A few notes from around the boxing world:

• Although Top Rank promoter Bob Arum hopes to finalize a very attractive junior lightweight fight between featherweight titleholder Vasyl Lomachenko (5-1, 3 KOs), who would move up one division, and former featherweight titleholder Nicholas Walters for the main event of a June 11 HBO-televised card from the Theater at Madison Square Garden in New York, Arum said it has been slow going. The reason: He is far apart on the money with Walters (26-0-1, 21 KOs). But Arum said he is confident he would be able to work it out. Popular Puerto Rican lightweight Felix Verdejo (20-0, 14 KOs), one of boxing's elite prospects, is ticketed for the co-feature against an opponent to be determined on the eve of the annual Puerto Rican Parade in New York.

• Gilberto Mendoza Sr., the president of the WBA from 1982 until his resignation due to poor health in 2015 at the organization's annual convention, died on Friday in Venezuela after a long battle with cancer. He was 74. "It is with a heavy heart that the World Boxing Association regrets to announce the passing of its president emeritus, Francisco Gilberto Mendoza," the organization announced. Mendoza, who boxed as an amateur, was succeeded as president by his son, Gilberto Jesus Mendoza.

• Promoter Sampson Lewkowicz announced on Monday that Jonathan Guzman (20-0, 20 KOs), of the Dominican Republic, and Mexico's Daniel Rosas (20-2-1, 12 KOs) will meet in an elimination bout for No. 2 in the IBF junior featherweight rankings, moving the winner a step closer to a mandatory title shot. They are scheduled to meet on April 29 in Atlantic City, New Jersey. While the winner would move closer to a shot at unified titleholder Carl Frampton, he is moving up to featherweight to challenge Leo Santa Cruz this summer, meaning there is a good chance the Guzman-Rosas winner would wind up fighting another contender for the vacant belt should Frampton stay at featherweight, which is likely.

• In a match between veteran welterweights, Francisco "Chia" Santana (23-4-1, 12 KOs) will face Ed Paredes (36-5-1, 24 KOs) in the main event on UniMas' "Solo Boxeo Tecate" on April 2 at Oceanview Pavilion in Port Hueneme, California. Lightweight Luis Ramos Jr. will face an opponent to be determined in his first fight since signing with Top Rank.
