To be in Augusta on the 50th anniversary of his father's Masters victory, Billy Harmon feels lucky.

But to have his player in contention after 54 holes, well, that's icing on the cake.

Harmon, the youngest son of the late 1948 champion Claude Harmon, is the caddie for Jay Haas this week. After Saturday's 71, Haas is just four strokes behind leader Fred Couples.

Ironically, Haas' playing companion Saturday was defending champion Tiger Woods. His swing coach is Butch Harmon, Billy's oldest brother.

``I didn't look for Butch, but I think I saw him once,'' Billy Harmon, a teaching pro himself, said after the round. ``I had a job to do.''

Sibling rivalries aside, both men were pulling for their players Saturday.

``He wants Tiger to win by a shot and I want Jay to win by a shot.'' Harmon said. ``(But) he thinks the world of Jay Haas.''

Fifty years ago, Claude Harmon won his only major as a professional, besting Cary Middlecoff by five shots in the Masters. The elder Harmon birdied Nos. 6 and 7 during the final round, then sealed the victory with an eagle on the eighth hole.

He was the first Georgia native to win the title, but he was better known as a teaching professional, both at Winged Foot Golf Club in New York and Seminole Golf Club in Florida. He often practiced with Ben Hogan at Seminole, then would drive up to Augusta for the Masters each spring.

His greatest legacy, however, might be that each of his four sons are teaching professionals. In addition to Butch and Billy, Craig is the pro at Oak Hill Country Club in Rochester, N.Y., and Dick is the head professional at River Oaks Country Club in Houston.

But this week, all four Harmon brothers are finding the golden anniversary of their father's greatest moment a bit emotional.

``It was special. There are moments in your life and you reflect, and I reflected a lot today,'' Billy said. ``It's a pretty neat thing that your father won the Masters.

``Augusta National and the Masters have been pretty damn good to the Harmons,'' he continued. ``I'm really touched by it. You'd like to think the old guy was looking down with a smile on his face.''

Haas, whose uncle Bob Goalby won the Masters in 1968, got the best of Woods early in the day. His 32 on the front nine gave him a share of the lead with Couples, but a fat 8-iron on the dangerous par-3 12th produced a double bogey.

``I just hit a bad shot,'' said the Greenville, S.C., resident. ``First one of the week, and I kind of lost my confidence after that. I just need to work it out.''

Haas got a stroke back with a birdie on the 15th, but bogeyed Nos. 16 and 18 to close the day.

The nine-time winner on the PGA Tour has a habit of playing well at the Masters, finishing in the top 10 in five of his 16 trips. He finished third in 1995, thanks to a second-round 64.

``I don't know,'' Haas said when asked why he fares so well at Augusta. ``I love this place.''

That makes two of them.
