Somdev, who has been going through a poor patch, today lost in the first round of the ATP Shanghai Masters.
In the doubles ATP chart, there was no change in the rankings of Mahesh Bhupathi (6) and Leander Paes (8) but Rohan Bopanna lost a place to be 16.
In the teams' rankings, the Indian Express of Paes and Bhupathi was unchanged at number four and Bopanna-Aisam-ul-haq Qureshi on numbers seven.
There was no change in the doubles ranking of Sania (11) but her team with Elena Vesnina is now standing at six in the WTA race to year-end championship.
Since Sania will be out of action for a days because of a arthroscopic surgery, she and Elena may miss the cut for year-end championship.
Only top four teams compete in the event and the points gap is increasing between Sania-Vesnina (4788 points) and other teams.
Kazakhstan's Yaroslava Shvedova and America's Vania King are at number four with 5530 points while following them are Russian Maria Kirilenko and Belarus' Victoria Azarenka, who have 5490 points.
