Turning out to play the dead fourth rubber, N Sriram Balaji lost to Pedja Krstin in straight sets as India ended the Davis World Group Play-off tie against Serbia without a single win, losing 0-4, here on Sunday.
Since the tie was already decided in favour of the hosts, who had taken an unassailable 3-0 lead, India fielded Balaji in place of Ramkumar Ramanathan.
Serbia also changed the nomination, playing Krstin in place of Dusan Lajovic.
Balaji, who is more focussed on the doubles, lost 3-6 1-6 in 66 minutes on indoor clay courts at the Kraljevo Sports Venue.
The two sides agreed not to play the fifth rubber.
"It was not a bad match for me. In every service game I had game points but I was not sharp enough to take them. Even most of the return games were close. The scoreline look easy for him but we had long games," Balaji told PTI.
"Before going into the tie, we thought we had a chance of beating them. But they came up strong in every match."
