Jose Acasuso silenced the local fans when he defeated hometown favourite Nicolas Massu 6-4 6-3 in the final of the ATP Movistar Open in Vina del Mar.

It was a perfect weekend for the 23-year-old Argentinian who won the doubles title with Sebastian Prieto against top seeds Frantisek Cermak and Leos Friedl on Saturday.

The third seed was just too powerful for Massu as he lifted his third ATP title in the US$380,000 claycourt event.

"I knew I needed to improve my game to beat Nicolas and I did," Acasuso said.

"I think I prepared well for the match with my coach and things worked out perfect,'' Acasuso added.

"I am sorry for Nico Massu since he was playing at home in front of his people."

Massu was gracious in defeat but sad to have disappointed his hometown fans.

"I want to congratulate Acasuso for this win,'' Massu said. "He is a great person and a great player and he really deserves it.

"I was a bit tired since I played over seven hours in the last two days, but that doesn't mean that he didn't deserve the win.

"I am sad that I lost at home, in my home town, because I really wanted to win. For me this tournament is big and important but unfortunately it did not happen."
