Zeballos beats Russian teen Rublev in Swiss Open 1st round

GSTAAD, Switzerland (AP) Horacio Zeballos of Argentina beat Russian teenager Andrey Rublev 6-4, 7-6(1) in the Swiss Open on Monday to earn a second-round match against top-seeded David Goffin of Belgium.

Zeballos took the only break point he needed in the first set against his 17-year-old, wild-card opponent. After exchanging service breaks in the second, Zeballos cruised through the tiebreaker.

The 14th-ranked Goffin was elevated to top seed when French Open champion Stan Wawrinka withdrew from his home event last week.

Defending champion Pablo Andujar of Spain will face Dusan Lajovic in the second round of the clay-court event after the Serb beat French qualifier Calvin Hemery 7-5, 6-2.

Federico Delbonis of Argentina beat Swiss wild card Marco Chiudinelli 6-4, 6-2, and Denis Istomin of Uzbekistan beat Frenchman Maxime Teixeira 6-0, 6-4.
