The expected weather is fortuitous for Tiger Woods. He wouldn't have been in the final group with Francesco Molinari. Now that he is, there could be the intimidation and high-pressure factors in play today.
Also, Molinari is an enigma. 1.) He was a caddy for his brother in the past. 2.) He mainly seems to be in contention in majors, which may indicate that he loves and feeds off pressure. He in fact beat Tiger in the British Open last year (Tiger was in a different group, and finished second).
