Early Career
Kelvin Gastelum started his journey in combat sports as a wrestler. He was a state champion at Cibola High School in Yuma, Arizona, and later wrestled at North Idaho College. However, his path shifted quickly towards Mixed Martial Arts.
He made his professional debut in 2010 and won his first five fights, finishing every single opponent.
His big break came in 2013 when he joined season 17 of The Ultimate Fighter (TUF). He was the last pick for Team Sonnen, but he shocked everyone by defeating highly-touted prospects like Bubba McDaniel and Josh Samman.
In the finale, he faced the terrifying knockout artist Uriah Hall. Despite being a massive underdog, Gastelum used his wrestling and pressure to win a split decision, becoming the youngest TUF winner in history and securing a UFC contract.
Professional Career
Gastelum’s UFC career has been a rollercoaster of high-level performances and struggles with weight management. He started at welterweight but frequently missed the weight limit, forcing a permanent move to middleweight.
At 185 pounds, he proved he was elite by knocking out veterans like Tim Kennedy and Michael Bisping.
His career defined itself in 2019 when he fought Israel Adesanya for the interim middleweight title. The fight was an instant classic and was inducted into the UFC Hall of Fame’s Fight Wing in 2025.
Although he lost by decision, his stock rose immensely. Since then, he has faced the division’s best, including losses to Robert Whittaker and Jared Cannonier, but he bounced back in 2025 with a win over Dustin Stoltzfus.
