33-year-old Koepka won three under 67. This is the fifth major on nine under. Scheffler and Hovland are both two shots behind.
Despite the second-place finish, Scheffler who hit a 65 to get under seven will return to Number 1 in the Official World Golf Rankings. Hovland, on the other hand, had a double bogey on the 16th in order to finish two under 68.
Favorite Rory McIlroy for his part carded 69 to finish joint seventh on two under.
This is the third time in five years that Koepka played a major in New York and won.
“This is incredible,” Koepka said. “I look back at where we were two years ago. I am just so happy right now, this is just the coolest thing.”
“I don’t know how many guys have won five times, but to be with those groups of names is absolutely incredible and I’ll be honest I’m not even sure I dreamed of it as a kid.”
With his five wins, he ties Seve Ballesteros, Peter Thomson, Byron Nelson, John Henry Taylor, and James Braid. He is also only the sixth player to win the Championship at least three times. Others who have done the same are Walter Hagen and Jack Nicklaus (five), Tiger Woods (four), Gene Sarazen (three), and Sam Snead (three).
It is even more remarkable when we remember that Koepka had knee surgery just two years ago.
