Junior featherweight titleholder Nonito Donaire was dominant in all four of his 2012 fights -- all world title bouts against quality opponents -- to earn fighter of the year honors. He hopes to kick off his 2013 candidacy by beating fellow titleholder Guillermo Rigondeaux in a unification fight.

They will meet April 13 in the main event of HBO's "World Championship Boxing" at Radio City Music Hall in New York City, promoter Top Rank announced Tuesday. A news conference is scheduled for Thursday in New York City.

"There's no question that fighting at Radio City Music Hall is like a coronation for the fighter of the year, fighting on that historic stage," Top Rank chairman Bob Arum told ESPN.com. "We couldn't get the Theater [at Madison Square Garden] so [MSG executive vice president] Joel Fisher said maybe he could get Radio City, because the Garden owns it. We said that was a great idea. It's expensive to do a fight there, but it's worth it.

"I think it's going to be a terrific fight. It's one I have wanted to see. These guys have been spouting off about each other for a long time and now it will be decided in the ring."

The fight will be just the second in the 82-year history of Radio City Music Hall. In January 2000, Roy Jones Jr. defended the light heavyweight world title there against David Telesco.

"I've heard so much about the place and how Roy fought there and Roy is one of the guys I look up to, so I am very excited about fighting there," Donaire told ESPN.com.
