Lakshya hasn’t been in the best of form recently having made early exits from the Malaysia Open, India Open and German Open.
The 21-year-old had reached a career-best world no. 6 in November last year but couldn’t maintain the momentum in the current season.
Last year, Sen had a rampaging run in the European circuit early in the season, winning the India Open and reaching the finals at Germany and All England.
HS Prannoy continued to remain steady at number ninth spot, while Kidambi Srikanth regained his top 20 spot after climbing two positions.
In women’s singles, PV Sindhu stayed at the ninth spot, while Saina Nehwal, who had skipped the All England Championships, slipped five places to 32nd spot.
Men’s pairing of Satwiksairaj Rankireddy and Chirag Shetty continued at the sixth spot, while women’s combination of Treesa Jolly and Gayatri Gopichand lost a rung to be at the 18th position, despite a semifinal finish last week.
