Monaco avoids upsets at Stuttgart

STUTTGART, Germany, July 12 (UPI) -- Second-seeded Juan Monaco avoided a rash of upsets Thursday to make it to the quarterfinals of the Mercedes Cup.

Monaco was a 6-2, 6-3 winner over Tobias Kamke in the clay-court tournament and will next face qualifier Pavol Cervenak.

Cervenak was one of the day's surprise winners, taking out eighth-seeded Tommy Haas 6-4, 6-4. Haas recorded the biggest victory of his career last month when he stunned Roger Federer to win a Wimbledon tune-up.

No. 3 seed Bernard Tomic was also an upset victim, losing to Thomaz Bellucci 7-6 (8-6), 6-3.

In another second-round match Thursday, Cedrik-Marcel Stebe defeated former Mercedes Cup champion Jeremy Chardy 4-6, 7-6 (10-8), 6-3.
