– Ukraine’s Vasyl Lomachenko knocked out Roman Martinez to grab the World Boxing Organization 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 three knockouts — and became the fastest fighter to gain world titles in two weight divisions. “I need more fights. It’s not enough fights for me. I need fights to get better,” he said. Lomachenko compiled an amateur record of 396-1 with Olympic gold medals in 2008 and 2012.
