The Americans have cornered the market when it comes to rookie of the year on the European Tour.
The tour announced Tuesday that Brooks Koepka won the Sir Henry Cotton award as Europe's top rookie.
Koepka finished at No. 8 in the Race to Dubai, helped immensely by his victory in the Turkish Airlines Open. He also had four other top 10s, including the U.S. Open.
Koepka won the award over Tyrell Hatton of England.
Peter Uihlein was European Tour rookie of the year last season. Uihlein and Koepka often traveled together and are roommates when both are home in Florida.
"I've worked so hard this year, and to see the results is fun,'' Koepka said. "To cap the year off with a win in Turkey has made this year special, and it's a goal I've been working for since I was able to come out on tour, and that was the goal starting the year.
"To win rookie of the year, you look at all the guys who have won it, especially last year -- Pete Uihlein -- so at least we can keep it in the house.''
