Sergio Garcia and Matt Kuchar were cruising along in their quarterfinal match on Saturday at the WGC-Dell Technologies Match Play, but everything changed as they were finishing up on the 7th green.
Putting for par to win the hole and tie the match, Garcia left his putt just inches from the hole, and never looked in his opponent's direction before and attempting - and missing - his tap-in so quickly that Kuchar didn't have a chance to concede the bogey putt.
Kuchar told the rules official that he would've given the putt to Garcia, but since the rule states that can't be done retroactively, Kuchar won the hole and went 2 up in the match.
