A few notes from around the boxing world:
• After lightweight contender Petr Petrov (37-4-2, 18 KOs), the 2014 Boxcino tournament champion, badly swelled the left eye of former world title challenger Marvin Quintero and won their brawl by sixth-round knockout last Friday night in Las Vegas, the Spain-based Russian pronounced himself ready to fight for a 135-pound world title.
"When we saw that his eye was closing, my corner was telling me to throw more right hands," said Petrov, who lost a junior welterweight title fight by fourth-round knockout to Marcos Maidana in 2011. "I now just want to fight any of the champions. I know I can beat them, and I want to become world champion."
Artie Pelullo of Banner Promotions, Petrov’s promoter, said he already has begun working on securing Petrov, 33, a shot at one of the belts.
• Featherweight contender Ronny Rios (25-1, 10 KOs), 26, of Santa Ana, California, will face Efrain Esquivias (17-4-1, 10 KOs), 32, of Gardena, California, on June 3 (Estrella TV) on Golden Boy's "LA Fight Club" card at the Belasco Theater in downtown Los Angeles, Golden Boy matchmaker Robert Diaz told ESPN.com.
Rios is coming off a 10-round decision win against former world-title challenger Jayson Velez in November on the Canelo Alvarez-Miguel Cotto HBO PPV undercard. Esquivias has lost two eight-round decisions in a row and has not fought since last May. In 2013, he knocked out former bantamweight and junior featherweight champion Rafael Marquez in the ninth round, sending him into retirement.
• Brooklyn, New York, heavyweight Jarrell "Big Baby" Miller (16-0-1, 14 KOs) will face Nick Guivas (12-3-2, 9 KOs), of Topeka, Kansas, on May 27 at the Seneca Niagara Resort & Casino in Niagara Falls, New York. The fight headlines promoter Greg Cohen's CBS Sports Net-televised card. In the 10-round lightweight co-feature, Filipino prospect Harmonito Dela Torre (17-0, 12 KOs) will make his American debut against Guillermo Sanchez (15-18-1, 6 KOs), of Buffalo, New York.
