I was watching the 30th anniversary broadcast of Gary Player's win in 1978 yesterday. There were a ton of guys making big moves up the leaderboard that day, too. 1998 was another great one, with O'Meara holding off Couples and Duval.
It's just sad that there doesn't seem to be a 65 or 66 out there to be had on Sunday anymore. Immelman shot 75 and won by 3 -- that's not the Masters I remember. It's another US Open in April.
