Fighting out of Accokeek, Md., Hurd has an unblemished professional record since turning pro in 2012. The 25-year-old opened up 2015 with a third-round stoppage of veteran Eric Mitchell and followed with a seventh-round stoppage of previously unbeaten Jeff Lentz in August. He stepped up in competition last November when he faced Frank Galarza in Las Vegas and was able to show off his considerable skill by stopping the previously unbeaten fighter in the sixth round of perhaps a career-best performance.

Representing Mexico, the 2012 Olympian Molina fights out of Norwalk, Calif., and is unbeaten in his brief professional career. The 26-year-old turned pro in 2013 and after winning a decision in his first bout, he went on to knock out six opponents in a row. His last bout came against fellow unbeaten Domonique Dolton and featured exciting back-and-forth action before the fight was ruled a majority draw.

The younger brother of undefeated Jose Benavidez, David has racked up a perfect 14 wins in 14 starts at just 19-years-old. Fighting out of Phoenix, Benavidez picked up four victories via stoppage in 2015 and kicked off his 2016 with a knockout of Kevin Cobbs in January. Most recently, he scored a second round knockout of Phillip Jackson Benson in April. The next challenge for Benavidez is the 33-year-old Ntetu, who won three times in 2015. Originally from the Democratic Republic of Congo, he fights out of Montreal and will be making his fifth appearance in the U.S. on June 25.

A popular Brooklyn fighter who competed in Barclays Center's first-ever professional female boxing match, Hardy has become a staple at the arena since. On June 25, she will be making her seventh appearance at Barclays Center. A little over two years after her pro debut, Hardy won an international title belt in the super bantamweight division in October 2014. In 2015, she defeated Noemi Bosques and Renata Domsodi twice. In her lone 2016 fight, she stopped Anna Donatella Hultin in the fourth round.

A two-time New York Golden Gloves champion, Kownacki had a big 2015, notching four victories including knockouts of Maurenzo Smith and Randy Easton. Born in Lomza, Poland, the 26-year-old now calls Brooklyn home. His 2016 campaign began in January at Barclays Center when he defeated Danny Kelly in front of a raucous Polish crowd.

Originally from New Orleans but fighting out of Houston, Prograis continues to work his way up the 140-pound rankings as he takes down veteran contenders. The 27-year-old looked sensational in his last outing as he scored a first round knockout over Mexico's Aaron Herrera. Already named on of ESPN's top prospects in 2015, he will look to cement his contender status in 2016.

Born in the Dominican Republic, Alonso moved to Spain at seven-years-old and would eventually represent the country at the 2012 Olympics. Now training in Brooklyn, the 25-year-old is undefeated since turning pro in 2014 while splitting time fighting in New York and Spain.  He is coming off a victory over Ricardo Maldonado in February.

Vargas began boxing at age eight and by by age 13 the New York Daily News dubbed him a "prodigy." Fighting out of New York, the 17-year-old Vargas recently signed to the Mayweather Promotions stable and will make his debut with his new promoter on June 25.
