I think Rich is referring correctly to a different incident where Clarke was a participant, though not the key participant. DLIII, playing in the Sunday singles against Clarke, hit a shot into the rough and it was near a sprinkler head. Many, including the announcers IIRC, felt DLIII would find a way to take a stance where he would be afforded relief, which could have put him in the fairway. He did not, chose to play the ball as it lie (lay? I can never remember that one), and the US captain made a point of saying how proud he was that Davis followed both the letter and spirit of the rule (paraphrasing).
