* Micheel holes out with three-iron from 239 yards
* Regrets not seeing his ball fall into the cup (Adds detail, quotes, byline)
PEBBLE BEACH, California, June 20 (Reuters) - Shaun Micheel had just one regret after recording only the second albatross at a U.S. Open when he holed out with a three-iron at the par-five sixth hole in Sunday's final round.
The 2003 U.S. PGA Championship winner struck his second shot from 239 yards at the 523-yard, uphill hole and moments later the gallery crammed behind the green cheered its approval.
"The only disappointment I have is that I didn't see it go in," the 41-year-old American told reporters after carding a one-over-par 72 at Pebble Beach to finish at nine-over 293 in the second major of the year.
"I just knew the line for the green and I hit the best three-iron I've hit in a long time. And I hear people kind of moaning and groaning and I hear this roar and it was just the greatest feeling ever.
"It was certainly something that I will remember for a long time," said Micheel, who had surgery on his left shoulder last year and played the remainder of the season on a medical extension.
"To make a double-eagle on Father's Day at the final day of the U.S. Open, the way my career has kind of been going the last couple of years, it makes me feel very, very special.
"It's a lasting image that I'll take with me forever, to pick that ball out of the hole. I've got it hidden away in my secret pocket in my golf bag. I'll probably give that one to my mom."
Micheel, who struck a brilliant seven-iron approach to two inches on the final hole to seal a shock victory at the 2003 PGA Championship, played this week's U.S. Open in honour of his cancer-stricken mother Donna.
Taiwan's Chen Tze-Chung, popularly known as T.C. Chen, scored the first double eagle, or albatross, at the U.S. Open in the opening round of the 1985 tournament at Oakland Hills Country Club.
Chen holed out with three-wood from 256 yards at the par-five second, only to post a quadruple-bogey eight on Sunday to blow his lead and, eventually, the championship. (Editing by Greg Stutchbury; To query or comment on this story email email@example.com)
