Top seed Sania Mirza was ousted in the first round of the $145,000 Moroccan Grand Prix clay-court tennis tournament on Tuesday.
The Indian ace was beaten by qualifier Ma Emilia Salerni of Argentina 6-2, 7-5.
Earlier, Sania put aside her three-month long injury lay-off to win her first round doubles match.
She and Vania King of the United States came back 4-7 in the super tie-break to win 6-3, 5-7, 10-8 against Alla Kudryavtseva of Russia and Olga Savchuk of Ukraine.
It was the 20-year-old's first competitive match in nearly three months as she was out of action due to a ligament injury.
"It's always good to win a match when you're coming back after so long, especially a close one," Sania said.
Sania, who played with Liezel Huber of South Africa most of last season, said she combined well with Vania.
"I think it's a good thing we got the toughest unseeded team first. We played well together for our very first time as a team.
"There were a few hiccups, but at the end of the day it's good to come through."
Sania said her knee "was holding up very well".
The Hyderabadi girl said she felt a mix of excitement and nerves in her first match after a long break.
"While I was playing today, I was thinking about how much I've missed the feeling of competing," she said.
