Wilder, known as 'The Bronze Bomber', came into the fight with a fearsome reputation. He'd gone 43 fights unbeaten, holding the WBC World Heavyweight title for five years. His power was legendary - 42 of his 43 wins came by knockout, with only one opponent making it to the final bell.
But things changed after his trilogy with Tyson Fury. The first fight ended in a draw, but Fury won the next two by knockout, taking Wilder's title. Wilder tried to bounce back, stopping Robert Helenius in the first round. Then came the Parker fight.
Parker upset the odds impressively. He nullified Wilder's famous right hand, even hurting the American at times. The judges saw it all Parker's way, giving him every round.
After the fight, Parker spoke to Boxing News about his cautious approach:
"I was very cautious in the beginning of the fight, because of what Wilder presents and how dangerous he is as a fighter – he can finish you off just like that in the blink of an eye. I was picking my moments, picking my shots. As the rounds progressed I was gaining more confidence in what I was doing."
Parker also acknowledged Wilder's power:
"Practice, practice, practice. Work, work, work. Listen, I had to be aware of it at all times. He did catch me a few times on the guard and, I'll tell you this, it's a very hard right hand. If it landed clean it would've been different, but today's my day."
Things got worse for Wilder in his next fight. Zhilei Zhang knocked him out in five rounds, adding another loss to his record.
Despite these setbacks, Wilder, now 39, says he'll keep fighting. He's shown interest in a bout with Francis Ngannou, the former UFC champ who recently lost to Anthony Joshua after a close fight with Tyson Fury in his boxing debut.
