New lines for boxing this weekend have popped up in the last 24 hours. Of special interest is the continued activity around the “Premier Boxing Champions” name, as the promotion has taken over the MGM Grand on Saturday and Sunday with two boxing events. Airing on Saturday on NBC, the “PBS” series headlines with Adrien Broner vs Shawn Porter. The live event has eight total fights, and a line has appeared for the Lightweight bout between Miguel Angel Mendoza and Robert Easter. Sat 6/20 – MGM Grand Garden Arena – Las Vegas, Nevada Lightweight 10 rounds – Miguel Angel Mendoza +1200 Robert Easter -2600 The “Premier Boxing Champions” stay at the MGM Grand for Sunday afternoon boxing on CBS in the United States. The main event of that fight features undefeated Cuban Rances Barthelemy (22-0) faces battle tested veteran Antonio DeMarco (31-4-1) in a 10 round bout at Super Lightweight. DeMarco is coming in as a (+350) underdog to Barthelemy, who returns at (-530). There is no over/under posted. Like most talents coming from the island of Cuba, Barthelemy comes with a huge amateur back-ground and he has fought professionally for six years now. Barthelemy has campaigned in several weight classes, gathering regional and minor titles at Lightweight before moving on to win the IBF World Super Featherweight title. He is now at a higher weight class, but he has already notched ins at this weight. DeMarco is a former 2x WBC World Lightweight titleholder and he is a very experienced veteran. DeMarco is coming off a loss to Jessie Vargas last November in a failed bid to win the WBA version of the World Super Lightweight title. In that match he lost a relatively close decision to the undefeated Vargas, and that formula appears to be in play again as he faces the highly skilled, undefeated Cuban. The other match getting action from the “PBC” Sunday matinee event is a welterweight 10 round bout between undefeated Sammy Vasquez (18-0) and once beaten Wale Omotoso (25-1). The line sees Vasquez installed as a (-365) favorite, with the comeback on Omotoso at (+255). No over/under is listed. For Vasquez this is a step-up fight, as it is just his second time fighting away from his northeast home base in Pennsylvania. Back in March of 2013, he fought in Las Vegas on the undercard of Gary Russell Jr vs Vyacheslav Gusev, that is his only experience on the road. Omotoso is from Nigeria, but he fought most of the early part of his career in Australia. He has been in the United States fighting on high-level events since 2011. Back in September of 2012, he was on the Sergio Martinez vs Julio Cesar Chavez Jr fight at the Thomas and Mack center in Vegas.
