The knock on Brian Harman has been that he thinks to much. He's even admitted as much himself. It happened when he took a one-shot lead into the final round of the 2017 U.S. Open, when he was no match for Brooks Koepka that Sunday.
So when Harman, who hasn't won a tournament anywhere in six years, launched his drive on the par 5 fifth hole into a gorse bush, forcing him to take a penalty drop, suddenly his Sunday stroll to victory in the 151st British Open was in doubt. A bogey, his second on the day, meant the five-shot lead he'd taken into the round was down to three.
