The hole was No. 17, the year was 2001, and the golfer was Andrew Magee. But the circumstances were anything but normal.
Magee, just an average driver of the ball, didn't think he'd be able to reach the green on the 332-yard par-4. So he didn't wait for the group ahead to clear the green. Instead, he teed up, and - steaming over a double bogey two holes earlier - muscled up. He let her rip, and the ball went farther than he expected.
So far that it ran up onto the green while the group of Steve Pate, Gary Nicklaus and Tom Byrum were still putting. The ball raced past Pate and Nicklaus, who both saw the ball, then clanged off the putter of Byrum, who was caught by surprise.
The ball ricocheted off Byrum's putter, caromed about eight feet, and dropped right into the cup. Hole-in-one. Still the only par-4 ace on the PGA Tour, and surely one of the more unusual aces of any kind on the tour.
