Reigning British Open champion Jordan Spieth said a "brain fart" caused his late struggles in the first round of the 2018 Open Championship at Carnoustie Golf Links in Angus, Scotland.
Tom Hamilton of ESPN UK passed along Spieth's comments after he played the final four holes in four-over par to post a one-over 72 in Round 1.
"But the misses toward the end were the exact misses that I've been having and I'm working away from," he said. "My swing just didn't quite hold up to the end of my round. Those long irons really hurt me today.
