BETHESDA, Md. (AP) Steve Marino used to consider it a treat the few times he played Congressional as a teenager. It was a thrill on Thursday to play bogey-free in the first round of the AT&T National and shoot 5-under 65 for a one-shot lead. Marino, who grew up a half-hour away in Fairfax, Va., birdied three of his opening four holes, never had a par putt longer than 5 feet and finished off his round with an 8-foot birdie to be in the lead after any round for only the second time in his career. Jeff Overton, Frank Lickliter, Rod Pampling and Bob Estes opened with 66s.
