sunday) that I needed something special - and here comes a 31."

Blaine Peffley of Lebanon, Pa., Tim Ailes of Gahanna, Ohio, and Brandon Brown of Shelbyville, Ky., finished in a tie for third at 21-under par 267. Peffley - who won the Loma Linda Classic last week at Joplin, Mo. - fired the low round of the tournament on Sunday with a 10-under par 62. Brown and Ailes closed with 65 and 69, respectively.

Among the Oklahomans in the tournament, Broken Arrow's Brett Myers led the way, finishing with a 14-under 274.

Brad Risenhoover of Stigler closed with an even-par 72 Sunday and finished at 10-under par 278. He's the cousin of Miami High School head football coach Chris Risenhoover.

Grant Downey of Sand Springs rounded out the contingent with a 7-under par 281.
