GSTAAD, Switzerland, July 24 (UPI) -- No. 2-seeded Stanislas Wawrinka claimed a straight-set win Wednesday that lifted him into the quarterfinals of the Swiss Open.
Wawrinka posted the first break of the match to win the first set and then won the first four games of the second before Gimeno-Traver rallied and forced the tiebreaker. Wawrinka was able to move ahead midway through the tiebreaker and closed things out from there.
Wawrinka's win led a four-match sweep by seeded players Wednesday.
No 4-seeded Juan Monaco had the clearest result, beating Guillermo Garcia-Lopez 6-1, 6-2 without facing a break point. Monaco won half of the points when receiving serve and nearly three-quarters off his serve.
Fifth-seeded Feliciano Lopez took out Andrey Kuznetsov 6-4, 6-3, firing off nine aces and saving the only break point he faced.
Wawrinka will go against Lopez and Monaco takes on Youzhny in Friday's quarterfinals.
