Blaine McCallister took the lead at the Buick Classic yesterday in Harrison, N.Y., but could not shake persistent U.S. Open champion Hale Irwin.

"This was kind of a hurdle day for me, in getting by what could have been a bad day," Irwin said after a 69 left him two strokes behind McCallister after two rounds.

Irwin said he remains very busy after his Monday playoff victory in the U.S. Open; so busy, in fact, that he was almost late in getting to the golf course for second round play.

LPGA: In Rochester, N.Y., Amy Alcott birdied the last two holes for a 65 and a two-stroke lead over Patty Sheehan and Kathy Postlewait after two rounds of the Rochester International.

Alcott completed 36 holes at 134, equaling a course record by standing 10 under par after two tours of the Locust Hill course.

Seniors: In Concord, Mass., Chi Chi Rodriguez, who won the Digital Classic in 1986-88, shot 64 for a two-stroke lead over Harold Henning after the first round.

Irish Open: In Dublin, Jose Maria Olazabal's 35-foot birdie putt on the 18th hole gave him a one-stroke, second-round lead over John Bland, Eamonn Darcy and Marc Farry.
