It appears some players are starting to figure out the tough course at The Olympic Club in the 2012 U.S. Open. Casey Wittenberg and Angel Cabrera are in the clubhouse with rounds of -3 and -1, respectively, and Webb Simpson is two-under through 10 holes.

No one has yet to catch up to the leaders — Jim Furyk, David Toms and noted golf enthusiast Tiger Woods — who sit at -1 for the tournament, but the field is creeping in. Simpson bogeyed the ninth hole, but birdied No. 10 to find himself just four strokes back of the leaders. Woods and Furyk tee off at 6:05 p.m. ET, and those closest to them will be starting soon, so things are starting to get interesting.
