A few notes from around the boxing world:
• Middleweight Ryota Murata (7-0, 5 KOs), 29, a 2012 Olympic gold medalist, will make his American debut on Nov. 7 in Las Vegas on the undercard of the Timothy Badley Jr.-Brandon Rios fight at the Thomas & Mack Center. Murata is scheduled to face Gunnar Jackson (22-6-3, 8 KOs), 29, of New Zealand, in a 10-rounder. Murata has trained in Las Vegas and when he turned pro under a co-promotion of Japan’s Teiken Boxing and Top Rank the plans was always for him to begin his career in Japan before eventually coming to fight in the United States. “We’re really excited about having him fighting in the U.S. on a card like this,” Top Rank vice president Carl Moretti said. “This is all part of the plan to expose him in the U.S. and continue to build him. He’s getting better each fight.” Another 2012 Olympic gold medalist, featherweight titlist Vasyl Lomachenko (4-1, 2 KOs), of Ukraine, is also on the card in a defense against Mexico’s Romulo Koasicha (25-4, 15 KOs).
• Golden Boy announced it has signed Puerto Rican junior middleweight Jorge Melendez (29-5-1, 27 KOs) and middleweight Bastie Samir (14-0-1, 14 KOs), a 2008 Olympian from Ghana it used to promote. “Golden Boy’s roster showcases the best upcoming and experienced fighters and the addition of Jorge and Bastie only furthers our mission of bringing the best talent aboard our team,” Golden Boy CEO Oscar De La Hoya said. “Jorge and Bastie are fighters to be feared in the ring, we are excited to be with them as they continue their paths to becoming champions.” Meldnez, 26, has big power but a shaky chin. He has been stopped in three of his five losses and is 1-2 in his last three bouts. Samir, 29, has not fought since October 2013.
• Showtime announced it will debut a one-episode “All Access” to chronicle the buildup to the Dec. 5 all-Brooklyn, New York, showdown between secondary middleweight titlist Daniel Jacobs and former titleholder “Kid Chololate” Peter Quillin on Nov. 17 (8:30 p.m. ET/PT). Jacobs and Quillin will meet Dec. 5 (Showtime, 9 p.m. ET) at the Barclays Center in Brooklyn.
