Ukraine's Vasyl Lomachenko knocked out Roman Martinez on Saturday to grab the World Boxing Organisation super featherweight world title - his second world belt in just his seventh pro bout. Two-time Olympic gold medallist Lomachenko sent Puerto Rico's Martinez sprawling on his back with a devastating left uppercut-right hook combination to win by knockout at 1:09 of the fifth round.
He improved to 6-1 with 3 knockouts - and became the fastest fighter to gain world titles in two weight divisions.
