New York - Russia's Maria Kirilenko slumped to an embarrassing US Open defeat on Saturday before taking out her frustrations on tournament dope testers, saying she was tired of drug controls.
The glamorous 14th seed suffered a 6-1, 6-0 rout at the hands of in-form Romanian Simona Halep in just 51 minutes.
But instead of questioning a performance which saw her hit a paltry three winners, commit 24 unforced errors and drop serve six times, she turned her fire elsewhere.
"Just can laugh about my game today! Going to the doping control, maybe I have something after 0-6! haha sick of it!!!1000times doping doping," tweeted the Russian.
Halep, the 21st seed who has won four titles since June, goes on to face Italy's Flavia Pennetta for a place in the quarter-finals.
