Beginning of Boxing Career

Despite his late start, Martinez quickly made a name for himself in Argentina’s amateur circuit, winning multiple regional titles.
His transition to professional boxing came in 1997, but his early career was far from glamorous. Fighting in small venues, Martinez faced financial hardships, often taking fights on short notice just to survive. His big break came when he moved to Spain, where he gained recognition before finally making his way to the United States, the mecca of boxing.
Professional Boxing Career

Martinez’s early years in the pro ranks were a mix of struggles and perseverance. He built a solid record in Argentina and Europe before finally getting noticed in the U.S. His technical skills and unorthodox style caught the attention of boxing promoters, leading to bigger fights.
One of his breakthrough moments came in 2009 when he faced Alex Bunema, dominating the fight and announcing himself as a serious contender. This victory set the stage for his legendary bouts against Kelly Pavlik, Paul Williams, and Julio César Chávez Jr.
Major Achievements and Championships
Martinez’s career reached its peak when he defeated Kelly Pavlik in 2010 to claim the WBC Middleweight title. This victory solidified his place among boxing’s elite.
One of his most iconic performances was against Paul Williams in their 2010 rematch, where Martinez delivered a devastating second-round knockout, a punch still celebrated as one of the best in boxing history.
In 2012, he faced Julio César Chávez Jr. in a highly anticipated bout. Despite being knocked down in the final round, Martinez won by unanimous decision, further cementing his legacy. That same year, he was named Ring Magazine Fighter of the Year.
Fighting Style and Strengths

Martinez was known for his southpaw stance, lightning-fast footwork, and counterpunching ability. Unlike traditional brawlers, he relied on movement, angles, and precision punching to outsmart opponents.
His defensive skills were exceptional—he could slip punches effortlessly and retaliate with sharp combinations. Fighters struggled to cut off the ring against him because of his elusive lateral movement.
Age and Physical Appearance
Standing at 5’10”, Martinez had a lean, athletic physique that allowed him to maintain speed and agility even as he aged. Unlike many boxers who bulk up, Martinez stayed slim yet powerful, relying on technique over brute strength.
Despite his graceful aging, the wear and tear of boxing began to show. By his late 30s, knee injuries slowed him down, affecting his signature movement.
Challenges and Injuries
Martinez’s career wasn’t without setbacks. His first fight with Paul Williams in 2009 ended in a controversial majority decision loss, a result many fans and analysts disputed.
His knee problems became a major issue, requiring multiple surgeries. These injuries were evident in his 2014 fight against Miguel Cotto, where he was knocked down three times before losing by TKO. This marked the beginning of his decline.
Retirement and Comebacks
After the Cotto loss, Martinez retired in 2014 due to persistent knee issues. However, in 2020, he made a brief comeback, defeating José Miguel Fandiño in Spain. Despite the win, he confirmed his permanent retirement shortly after, closing the chapter on an illustrious career.
Personal Life and Relationships
Martinez has always been a private individual, rarely sharing details about his personal relationships. He has mentioned his mother’s influence on his career, crediting her for his work ethic.
Unlike many celebrities, Martinez has no confirmed spouse or children, keeping his personal life away from the spotlight.
Philanthropy and Off-Ring Activities
