HARRISON, N.Y., JUNE 24 -- Hale Irwin has his double, and he won't even try for a triple.

"I have other, more pressing matters to attend to next week," the U.S. Open champion said today after he made the Buick Classic at Westchester Country Club his second victory in six days.

And what pressing matters will keep him from competing in next week's tournament? "Going home and being with my family," he said.

"I'm excited . . . But I'm quite exhausted," said Irwin, who came here from winning his third Open in a 19-hole playoff Monday.

"It's been a very, very tense week, a lot of work. But these are the days you look forward to. There aren't many of them. And, at this stage of my career, I probably appreciate these two more than any others. I'm proud of myself in the way I reacted after such an emotional week at the Open."

Paul Azinger, two strokes behind in second, was simply amazed. "It's hard to follow up any win," he said. "I can't imagine what it takes to follow up an Open victory."

It took four consecutive rounds in the 60s, capped by a bogey-free closing 66 and a 15-under-par total of 269 as Irwin became the first player since Billy Casper in 1966 to follow up an Open triumph with a win in the next tournament.

"It shows there's still some life left, still some fun left," said Irwin, who had gone five seasons without a victory before taking the Open.

Azinger, who once closed within one stroke of the lead, was quick to attest to the life left in Irwin, at 45 the oldest man ever to win the Open.

"Being behind, I figured I'd have to shoot a good score to have a chance, and I certainly thought 65 would be good enough. But I'd have had to shoot 63 just to catch him.

"I did as good as I can do," said Azinger, who will defend his title next weekend in Hartford, Conn.

Rookie Kirk Triplett came on with a 66 for third at 272, followed by Ken Green at 67 -- 273. Blaine McCallister, the third-round co-leader with Irwin, faltered to 274.

Irwin's 19th career victory paid $180,000. With a $220,000 check from the Open, he has won $400,000 in six days -- more than in any previous full season in his 22-year PGA Tour career.

Just as he did in celebration of a 72nd-hole birdie in the Open at Medinah, Irwin trotted to the gallery ropes around the 18th green and slapped high-fives with spectators after a last-hole birdie. But it was an extraneous birdie and a much more restrained, sedate visit.

"I'm going to have to think up something new," he said.
