Spain's Tommy Robredo won his second successive tournament on Sunday when he beat Argentina's Juan Monaco 7-5, 2-6, 7-6 in the final of the Buenos Aires Open.
The third seed followed up last week's win in Costa da Sauipe, Brazil, by clinching his ninth ATP title.
"I am very happy for having won back-to-back titles for the first time in my career," said the world number 17.
"I trained hard to be able to play well in consecutive weeks."
Robredo earned the opening set's only service break in the 11th game but lost momentum following a 90-minute rain break after the first game of the second set.
Unseeded Monaco, who beat top seed David Nalbandian on Saturday, took advantage to break serve three times in a row and level the match.
Both players broke serve twice in the third set before Robredo squandered two break points at 5-5. The set went to a tiebreak, which the Spaniard clinched with his fourth match point.
