2015 Waste Management Phoenix Open.
There were high hopes for this Ryder Cup rookie going into Hazeltine and he did not disappoint. Koepka overpowered Hazeltine -- and his opponents -- with his remarkable long game, compiling an impressive debut record of 3-1-0. His three points collected for the USA tied him for second-best on the team. Koepka put an exclamation point on his brillant week with a 5&4 rout of Masters champion Danny Willett in Sunday's singles matches. This was the largest margin of victory in the singles session.
