Klizan took charge from the start breaking early and never looked back.
He then saved four break points in the fourth game and built a 5-1 lead.
Gimeno-Traver dropped his serve in the third game of the second set and Klizan went up 5-2. He fended off three other break points to serve out the match.
This was Klizan's third tournament win having previously won titles in St. Petersburg in 2012 and Munich last year.
