Lorenzi stuns seeded Monaco

Paolo Lorenzi upset Juan Monaco to reach the semi-finals of the Brasil Open - the first time he has reached the last four of an ATP Tour event.

The 32-year-old Italian, ranked 114 in the world, looked to have let his chance slip when Monaco bounced back from losing the first set to level up the match in the second.

However, Lorenzi was not to be denied his historic moment and he battled through to a 7-6 (8/6) 6-7 (4/7) 6-4 win in a clash that lasted over two and a half hours.

Lorenzi will now have to produce an even bigger upset if he is to reach the final in Sao Paulo, with top seed Tommy Haas his opponent in the semis.

Germany's Haas did not have it all his own way but battled through his quarter-final tie against Argentinian Horacio Zeballos 6-3 5-7 6-2.

It was a better day for Zeballos' compatriot Federico Del Bonis, who won his quarter-final against Spain's Albert Montanes 6-4 6-3.

And he will face home favourite Thomaz Belluci in an all-South American semi-final after the Brazilian wildcard beat Martin Klizan 6-3 6-3.

It was a dominant display from Belluci, who lost just one point on his first serve in the match.
