It sound like its Tiger's second shot at 16th hole on Sunday @ the 2005 Masters. He was paired with Chris D'Marco.
Or, you could be thinking of Tiger's eagle putt on the 13th on Saturday @ the 2008 U.S. Open at Torrey Pines.
You can contact the USGA or NBC to see if they have videos available of the 2008 U.S. Open. I don't recall what media outlet telecasted the first two days of that tournament. Don't forget, there was a Monday playoff too.
Also, I am sure that some website on the internet has videos of Tiger's greatest shots.
