Star Indian boxer Vijender Singh returned to winning ways in style as he notched a knockout win over Ghana's Eliasu Sulley in Raipur on Wednesday. Vijender, who delivered India's first Olympic and men's world championship medals in boxing, showed his class as he dominated Sulley. Vijender landed the winning blow in the second round of what was to be a six-round contest to leave the reigning national West Africa Boxing Union Champion dazed. The 36-year-old Beijing Olympics bronze medallist needed only five minutes and seven seconds to dispatch the Ghanian, who till now had a 100 per cent knockout record.
