Forced to make a fresh start after his opening win was wiped off the record books, unfazed Indian ace Lakshya Sen stamped his class to defeat Julien Carraggi of Belgium in straight games in their men’s singles group match of the Olympic Games’ badminton competition here on Monday.

The 22-year-old Sen, who is making his Olympic debut, beat Carraggi 21-19, 21-14 in the Group ‘L’ match that lasted 43 minutes.
