The Chilean tennis player beat Austrian Sebastian Ofner in two sets after one hour and 14 minutes (6/3, 6/4).
The fourth seed in the singles draw wins the second title of his career, after winning this year in Auckland, beating Kazakhstan's Alexander Shevchenko, Czech Jakub Mensik and Frenchman Gaël Monfils during the week.
"The week has been incredible, fortunately I was able to get the match out of the way and it was very tough for me to close it out against a player who fought so hard. I try to take it one match at a time and that has been the key this year," said Tabilo.
