PALMA DE MALLORCA, Spain, May 1 (UPI) -- Argentina's Austin Calleri continues to cruise through the field at the $381,000 Mallorca Open.
Calleri, the fifth seed, eased into the quarterfinals Wednesday with a 6-3, 6-1 win over Spain's Juan Balcells at the claycourt tournament.
Calleri has dropped just six games in his first two matches. In the first round, he rolled over Austrian Markus Hipfl, 6-0, 6-2.
In the final eight, Calleri faces Belgium's Olivier Rochus, who ended the run of Spanish wild card Rafael Nadal-Parera, 6-2, 6-2. On Monday, 15-year-old Nadal-Parera became just the ninth player in the Open Era (since 1968) to win an ATP main draw match before turning 16.
David Sanchez of Spain and Mariano Zabaleta of Argentina also square off in the quarterfinals. Sanchez upset compatriot and sixth seed Albert Montanes, 7-6 (7-5), 6-4, and Zabaleta rallied past French qualifier Jean-Francois Bachelot, 4-6, 7-5, 6-0.
The match between top seed Gustavo Kuerten of Brazil and qualifier Magnus Norman of Sweden highlights Thursday's second-round action. Kuerten and Norman met in the 2000 French Open final, which the Brazilian won in four sets.
