Well-ordered Swiss player Martina Hingis complained on Monday that drug testers don't respect players' schedules as they go about their surprise business at the Acura Classic.
The five-time Grand Slam champion, playing at the event for the first time in five years after her return to the game, said that a surprise test on Sunday intruded on her practice time and threw off her scheduling as she plays at her first event since Wimbledon.
"I was just tested Sunday again out of the blue," the 25-year-old Swiss player said.
"They should look at a player's schedule. They just come in and screw up your whole day. They could come at the end of the day or in the morning, but not in the middle of the day when you have training scheduled. It's not a big difference if it's in the morning, the night or the next day," Hingis said.
"It's not like anything's going to go away," she said.
Hingis said that drug testers this weekend also ignored a "do not disturb" sign on the door of Maria Sharapova's room as they tested the Russian at the weekend.
"How far can they go?" an irate Hingis asked.
"I'm not not afraid of [the] test, but they could at least respect my private hours," she said.
