Early Life and Background
Waldo Cortes-Acosta was born and raised in the Barahona region of the Dominican Republic. Before discovering combat sports, he was a baseball player and had competed professionally in the sport in his home country. His athletic foundation in baseball gave him strong hand-eye coordination and a competitive mindset that would later serve him in fighting.
He relocated to the United States to continue his baseball career, but eventually transitioned away from the sport. At the age of 24, Cortes-Acosta began training in both boxing and mixed martial arts, channeling his athletic background into a new discipline. He settled in Phoenix, Arizona, where he continues to live and train, and he joined the Ultimate Kombat Training Center as his primary gym.

Early in his development, he trained at the renowned Tristar Gym in Montreal, working alongside former UFC welterweight champion Georges St-Pierre. That high-level training environment helped him sharpen his striking and conditioning.
On November 12, 2021, he faced Muhammed DeReese at Bellator 271, winning the bout by unanimous decision and continuing his rise through the heavyweight ranks. Shortly afterward, on April 15, 2022, he captured the Legacy Fighting Alliance (LFA) Heavyweight Championship by stopping Thomas Petersen via third-round TKO at LFA 129.
