Cuba's Roniel Iglesias has breezed into the last 16 of the Olympic light-welterweight tournament with victory over Cesar Villarraga Aldana of Colombia.
The first round was very nip and tuck until Iglesias stepped up the pace and began to let his fists go, taking an 8-3 lead.
Iglesias once again settled into the action in the second round before overwhelming Villarraga with a string of crisp combinations.
The Cuban controlled the contest for its duration and powered his way to a 20-9 verdict.
