Day 2 of the U.S. Open has begun with 155 players all chasing leader Michael Thompson.

Especially Tiger Woods.

The 14-time major champion began Friday three strokes behind Thompson and tied with four others in second at 1 under. Woods and Thompson both have afternoon tee times.

Calm and cool conditions under a thin layer of fog already burning off gave The Olympic Club a majestic backdrop of San Francisco's steep hills when the first groups teed off shortly after 7 a.m. It could be the last time most players enjoy the serene setting.

The U.S. Golf Association decided this year to eliminate the 10-shot rule in making the cut. Starting at this year's championship, the cut will be the top 60 and ties.
