Lakshya Sen has advanced to the quarterfinals of the Singapore Open 2026 after Thailand’s world No. 2 Kunlavut Vitidsarn retired hurt just two rallies into their Round of 16 clash at the Singapore Indoor Stadium. The Thai star looked uncomfortable from the very first point and appeared to struggle badly with movement before eventually pulling out because of a suspected back issue. It was an unfortunate end to what was expected to be a blockbuster contest, with Lakshya progressing to the last eight after leading 2-0 in the opening game.
