The Shocking 2019 Upset Against Andy Ruiz Jr.

One of the most dramatic chapters unfolded on June 1, 2019, at Madison Square Garden in New York. Anthony Joshua entered the ring as the undefeated unified heavyweight champion with a 22-0 record and 21 knockouts. He was making his highly anticipated United States debut against Andy Ruiz Jr., a late replacement after the original opponent failed a drug test. Joshua stood as a massive favorite, with odds often reaching minus 2500 or higher, implying that bettors needed to risk significant sums for modest returns on the Briton. Ruiz, carrying a 32-1 record but lacking the same star power or physical imposing presence, opened as a substantial underdog around plus 1100 to plus 2000 depending on the timing.

The fight itself turned chaotic almost immediately. Joshua dropped Ruiz in the third round, appearing to seize control. Yet Ruiz responded with remarkable resilience and hand speed. In the seventh round, he unleashed a series of powerful combinations that sent Joshua to the canvas multiple times. The referee stopped the bout, awarding Ruiz a seventh-round technical knockout and the WBA, IBF, WBO, and IBO heavyweight titles. This result ranked among the biggest heavyweight upsets since Buster Douglas defeated Mike Tyson in 1990.

Bettors who placed money on Ruiz at plus-money odds celebrated major payouts. Instances emerged where bets on the Mexican-American fighter at around 11-to-1 delivered strong returns, turning modest stakes into significant wins for those who spotted the value in the underdog. The loss exposed vulnerabilities in Joshua’s style against shorter, quicker opponents willing to exchange inside, and it sent shockwaves through the boxing world while enriching savvy punters who defied the heavy favoritism.

Redemption in the Ruiz Jr. Rematch

Six months later, on December 7, 2019, in Diriyah, Saudi Arabia, the two clashed again in a highly anticipated rematch. Joshua adjusted his approach dramatically, fighting from the outside with superior jab work and movement to neutralize Ruiz’s aggression. He controlled the distance effectively over 12 rounds and secured a unanimous decision victory to reclaim the titles. While Joshua was again the favorite, the rematch odds reflected greater caution following the first encounter, offering less extreme lines than the initial bout. Punters who backed Joshua to regain the belts through a more measured performance saw solid returns compared to the explosive payouts from the New York upset. The fight demonstrated Joshua’s adaptability and professional resilience under pressure.

Masterclass Defeat to Oleksandr Usyk in 2021

Another significant moment came in Joshua’s encounters with Oleksandr Usyk. In their first meeting on September 25, 2021, at Tottenham Hotspur Stadium in London, Joshua defended his titles as a clear favorite around minus 250 to minus 300. Usyk, the former undisputed cruiserweight champion transitioning to heavyweight, entered as an underdog at roughly plus 225. Many expected Joshua’s size and power to overwhelm the smaller, more technical Ukrainian. Instead, Usyk employed masterful footwork, angles, and ring generalship to outbox Joshua over 12 rounds, winning by unanimous decision with scores around 117-112. He claimed the WBA, IBF, WBO, and IBO belts in a masterclass that highlighted technical superiority over raw power. Bettors who wagered on Usyk at plus odds enjoyed strong payouts, as the result represented another notable upset in Joshua’s career and underscored the unpredictability of heavyweight boxing when styles clash.

Close Rematch with Usyk in 2022

The rematch took place on August 20, 2022, in Jeddah, Saudi Arabia. Joshua entered motivated to reclaim his titles, but Usyk remained the favorite at approximately minus 200, with Joshua available around plus 170. The bout proved competitive yet again, with both fighters exchanging momentum across 12 rounds. Usyk ultimately prevailed via split decision in a closely contested affair, retaining his belts. Scores reflected the tightness of the contest, but Usyk’s consistency and ability to land cleaner shots in key moments secured the victory. While payouts for backers of Usyk were more moderate due to his favoritism in the second fight, the series as a whole rewarded those who recognized the cruiserweight champion’s elite skill set against a larger opponent. Joshua’s losses to Usyk marked a turning point, prompting reflections on his evolution as a fighter.

Dominant Knockout Victory Over Francis Ngannou

In March 2024, Joshua faced former UFC heavyweight champion Francis Ngannou in Riyadh. Ngannou had stunned the boxing world months earlier by nearly defeating Tyson Fury in his professional debut. Joshua entered as a solid favorite around minus 300 to minus 350, while Ngannou sat as an underdog near plus 240 to plus 275. Expectations leaned toward Joshua using his boxing skills to outpoint or stop the powerful but relatively inexperienced striker. The fight ended abruptly in the second round when Joshua dropped Ngannou early and finished him with a devastating right hand for a knockout. Backers of Joshua on the moneyline collected straightforward returns, and those who wagered on an early stoppage or knockout in the second round enjoyed enhanced payouts. This dominant performance helped restore some confidence in Joshua’s power after previous setbacks.

Unification Win Against Joseph Parker

Joshua’s bout against Joseph Parker in 2018 provided a contrast in a more predictable outcome. On March 31 in Cardiff, Wales, Joshua was a heavy favorite around minus 600 to minus 1200 against the WBO champion Parker. The contest went the full 12 rounds, with Joshua winning by unanimous decision in scores such as 118-110. It marked the first time Joshua went the distance in a professional fight up to that point. Bettors favoring the favorite saw consistent returns given the lopsided odds, rewarding faith in Joshua’s superiority at that stage of his career.

Throughout his journey, Joshua has faced elite competition that tested every aspect of his game. The 2019 Ruiz upset stands as the pinnacle of unexpected payouts, where underdog backers turned modest investments into significant wins amid one of modern boxing’s greatest surprises. Subsequent clashes with Usyk further demonstrated the sport’s capacity for technical mastery to overcome physical advantages, delivering value to those who analyzed stylistic matchups. Wins against Parker and Ngannou reaffirmed Joshua’s place among the division’s top talents when conditions aligned.

The heavyweight division’s volatility ensures that Joshua’s future bouts will continue attracting attention from British sports enthusiasts. Each contest adds layers to his legacy, whether through redemption arcs or further tests against dangerous opponents. For fans reflecting on past results, the largest betting wins tied to his fights often stemmed from embracing the possibility of chaos in a sport where one punch or strategic adjustment can rewrite expectations entirely. Joshua’s career serves as a compelling reminder of boxing’s enduring appeal in the United Kingdom, where passion for the sweet science pairs naturally with the excitement of major events.
