SOUTHAMPTON, N.Y. - Jay Haas was like any other father at the U.S. Open at Shinnecock Hills as he watched his 22-year-old son take on golf's toughest test.

And he showed the kid how to get it done.

Thirty years after playing his first U.S. Open, Haas took advantage of unusual calm on the links-styled course with a 4-under 66 that gave him a share of the clubhouse lead with Shigeki Maruyama when play was suspended.

"There's nothing you can say about it. He's good," Bill Haas, who was 3 over with one hole left, said of his dad. "... Most kids can beat their dads, but I can't."

No one could beat Haas, 50, in an opening round filled with unexpected turns - most because of weather that included everything but wind, the one element that sharpens teeth at Shinnecock Hills.

"The easiest day you'll ever see out here," said Corey Pavin, who was 1 under with five holes to play.

Haas overcame a bogey on his second hole by making birdies at the par-3s on the back nine, including a 40-footer on the 17th.

"It was just the kind of day that you had to feel you could be aggressive at a U.S. Open," Haas said.

Angel Cabrera also was 4 under through 12 holes when the first round, delayed more than two hours by rain, was halted because of fog. Play will resume at 7 a.m. today.

Among the 57 players who did not finish were Phil Mickelson (15 holes) and Vijay Singh (14 holes), both at 2 under and without a bogey.

Not everyone who played early had an easy time.

Tiger Woods had to save par five times from the bunker to finish at 72. Ernie Els took a double bogey at No. 11 (his second hole) but salvaged a 70. Davis Love III made two triple bogeys and shot 76.
