Sergio Martínez vs. Matthew Macklin, billed as Get Your Irish Up, is a boxing middleweight bout for The Ring world title and universally recognized middleweight championship of the world.[2] The bout was held on March 17, 2012, at the Theater at Madison Square Garden in New York, New York, United States.[3]
The fight was televised live on HBO World Championship Boxing.[4]
During a press conference in his native Argentina on December 29, Martínez renounced his WBC "Diamond" belt and indicated he might pursue a relationship with Showtime over HBO, as he felt HBO mistreated him.
Martínez was forced to give up his WBC belt for fighting Sergei Dzinziruk in March on HBO, a bout Martínez won by an eighth-round KO. The WBC then elevated Sebastian Zbik to the status of full champion and mandated that Zbik face Julio Cesar Chavez Jr., who dethroned Zbik in June.
Martínez was rated No. 3 in THE RING's pound for pound list and was coming off an 11th-round knockout of Darren Barker in October.[5]
In his last fight in June, Macklin lost a controversial split-decision to RING No. 2-rated middleweight and WBA belt holder Felix Sturm, of Germany.
Sturm recently held on to his crown, yet again, with a split-draw against rated middleweight Martin Murray on Dec. 2.[6]
Martínez would struggle throughout the first half of the fight, with Macklin able which neutralized much of Sergio's offensive attack. Macklin would score a knockdown on Martínez in the seventh round. Martínez was able to turn the tide in the later rounds, finding his range with his left hand. After scoring two knockdowns in the 11th, Macklin's corner stopped the fight shortly before the 12th round.
Martínez would sign to face WBC titleholder Julio César Chávez Jr., despite Chávez's godfather Jose Sulaiman attempting to block the bout.[7]
