Argentina's Juan Monaco advanced to the quarterfinals of the bet-at-home Cup in Kitzbuhel, Austria, with a 6-3, 6-4 victory Wednesday over Austria's Andreas Haider-Maurer.

Monaco, the highest-ranked player remaining in this clay-court event after top seed Philipp Kohlschreiber lost in the second round on Tuesday to Argentina's Leonardo Mayer, won a match filled with numerous service breaks.

For the contest, Monaco broke Haider-Maurer's serve six times and lost his own on three occasions.

Next up for the 31st-ranked Monaco on Thursday will be Spain's Daniel Gimeno-Traver, a 6-3, 6-3 winner Wednesday over the Czech Republic's Jan Hajek.

In other matches Wednesday, Austrian wildcard Dominic Thiem upset his fourth-seeded countryman, Jurgen Melzer, 7-5, 6-3 and third-seeded Fernando Verdasco won an all-Spanish contest over Guillermo Garcia-Lopez 6-2, 7-6 (9-7).

Dutchman Robin Haase, the tournament's two-time defending champion, routed Germany's Daniel Brands 6-4, 6-1, while Spain's Albert Montañes edged Romania's Victor Hanescu 7-6 (7-2), 3-6, 7-6 (7-5).

This Austrian stop on the ATP Tour dates back to 1894, making it one of the oldest events in men's tennis. EFE
