World number one archer Deepika Kumari survived some anxious moments before getting past US teenager Jennifer Mucino-Fernandez 6-4 to sail into the pre-quarterfinals of the women's individual section and keep Indian medal hopes alive at the Tokyo Olympics.

Deepika seemed to feel the pressure initially as she started off hitting the red-zone, capping a poor seven at the floodlit Yumenoshima Park.  

Deepika lost the first set by one point but she bounced back strongly with three 10s in a row to take a 4-2 lead. She, however, failed to wrap up the match in the fourth set as she misfired a six in her second arrow.

The 18-year-old American made it 4-4, winning the set by one-point (25-24). In the winner-takes-all fifth set, Deepika had two 9s to start with before finishing with a poor 8.  

Needing a 10 in her last arrow to force a shoot-off, Jennifer signed off with a nine in what was a promising campaign for the American teenager.

Earlier, Deepika sailed into the second round with a facile 6-0 win over lower-ranked Karma of Bhutan in her opening match.
