I posted this a little while ago, and perhaps it bears repeating here. Plenty of guys have shot good or great rounds at Tiger at the end of majors. Here are some examples:
1998 Br. Open Mark O'Meara: 68, beat Tiger by two even though TW shot 66
1999 PGA Sergio Garcia: 71, pushed Tiger to last hole
2000 PGA Bob May: 66, forced Tiger to sink birdie on 72nd to tie
2001 Masters David Duval: 67...72 hole total 274...Tiger had to shoot 68 and 272 to win
2002 PGA Rich Beem: 67, beat Tiger even though Woods staged furious rally on final 9
2005 Masters Chris DiMarco: 68, forced playoff, beat all others by 7 strokes
2005 U.S. Open Michael Campbell: 69, played near-flawless final 9, only player to match par for 72 holes
2006 Masters Phil Mickelson: shot 69, played near-flawless golf final 18 to win
2006 Br. Open Chris DiMarco: 68, Tiger had to shoot 67 (low round of day) to win by 2 at -18
2007 Masters Zach Johnson: 69, low round of the day, to win
2007 U.S. Open Angel Cabrera: 69, 2nd-best round of the day, to win
Don't forget, Jack often benefited from poor to indifferent play from others, and downright gifts. Arnie shot 74 in the playoff at Oakmont. Sanders missed the 3-footer to win at St. Andrews. Seve and Norman both collapsed in 1986. Brewer shot 78 in the playoff at ANGC in 1966, and Jacobs could do no better than par. In 1972 at Augusta Jack could only manage 74 the final round, but won anyway because the best his competitors could do was 73. Same year at Pebble Jack shot 74 the last round, but won by three when 2nd place Bruce Crampton shot 76.
