U.S. Open semifinalist Stanislas Wawrinka was among Thursday's second-round winners at the $875,500 Malaysian Open tennis event.
The second-seeded Swiss slugger took care of 2011 Kuala Lumpur runner-up Marcos Baghdatis 6-1, 7-5 on the hardcourts at Putra Indoor Stadium.
In other action involving seeds, 32-year-old No. 4 Jurgen Melzer of Austria handled German qualifier and fellow left-hander Mischa Zverev 7-5, 6-4, No. 5 Frenchman Julien Benneteau topped Spaniard Pablo Andujar 7-6 (10-8), 6-2, and No. 6 Russian Dmitry Tursunov vanquished Spanish wild card Pablo Carreno Busta 6-2, 6-4. Benneteau was last year's runner-up here to Argentine Juan Monaco.
Another second-round result saw surging Portuguese Joao Sousa overcome Uruguay's Pablo Cuevas 4-6, 7-5, 6-0. The 77th-ranked Sousa is seeking his second semifinal in as many weeks. He'll face top seed David Ferrer in Friday's quarterfinals.
The other quarters will pit Wawrinka against Tursunov, Melzer versus Argentine Federico Delbonis and Benneteau against fellow Frenchman Adrian Mannarino.
The 2013 Malaysian Open champion will claim $158,000.
