Three wins in his last five starts. Looks like Hale Irwin has found his game.

That could be bad news for the rest of the Senior PGA Tour.

Irwin, the senior circuit's player of the year the last two years, was at his overpowering best yesterday. He closed with a 7-under 65 for a 21-under 267 total, winning by seven shots over Graham Marsh in Dearborn, Mich.

"I hardly know what to say. The last two rounds were exceptional," said Irwin, who played the final 36 holes in 15 under. "I just blitzed them."

Marsh started the day four strokes off the pace and shot a 68. John Jacobs bogeyed the final two holes for a 67 and finished third at 275.

"It was an awesome display of touch, control, aggression," Marsh said. "I mean, you name it: Hale did just about everything he wanted to do over the last two days."

Irwin started the day 14 under, but left everyone behind with birdies at Nos. 1 and 3. He made the turn at 17 under with a birdie at No. 9 -- starting a string of four holes he would play in 5 under.

"That just tends to slam the door on people who may be getting close," Irwin said.

The rest of the field might as well have been playing a friendly Sunday nassau. Nobody was going to catch Irwin, not even with clean-and-place rules brought on by a heavy overnight rain.

The victory earned Irwin $300,000 of the $2 million purse put up by the sponsor, Ford Motor Co.
