BEACHWOOD, Ohio — Having waited two decades to finally win his first big tournament, Michael Allen has his eyes on another prize.

"This gives me the exact scenario I want," he said with a laugh after shooting a 3-under 67 yesterday to win the Senior PGA Championship by two shots over Larry Mize. "I'm going to be the first guy ever to win a senior tour event BEFORE he wins his first PGA Tour event."

The 50-year-old journeyman ended his lengthy victory drought with two late birdies to capture the first Champions Tour major of the year — in his debut on the over-50 tour. He almost didn't accept the special exemption because he still has his regular tour card and considered playing in the richer Byron Nelson.

Allen, who finished at 6-under 274, collected $360,000 for his first win of any kind since the 1998 Greater Austin Open on the Nationwide Tour. His only other win came in the 1989 Bell's Scottish Open on the European Tour.

Mize had a 67 and held a two-stroke lead at the turn. But he was 1 over on the back nine while Allen was going 2 under to steal the win.

"I just caught the wrong guy on the wrong week," Mize said.

Allen became only the fourth player to win a major championship in his Champions Tour debut, joining Roberto De Vicenzo (1980 U.S. Senior Open), Arnold Palmer (1980 Senior PGA Championship) and Jack Nicklaus (1990 Tradition).

Bruce Fleisher had a 67 to finish third.
