Nadal moves into Rio quarters

Rafael Nadal secured his spot in the quarter-finals of the Rio Open on Thursday courtesy of a 7-5, 6-3 victory over Pablo Carreno Busta.

Nadal was not at his best early on against his compatriot, but a break in the 12th game saw him claim the first set.

The world number three won just 63 percent of points on his first serve in the opener and while his first serve percentage increased in the second set, the ratio of points he won on it decreased.

However, this was enough against the 23-year-old Carreno Busta who was unable to convert any of the three break point opportunities that came his way.

Nadal broke for a second time in the eighth game of the second set to take a 5-3 advantage before serving out the match.

The 28-year-old will now face Pablo Cuevas of Uruguay in the final eight on Friday.

There were also victories on the day for fourth seed Fabio Fognini who beat Pablo Andujar 6-3, 6-2, and Federico Delbonis who surprised eighth seed Martin Klizan 6-2, 6-1.

In the women's draw, top seed Sara Errani defeated Lourdes Dominguez Lino of Spain 6-0, 7-5 to reach the quarter-finals. She is joined there by sixth seed Anna Schmiedlova, but second seed Roberto Vinci and seventh seed Polona Hercog were not so fortunate, going down in the second round.
