American Brooks Koepka fired a 7-under 65 on Sunday to win the weather-shortened Challenge de Catalunya by three shots.
Koepka finished at 16-under-par 200 for his first Challenge Tour title.
The American had three birdies on the front nine. Around the turn, Koepka eagled the par-5 10th and collected two more birdies en route to a bogey-free round at Golf La Graiera.
Alessandro Tadini carded a 4-under 68 to take second at minus-13. Robert Dinwiddie was one stroke further back after a 68 of his own.
Steven Tiley (65), Andrea Perrino (69) and Luke Goddard (70) shared fourth at 11-under-par 205. Second-round leader Jeppe Huldahl stumbled to a 1-over 73 and fell into a tie for 11th at minus-9.
The event was cut to 54 holes after Saturday's play was washed out by rain.
