Sania Mirza's error-strewn serves resulted in her ouster at the first hurdle in the WTA Bangkok Open in Bangkok on Tuesday.
The Indian lost 4-6, 4-6 against sixth seeded Meghann Shaughnessy of America in an hour and 21 minutes in the rain-interrupted first round of the prize money USD 200,000 tournament.
Sania, who slipped to 61st in the latest WTA rankings, double-faulted seven times and committed repeated unforced errors on her backhand.
Shaughnessy, now ranked 43rd, has secured two WTA titles this year. Her career best was in 2001 when she rose to 11th in the rankings.
Some of the first round matches had to be suspended due to rains.
