Arum claims he's talking to Showtime about Lomachenko/Postol card

A few notes from around the boxing world:

  • Top Rank promoter Bob Arum is frustrated by HBO’s lack of interest in a card he is trying to sell featuring featherweight titlist Vasyl Lomachenko against former titlist Nicholas Walters and junior welterweight titlist Viktor Postol against -- Arum hopes -- Adrian Granados. So even though Top Rank has done all of its premium cable business with HBO for several years, Arum said on Wednesday in New York, where he is promoting the Terence Crawford-Hank Lundy card on Saturday night (HBO, 10 ET/PT), he is talking to Showtime about the card, even though Arum has often been severely critical of Showtime Sports head Stephen Espinoza. But now Arum is turning his ire on newly promoted HBO Sports boss Peter Nelson for his lack of interest in the card.

    It remains to be seen if Espinoza, who has had a poor relationship with Arum, is interested in his proposed doubleheader. Virtually all of Showtime’s fights in recent years have involved fighters from the stable of manager Al Haymon.

  • Blue-chip lightweight prospect Robert Easter Jr. (16-0, 13 KOs), 25, of Toledo, Ohio, will take a step up in competition to face former junior lightweight titlist Argenis Mendez (23-3-1, 12 KOs), of the Dominican Republic, on April 1 (Spike, 9 p.m. ET) at the DC Armory in Washington, D.C.

    Mendez, 29, has won two fights in a row, including a decision against former lightweight titleholder Miguel Vazquez in October, since losing his belt by unanimous decision to Rances Barthelemy in July 2014. The fight will serve as the co-feature to the previously announced Premier Boxing Champions main event in which junior welterweight titlist Adrien Broner (313-2, 23 KOs) -- who trains with Easter -- will make his first defense against England’s Ashley Theophane (39-6-1, 11 KOs).

  • Manuel “Tino” Avila (19-0, 8 KOs) is moving up to featherweight to take on Rene Alvarado (23-6, 16 KOs) in the scheduled 10-round main event of Golden Boy’s “LA Fight Club” series on April 1 (Estrella TV, 10 p.m. ET) at the Belasco Theater in downtown Los Angeles. "Manuel Avila is one of Golden Boy's top fighters and rising stars to watch so his move up to featherweight on April 1will be an exciting event to see," Golden Boy CEO Oscar De La Hoya said.
