HOBART, Australia -- Patty Schnyder was knocked out of the Hobart International in the first round Sunday by Tsvetana Pironkova 6-2, 6-4.
The 30-year-old Schnyder received a code violation for unsportsmanlike behavior late in the second set for audible obscenities after a prolonged argument with the chair umpire over a line call.
Schnyder, a player's representative for the Australian Open lead up event in Hobart, refused to shake the chair umpire's hand before complaining later about the officiating and the court.
In other matches Sunday, seventh-seeded Alona Bondarenko of Ukraine beat Romanian Monica Niculescu 6-4, 2-6, 6-2, Petra Kvitova of Czech Republic defeated wild card Sally Peers of Australia 6-0, 6-0 and the Czech Republic's Iveta Benesova downed eighth-seeded Tamarine Tanasugarn of Thailand 7-5, 7-5.
