Maciej Sulecki Bio
Maciej Sulecki, born 2 May 1989 in Warsaw, Poland, is a Polish professional boxer known by the nickname Striczu. Competing since 2010 across the light-middleweight, middleweight, and super-middleweight divisions, he has built a professional record of 33 wins and 4 losses over 37 total bouts, with 13 of his victories coming by knockout and the rest largely by decision. Standing 185 cm tall with a 173 cm reach and an orthodox stance, Sulecki gained worldwide attention in 2019 when he challenged for the WBO middleweight title. His career has spanned both Polish and American venues, pairing him with leading promoters and several top-tier opponents along the way.
Early Life and Background
Maciej Sulecki was born in Warsaw, Poland, and grew up in a country with a long and storied tradition of Olympic and professional boxing. From an early age, he was drawn to the sport, training in local gyms and developing the disciplined habits that would later define his career. Warsaw’s competitive amateur scene provided Sulecki with a steady stream of sparring partners and tournaments, allowing him to refine his natural frame into a classic middleweight build.
As a teenager, Sulecki rose through the Polish junior ranks, eventually earning a reputation as one of the country’s most promising young talents. He went on to compile a 110-30 amateur record, a tally that included three Polish Junior championships. Those formative years gave him the technical foundation and ring experience he would rely on once he turned professional in his early twenties.
Path to Professional Boxing
Following his successful amateur career, Sulecki made the transition to the professional ranks in June 2010, debuting in Kielce, Poland. He wasted little time in announcing himself, stopping Adam Gawlik by first-round knockout and signaling the aggressive intent that would mark his early years in the paid ranks. The early schedule was busy, with Sulecki taking on experienced opponents to build his craft.
In June 2012, he scored one of the most important early wins of his career, defeating former welterweight world champion Yuriy Nuzhnenko by unanimous decision. The victory showed that Sulecki could handle a seasoned, high-caliber fighter over a full ten rounds, a skill he would need as his competition grew tougher. By 2013, with 15 straight wins behind him, he was ready to contest national titles and a bigger stage.
Maciej Sulecki Career
Early Career (2010-2014)
Sulecki’s first major title opportunity came in November 2013, when he faced Lukasz Wawrzyczek for the vacant Republic of Poland middleweight title. He claimed that belt by unanimous decision, establishing himself as a leading domestic fighter. A few months later, in May 2014, he added the Polish International super-middleweight title to his résumé with a ten-round decision over Nicolas Dion of France.
Later in 2014, Sulecki took a significant step up in class against Grzegorz Proksa, a former European champion and WBA middleweight world title challenger. Fighting at the Krakow Arena, Sulecki absorbed an unorthodox early assault before turning the fight around, stopping Proksa in the seventh round with a right-hand counterpunch. The win announced him as a serious force in the European middleweight picture.
U.S. Debut and International Rise (2015-2017)
Following his win over Proksa, Sulecki aligned with American promoter Lou DiBella and influential manager Al Haymon, paving the way for his U.S. debut. In April 2015, he traveled to the UIC Pavilion in Chicago, where he knocked out Darryl Cunningham in the third round. He then stopped 40-year-old Jose Miguel Berrio in the first round at the Prudential Center, a performance that saw him added to Sherdog’s Top 10 middleweights list.
In 2016, Sulecki defeated previously unbeaten Hugo Centeno Jr. with a final-round knockout, his fifth straight stoppage and a sign of growing finishing power. He moved down to light-middleweight in 2017 and decisioned Jack Culcay in October of that year, a win that set up a defining matchup with former world middleweight champion Daniel Jacobs. Although he lost that bout by unanimous decision, the fight placed him firmly on the global stage and led to a WBO number-two ranking.
World Title Challenge (2018-2019)
Sulecki’s stock at middleweight earned him a mandatory shot at the WBO world title against Demetrius Andrade. Going into the fight as a heavy underdog, the Polish fighter was outboxed from start to finish, losing every round on the cards and suffering a knockdown along the way. The result was a clear defeat, but the performance confirmed his place among the elite middleweights of his era.
Super-Middleweight Move (2024)
In August 2024, Sulecki moved up to super-middleweight to face Diego Pacheco in Carson, California, with the WBC USA and WBO International super-middleweight titles on the line. The fight was halted in the sixth round when a left body hook put Sulecki on the canvas, ending the bout by knockout. The loss was a setback, but it also reflected his willingness to test himself against rising contenders in a new weight class.
Driving Style and Strengths
Sulecki fights from an orthodox stance, using his 185 cm frame and 173 cm reach to box at a measured distance. He is a composed decision fighter, with 20 of his 33 wins coming on the cards, though his résumé also features 13 knockouts, including several late-round stoppages. His partnership with promoters and managers on both sides of the Atlantic has helped him secure high-profile opportunities against top names.
Notable Events and Milestones
Key milestones include his unanimous decision over former world champion Yuriy Nuzhnenko in 2012, his Republic of Poland middleweight title win in 2013, and his 2014 seventh-round stoppage of Grzegorz Proksa. His U.S. debut in 2015, the unanimous decision win over Jack Culcay in 2017, and his 2019 WBO world title challenge against Demetrius Andrade all marked defining moments in his career.

2025 Season Performance
Heading into 2025, Maciej Sulecki is looking to rebound from his sixth-round knockout loss to Diego Pacheco in August 2024. The super-middleweight contest for the WBC USA and WBO International titles gave him valuable experience at the higher weight, even though the result went against him. With a 33-4 professional record behind him, he remains an experienced name capable of landing meaningful fights in both the middleweight and super-middleweight divisions.
Sulecki’s 2025 outlook will likely depend on how quickly he can return to top form and what opportunities his team can secure on the international calendar. His long association with promoter Lou DiBella and manager Al Haymon has historically given him access to high-profile matchups in the United States and Europe, a network that should help him find competitive bouts. A return to the middleweight ranks could also be on the table, where his earlier world-level experience at 160 pounds could open doors to regional or eliminator fights.
For Polish boxing fans, 2025 offers a chance to see whether the Warsaw native can finish his career on a high note, with potential title contention still within reach at 33 years of age. Whether he campaigns at middleweight or super-middleweight, Sulecki’s combination of size, orthodox fundamentals, and decision-making experience should keep him relevant in a packed global middleweight scene. His next steps will be closely watched as he aims to add to his already impressive résumé of 33 professional wins.
