Hale Irwin, the U.S. Open champion who won't go away, birdied his last two holes and advanced into a tie for the third-round lead yesterday in the Buick Classic.

Irwin, 45, who won his third U.S. Open in a 19-hole playoff on Monday, made up two strokes with a 68 and completed 54 holes at 203.

He was tied at 10 under par at Westchester Country Club in Harrison, N.Y., with Blaine McCallister, the second-round leader, who shot 70. McCallister retained a share of the top spot only with a 20-foot birdie putt on the final hole.

"I'm fighting fatigue," Irwin said. "The adrenaline surge is gone now. I need to cycle in a new one. I had some loss of concentration . . . a bit of trouble finishing today.

The problems developed, he said, after a long wait -- "at least five minutes" -- in the 15th fairway.

LPGA: Amy Alcott recovered from a double bogey on the 14th hole to keep a two-shot lead in the LPGA Rochester (N.Y.) International.

Alcott, who broke a course record at 10 under par for 36 holes, set another by completing 54 holes at 14 under. With a 68 at Locust Hill, matching the round of her two closest pursuers, Patty Sheehan and Kathy Postlewait, she has a 202 total with a round to go.

Seniors: Mike Hill shot 68 and tied Chi Chi Rodriguez at 135 for 36 holes in the 54-hole Digital Seniors Classic at Nashawtuc Country Club in Concord, Mass. Rodriguez, who won this event thrice, 1986-88, followed his tournament course record of 64 on Friday with a 71. Defending champion Bob Charles had 67 to tie Harold Henning at 136.

Irish Open: Marc Farry and Jose-Maria Olazabal share the lead after three rounds at Portmarnock. Farry, who would be the first French winner on the European tour in 20 years, sank a 40-foot birdie putt on the 18th green for a 210 total.
