Not long after the second round of the U.S. Senior Open was postponed due to unplayable conditions yesterday, the USGA was criticized over its plan to complete the championship with 36 holes tomorrow.

A steady downpour that started Thursday night and continued into midday yesterday dumped about three inches of rain on Bellerive Country Club in St. Louis, leaving the course swamped.

The second round is set for today, and those who make the cut are scheduled to play the final two rounds tomorrow.

"That is a decision that surprised me, to be honest with you," said Leonard Thompson, who was four strokes behind first-round leader Peter Jacobsen, who opened with a 6-under-par 65.

"With the age of the guys, to ask these guys to walk 36 holes is a gutsy decision. You could have some guys go down out there."

USGA Championship Committee Chairman Walter Driver said extending the tournament into Monday wasn't really an option. The tournament is using hundreds of volunteers, many of whom must return to work Monday.

* BUICK OPEN: Vijay Singh kept a share of the lead at the Buick Open, and there were plenty of big names in contention after two rounds in Grand Blanc, Mich.

Singh, Jim Furyk and Billy Andrade were tied for the lead at 11 under.

John Daly matched his best round of the year with a 64 and was tied with three others one stroke behind the leaders. Tiger Woods had a 4-under 68 and was among four others another shot back.

The cut was 4 under, matching the low for the season on the PGA Tour.

* WOMEN'S BRITISH OPEN: Annika Sorenstam's surge to the top of the leader board stopped suddenly on the back nine in Sunningdale, England.

The defending champion moved within two strokes of the lead, but she faltered late, with two bogeys and zero birdies in the second half of her round. Sorenstam settled for a 1-under 71 that left her tied for fifth at 5-under 139, four strokes behind leader Karen Stupples.

Stupples had another bogey-free round, this time a 2-under 70 that mover her to 9-under 135. Beth Daniel (69) and South Korea's Jeong Jang (68) and Seol An Jeon (69) are tied for second at 6-under 138.
