Sindelar holed out a 3-wood from 241 yards on the par-5 fifth hole Saturday for a double eagle, the rarest shot in golf and only the third in PGA Championship history.
'The fun part is it started getting in my mind about five years ago that I hadn't had one. I couldn't retire without one,' Sindelar said, still smiling almost four hours later.
'I would have taken it in a practice round. Instead I get to do it after making the cut, in a major. And at Medinah.'
It was the first double eagle at the PGA Championship since Per-Ulrik Johansson at Riviera in 1995. The only other albatross was by club pro Darrell Kestner at Inverness in 1993.
Gary Evans was the last player to make an albatross in any major -- the first round at Royal Troon two years ago in the British Open.
The most famous double eagle in any major came at the 1935 Masters, when Gene Sarazen holed out with a 4-wood from the 15th fairway at Augusta National, a shot that enabled him to get into a playoff and beat Craig Wood the next day.
'Double eagles are just so difficult,' Sindelar said. 'Far less chances and far more luck.'
Sindelar's drive left him 241 yards to the cup. At 2 over for the tournament, he was just hoping to get close to the hole and give himself a chance for birdie. Instead, he got a little piece of history.
'It was such a blur,' he said. 'It was very exciting for me. I almost duffed my next tee shot!'
Sindelar, who began the day even for the tournament, finished with a 1-over 73.
Sindelar has had holes-in-one, including one on the par-3, 17th at The Players Championship. It was only the fourth hole-in-one on the famed island green.
But a double eagle is something else.
'It'll be the only ball I've ever saved,' Sindelar said. 'I'm not even going to clean it. It's going to have Medinah dirt on it.'
