LONDON — Vasyl Lomachenko of Ukraine opened his second Olympics in the same dominant style that made him the best boxer in Beijing, overwhelming Dominican lightweight Wellington Arias in a 15-3 victory Thursday.
Anthony Ogogo kept the British boxing team unbeaten at home with a stunning victory over world champion middleweight Ievgen Khytrov of Ukraine, the top seed in the Olympic tournament.
With Prince Philip, Prince Edward and wife Sophie cheering from the stands, Ogogo won the entertaining fight on the second tiebreaker, a rare occurrence in amateur boxing.
Germany's Stefan Haertel also pulled an upset, beating heavily favored Irish middleweight Darren O'Neill to advance to the quarterfinals at ExCel arena. O'Neill's defeat was Ireland's first loss in London.
