Thomas & Mack Center, Las Vegas - Japan's 2012 Olympic gold medal winner Ryoto Murata (8-0, 5KOs) made his American debut with a ten round unanimous decision over Gunnar Jackson (22-7-3). The scores were 99-91 98-92 97-93.

Jacokson took the fight to Murata in the first round, throwing with both hands and looking to get through the Japanese fighter's tight guard. In the second, Murata started digging with hard hooks to the body and Jackson was feeling the sting of those punches.

Murata got tagged a few times in the third, but took the punches well and continued to dig with shot to the body and used his jab as a range-finder to set up other punches. Murata continued to box, dig to the body and outwork Jackson to the final bell.

In his first bout since losing a twelve round decision to Nicholas Walters in June, featherweight contender Miguel Marriaga (21-1, 18KOs) put in a workman-like effort to win an eight round unanimous decision over Guillermo Avila (15-5). All three judges saw it 80-72.

Marriaga outworked Avila in practically every round, but never once had the gutsy Mexican in serious trouble at any point in the contest.

Avila was coming off a July TKO defeat to  Romulo Koasicha, who later tonight faces WBO featherweight champion Vasyl Lomachenko in the HBO televised co-feature.

Junior welterweight Mike "Yes Indeed" Reed (17-0, 10KOs) stopped Rondale Hubbert (10-4-1) in the seventh round. Reed dominated the fight, dropping Hubbert in the seventh with a good right hand and then battering him against the ropes until referee Kenny Bayless jumped in to wave it off.

Opening things up, Lithuanian Olympian Egidijus "Mean Machine" Kavaliauskas (10-0, 9KOs), who is trained by Robert Garcia, demolished Jake Giuriceo (17-5-1, 4KOs) in the first minute of the first round.

Egis dropped Giuriceo right away with the first bomb that connected. Giuriceo made it up, but referee Russell Mora felt he was too hurt to continue the fight. The fight was called at exactly 1:00 of the first.

Two fights ago Giuriceo went the eight round distance with current WBC junior welterweight champion Viktor Postol.
