HOBART, Australia(AP) 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.
