American Jason Kokrak won his second tournament on the PGA Tour with an uneven round of 70 enough to take the Charles Schwab Challenge in Fort Worth, Texas.

Kokrak started the final round a shot behind compatriot Jordan Spieth, but the three-time Major winner dropped shots on three of the first four holes.
