Ace Indian shuttler Saina Nehwal regained the No 1 position in the international rankings after China's Li Xuerui dropped a couple of rungs to third in the latest list, issued on Friday.
She skipped last week's Singapore Open Super Series, but gained in the rankings after Xuerui also pulled out from the tournament, leading to loss of two places in the women's singles chart.
Elsewhere, P V Sindhu dropped out of the top 10 and is placed 12th this week after losing three spots.
In the men's rankings, K Srikanth retained fourth place, while P Kashyap rose a rung to 14th following a semi-final finish in the Singapore Open.
H S Prannoy, a quarter-finalist at Singapore, dropped a rung to 15th.
