Sania Mirza could not end the season on a high as she and her partner Nuria Llagostera Vives were sent packing from the WTA Kremlin Cup by the American pair of Raquel Kops-Jones and Abigail Spears, in Moscow.
Third seeds Sania and Nuria, who had ended runners-up at the prestigious China WTA event recently, lost the hard fought second round match 5-7, 4-6 after battling it out for one hour and 41 minutes.
The two players struggled to hold serve in the first set as the Indo-Spanish pair lost serve thrice and the Americans twice.
In the second set, Sania and Nuria failed to cash in on the break chances that dented their chances to make a comeback.
Out of four, they could convert just one and dropped their serve twice to crash out of the tournament.
