Former champion P V Sindhu progressed to the women’s singles second round but Lakshya Sen went down fighting to world number one Viktor Axelsen at the Singapore Open Super 750 badminton tournament here on Wednesday.

Sindhu had last won a BWF title at Singapore two years back and she entered the tournament after signing off with a runner-up finish at Thailand Open last week.

Up against world no. 21 Line Hojmark Kjaersfeldt of Denmark, the Indian registered a 21-12 22-20 win in a 44-minute opening round to set up a mouth-watering battle against Rio Olympic champion Carolina Marin of Spain.
