BETHESDA, Md. — Roberto Castro didn’t qualify for the US Open this year. He felt as if he played in one at Congressional on Thursday in the AT&T National.
Castro ran off three straight birdies late in his round for a 5-under 66, giving him the lead on a tough day that didn’t yield too many low scores considering the cloud cover and relatively soft conditions.
Billy Horschel, who tied for fourth in the real US Open two weeks ago at Merion, began his day with a 50-foot birdie putt, added a pair of birdies over the next three holes and then hung on for a 68. That was the best score among the early starters. Bud Cauley had a 68 in the afternoon. Full story for BostonGlobe.com subscribers.
