Never seen more ups and downs in the final round of a major -

Blowing a 3 shot lead - by the fourth hole, then what happens on 13 then birdie-eagle-birdie-birdie on 14, 15, 16 and 17 (and he came within an eyelash of acing the 14th) to shoot a 69 and finish at -12 and beat Kooch by 3 (who also shot a 69 and then day before shot a 66 and still lost a stroke to the leader...)

It was unbelievable
