FORMER Filipino world champion Johnriel Casimero made it look easy and scored a fourth round stoppage of a weight-drained Luis Nery in their highly-anticipated featherweight showdown in Nagoya, Japan on Saturday. The 37-year-old Casimero came out firing right away and knocked down Nery three times in the opening round to set the tone for the one-sided match at the Aichi Tokoname, Aichi Sky Expo.
