World championships bronze medallist Nishant Dev (71kg) recorded a comprehensive 5-0 victory over Christos Karaitis of Greece to reach the quarterfinals of the first World Olympic boxing qualifier late on Sunday.
Nishant, the lone Indian left in the event, took the three rounds of the pre-quarterfinal bout with 5-0, 4-1, 4-1 verdicts.
The Indian southpaw began cautiously before displaying his combinations and counterattacks to gain ground as the Greek got a standing count during the contest.
