Brooks Koepka's PGA Championship title defense got off to a fantastic start Thursday, as he shot 63 to break the Bethpage Black course record.
In just 18 holes, Koepka has established himself as the clear-cut favorite to win the Wanamaker Trophy Sunday.
Only Danny Lee is within a shot of Koepka, who takes the course Friday afternoon for his second round alongside Tiger Woods and Francesco Molinari.
The goal for the rest of the field Friday is to try to get within reach of Koepka to strike at the weekend, but that may be difficult if the three-time major champion replicates his Thursday score.
