Tom Watson, the 60-year-old who's the only player to participate in all five U.S. Opens at Pebble Beach, carded his best round of the tournament, a 1-under 70 that leaves him at 6 over for the tournament.

Watson, who made the cut on the number Friday, had his best stretch of the week on Saturday when he birdied the drivable par-4 fourth to begin a string of four birdies in nine holes. At that point, he was 3 under for his round.

But he dropped a couple of shots coming in, including a bogey at the 17th when he hit a poor chip from just off the green. He then missed a makeable birdie putt at the 18th.

"I flubbed the chip," Watson said about his shot at the 17th. "I had a chip that was in the loose fescue grass around there. It's unpredictable and I tried to hit and expose a shot and it went about a foot.

"... It was kind of a disappointing finish because I bogeyed 17 and missed the birdie at 18. But all in all, I'm very happy with shooting 70 here at Pebble Beach."
