OK, so maybe there are three rounds left, but Tiger Woods doesn’t usually go low on the first day of a major.
But when he does (courtesy of the AP):
Key statistic: Woods has won the last four majors he had at least a share of the lead after 18 holes.
Noteworthy: The last two times Woods opened bogey-free in a major were the U.S. Open and British Open in 2000. He won them by a combined 23 shots.
So yeah, it’s over.
