Argentine Schwartzman wins Rio Open tennis

Diego Schwartzman ended a two-year wait for his second ATP tour title as he overpowered an exhausted Fernando Verdasco to win the Rio Open.

The Argentine sixth seed was in commanding form, winning 6-2 6-3, against an opponent who appeared to run out of puff after reaching both the singles and doubles finals of the clay-court event.

"I was very patient, solid, intense, I knew he was very tired as he had played both singles and doubles," Schwartzman said of Verdasco who won the doubles final on Saturday.

"It's been two years since I've won a tournament so I am very happy. It was a perfect week for me."

Schwartzman broke serve three times in the first set as the eight-seeded Spaniard produced a string of unforced errors.

Once Verdasco squandered four break points at 2-2 in the second set, he appeared to wilt under pressure and Schwartzman ran away with the match.

The 25-year-old will enter the world's top 20 for the first time on Monday.
