Wilder took a step closer to the goal of seizing all the championship belts as he defeated his opponent on knockout in the seventh round.
Until then, Wilder looked to lose - but all it took to end the game was a devastating right. Ortiz managed to get up but the referee interrupted the match after looking into his eyes.
After the match, Wilder praised his opponent.
- He is one of the best in the world and that's why I gave him this chance, he says according to CBS Sports.
34-year-old "Bronze Bomber" Wilder began his career as an amateur boxer in 2005 and won the Olympic bronze in Beijing in 2008. Later that year he became a professional and in 2015 he won the WBC belt in heavyweight.
