Bethesda - Billy Horschel made three birdies in his opening four holes and hung on for a 3-under 68 for the best score among the early starters at the AT&T National on a cloudy day at Congressional.
With thick rough on a long course, par was at a premium.
Jim Furyk, Nicolas Colsaerts and Ben Kohles were at 69.
No one else managed to break 70.
Horschel tied for fourth in the U.S. Open two weeks ago at Merion.
Lucas Glover had a 72 and said it was a very quiet morning — not because Tiger Woods wasn't around to attract a big crowd, but because not many players were making a lot of birdies.
