La Gomero, Canary Islands – American Brooks Koepka fired a 5- under 66 on Sunday to cruise to a 10-stroke victory at the Challenge de Espana.
Koepka finished his easy victory at 24-under-par 260. The closing 66 matched his worst round of the week as he posted two 64s and two 66s.
The 23-year-old American won for the second time this season, and for the third time in all on the Challenge Tour.
