Argentina's Guillermo Canas won his first ATP tournament since completing a 15-month doping ban when he beat top seed Juan Carlos Ferrero in straight sets to claim the Brazil Open on Sunday.

Canas, ranked 107th in the world, beat the Spaniard 7-6, 6-2 in just under two hours to triumph at the Costa do Sauipe resort on Brazil's north-east coast and collect the seventh ATP title of his career.

Canas's last success was in Shanghai in October, 2004, when he defeated Lars Burgsmuller of Germany.

Canas was originally suspended for two years by the ATP in August 2005 after testing positive for the banned diuretic hydrochlorothiazide (HCT) at a tournament in Acapulco six months earlier.

The ban was reduced to 15 months by the Court of Arbitration for Sport (CAS) which accepted Canas had been given the substance in error by tournament staff.
