Brisbane, Australia (SportsNetwork.com) - Third seed Gilles Simon was an upset victim, while former world No. 1 Aussie star Lleyton Hewitt was an upset winner Thursday at the Brisbane International tennis event.
Romanian qualifier Marius Copil drove out the 19th-ranked Frenchman Simon 7-5, 6-3, while the unseeded world No. 60 Hewitt upended sixth-seeded Spaniard Feliciano Lopez 7-5, 6-3 at Queensland Tennis Centre.
Also on Thursday, eighth-seeded Jeremy Chardy got past fellow Frenchman Nicolas Mahut 7-5, 6-7 (4-7), 6-3 and Aussie wild card Samuel Groth overcame lucky loser Pierre-Hugues Herbert 4-6, 7-6 (7-3), 7-6 (7-5) at this hardcourt Australian Open tune-up. The Frenchman Herbert replaced fourth- seeded Kevin Anderson in the draw when the tall South African pulled out, citing a viral infection.
