PEBBLE BEACH, Calif. — Tiger Woods felt good about the start at the Pebble Beach National Pro-Am until he looked at the leaderboard.

With six birdies, he opened with a 4-under 68 at Spyglass Hill.

With virtually no wind, and as gorgeous conditions as can be found on the Monterey Peninsula, he was far from the only player who was filling up his scorecard with birdies.

Dustin Johnson, with a small measure of revenge on the third hole at Pebble Beach, made two eagles and saw a third chance at eagle land on the edge of the cup. He wound up with a 9-under 63. Former U.S. Amateur champion Danny Lee also made two eagles at Pebble for a 63.

Over at Monterey Peninsula, Charlie Wi had an outside chance at 59 without even knowing it. Wi wasn’t aware the Shore Course was a par 70, so being 8 under through 13 holes didn’t get his attention. He made one birdie the rest of the way for a 9-under 61.

They were atop the leaderboard, followed by a record-tying performance by Ken Duke — 28 on the back nine at Pebble.
