"On April 27th, Buenos Aires, Argentina, plays host to a much-anticipated homecoming. Middleweight kingpin Sergio Martinez returns to his native country for the first time in 11 years. After claiming the middleweight crown three years ago, Martinez has been nothing short of dramatic.
"Seven months ago, he continued his streak with a thrilling victory over Mexico's then-undefeated Julio Cesar Chavez Jr. The gutsy performance helped cement the 38-year-old Martinez's place as one of the top pound-for-pound fighters in the world.
"Now Sergio Martinez will defend his championship against undefeated Englishman Martin Murray. Heavy-handed and with relentless pressure, the 30-year-old Murray looks to play spoiler in the biggest fight of his career.
"From the 50,000 seat Velez Sarsfield stadium, will the underdog pull off the upset, or can the 2010 Fighter of the Year put on another show in the long-awaited return to his hometown?
"Also that night, 6,000 miles northwest in Ontario, California, it's the return of Chris 'The Nightmare' Arreola. In a clash of heavyweights, he'll take on once-defeated Bermane Stiverne. It's a unique edition of World Championship Boxing."
