A little of this and a little of that from the boxing world:
• As part of the lead-up to the Floyd Mayweather Jr.-Robert Guerrero welterweight title fight on May 4 (Showtime PPV) at the MGM Grand in Las Vegas, the documentary “30 Days In May” debuts on Wednesday night (Showtime, 10 ET/PT). The one-hour film chronicles the days between Mayweather’s May 5, 2012, win over Miguel Cotto and the June 1 start of a three-month jail term for domestic abuse at the Clark County Detention Center in Las Vegas. The film concludes on Aug. 3, Mayweather’s self-described “best day of my life,” when he was released early for good behavior after serving two months behind bars. The documentary features the only interviews Mayweather has conducted (so far) about his incarceration, which he calls a “life-changing experience.”
• Middleweight champ Sergio Martinez (50-2-2, 28 KOs) and challenger Martin Murray (25-0-1, 11 KOs) of England, who meet April 27 (HBO) in Buenos Aires, Argentina, Martinez’s home country, were both inside the limit of what they were allowed to weigh for their 30-day weight check. They were each 170 pounds a month before their 160-pound championship fight.
• "Friday Night Fights” fan favorite Delvin Rodriguez (27-6-3, 15 KOs) returns to the ESPN2 series on May 24 at the Mohegan Sun casino in Uncasville, Conn., where Connecticut resident Rodriguez is a good draw. He’ll face fellow former welterweight title challenger Freddy Hernandez (30-4, 20 KOs) in a scheduled 10-round junior middleweight bout.
• The epic Mike Alvarado-Brandon Rios rematch at Mandalay Bay in Las Vegas on Saturday night was another hit for HBO, which said that, according to Nielsen Media Research, it drew 1.2 million viewers for the live airing. That was a 45 percent increase in viewership from the first Rios-Alvarado fight, which was also a barn-burner, but on an undercard. Saturday’s undercard fight between unknown junior welterweight prospect Terrence Crawford and Breidis Prescott drew 845,000 viewers, according to the network.
• Promoter Don King, who won the purse bid for the third fight between cruiserweight titlist Marco Huck (35-2-1, 25 KOs) and Ola Afolabi (19-2-4, 9 KOs) despite not handling either fighter, told the camps that the fight would take place May 11 in Germany. However, King, who bid a surprising $1.5 million, still does not have a specific venue lined up or a television deal in place The fighters are both in training camp, but their handlers remain skeptical that the fight will come off. Without a TV deal, King would likely default on the bid.
