Fighter Breakdown: Errol Spence Jr.

Well rested or rusty from inactivity? Those are the questions facing Spence Jr. ahead of this fight. He hasn’t fought in three years when he was humbled and sent to the canvas three times in a crushing loss to Terence Crawford in a unification bout. There is no questioning his skill as a boxer. At his peak Spence Jr. was No. 4 in the pound-for-pound boxing rankings.

Strengths and Path to Victory

• Known throughout his career as a slow starter, Spence Jr. must withstand the early rounds where Tszyu will certainly aim to leave a mark.
• Spence Jr. relies on conditioning and his ring experience to take control of the later rounds.
• A powerful puncher with 22 of his 28 career victories by KO.

Concerns and Betting Risks

• His lengthy three-year hiatus is one obstacle that training and sparring can’t overcome.
• Time away from the ring and the damage inflicted on him by Crawford in his last fight are things Spence Jr. must overcome.

Fighter Breakdown: Tim Tszyu

While he’s been more active inside the ring over the last three years, Tszyu hasn’t exactly enjoyed a lot of success. After starting his professional career with 24 consecutive victories he endured a spell of three losses in a four-fight span. He has won his last two bouts against lesser foes. He is the more active fighter, but boxing predictions shouldn’t give him a win.

Strengths and Path to Victory

• With six bouts under his belt since Spence Jr. last entered the ring, Tszyu will have an edge in that area.
• A physically imposing fighter at his weight, Tszyu will attempt to engage Spence Jr. in the middle ring where he can impose his strength.
• Five years his opponent’s junior, Tszyu will use that advantage to exploit Spence Jr. and his time away from the ring to force an early stoppage.

Concerns and Betting Risks

• The recent stretch of three losses in four matches has some wondering if Tszyu has started a decline.
• If Tszyu doesn’t take advantage of his opponents inactivity and end the fight early his chances of winning decrease.
• The move up to middleweight can take a toll on Tszyu, who’s fought at the lower classifications his entire career.

Boxing Rankings and Fight Implications

Both fighters are former world champions but neither is currently listed in the boxing rankings. Spence Jr. was a three-time world champion and at the top of his game reached No. 4 in the world in pound-for-pound boxing rankings. Spence hasn’t fought in three years and Tszyu is moving up a weight class.

What a Win Means for Errol Spence Jr.

• This is likely the last chance for Spence Jr. to reestablish himself as an elite pound-for-pound fighter.
• He could have chosen a lesser opponent for his comeback instead he’s going after a former world champion to show he’s serious about his return.

What a Win Means for Tim Tszyu

• After his first career setbacks, Tszyu rebounded with a pair of wins against overmatched opponents. Tszyu is attempting to crack the middleweight division as a contender.
• Fighting bigger, stronger opponents, Tszyu has to change his strategy and become more defensive with improved head and upper body movement.

Rival Boxing Storylines

There is a budding rivalry between the two fighters fostered outside the ring. Spence Jr. has repeatedly refused to shake his opponent’s hand at promotional events. Tszyu countered by mocking Spence’s intensity, claiming Spence Jr. looks rattled and nervous due to the pressure of traveling to Australia for the fight.

Careers are also on the line making this rival boxing match more than a spectacle. Spence Jr. is proving he’s not washed up with his career at the elite level done with a loss. Recent losses have Tszyu battling his confidence with a setback to an inactive Spence Jr. labeling him as a fighter who can’t win the big one.

Is This a True Rival Boxing Matchup?

• Most will say this fight certainly is a highly personal boxing rivalry.
• The bad blood between Spence Jr. and Tszyu has built up with years of public disrespect and severe hostility the week leading up to the fight.
• Ultimately this is a rivalry due to the years-long grudge and the career stakes on the line.

Boxing Predictions for Spence Jr. vs. Tszyu

There are valid points to argue for each side to win this fight, which is likely why the boxing betting odds are so tight. There is something to be said about an elite fighter who elected to take several years away from the sport to confirm his life choices. Spence Jr. is better built for the middleweight class, has a size and reach advantage, and is my boxing prediction pick to win this fight.

Fight Script Prediction

• Fighting in his home country against an opponent coming off a three-year layoff, Tszyu will come out hard in the early rounds. He doesn’t end the fight and Spence Jr. gets more active in the middle rounds.
• Both fighters battle fatigue in the middle rounds with little in the way of devastating blows.
• One Spence Jr. gets into a rhythm, his superior athleticism and boxing IQ takes over keeping Tszyu from landing the knockout punch he desperately needs.

Official Prediction

• My boxing prediction has Spence Jr. winning the fight by split decision.
