Jordan Spieth told his caddie he could feel himself collapsing Sunday during his implosion at the Masters.
The 22-year-old appeared on track to defend his green jacket until he found trouble on the back nine, following two bogeys with a quadruple bogey at the par-3 12th. Spieth found water twice to put himself in trouble as he saw a five-shot lead slip away, eventually finishing three behind winner Danny Willett.
