Jordan Spieth, rule book victim. Jordan Spieth and Patrick Reed were on the 12th hole of their afternoon four-ball match against Louis Oosthuizen and Jason Day, and Oosthuizen was putting for eagle from off the green. The putt rolled well past the hole and — because the Americans already had conceded Day’s birdie-3 for that hole — Spieth went over to pick up Oosthuizen’s ball. Here is the "incident" that got Jordan Spieth disqualified from the 12th hole. Spieth and Reed were forced to forfeit the hole as a result, and Oosthuizen and Day took a 1-up lead even though they lobbied with the rules official that Spieth and Reed not be penalized.
