The 21-year-old Indian crumbled under the relentless pressure created by Marin to lose 21-19, 12-21, 15-21 in a pulsating final that lasted for an hour and 23 minutes at the Riocentre here.
Sindhu thus became the fourth Indian to win a silver at the Olympics after shooters Rajyavardhan Singh Rathore (2004, Athens) and Vijay Kumar (2012, London) and wrestler Sushil Kumar (2012, London).
Weightlifter Karnam Malleshwari (2000, Sydney), boxer MC Mary Kom (2012, London), shuttler Saina Nehwal (2012, London) and wrestler Sakshi Malik (Rio, 2016) are the other women players from India to have won a medal in Olympics.
