Oscar Collazo vs. Jesus Haro Keys to Victory: Breaking down tactics of each fighter

Tonight the undefeated Puerto Rican sensation will aim to defend his unified WBO/WBA strawweight world titles against American fighter Jesus Haro at the Honda Center in Anaheim, California, and live on DAZN. The bout will serve as the co-main event to the Arnold Barboza Jr. vs. Kenneth Sims Jr. headliner.

Collazo (13-0, 10 KOs) has won three straight fights by stoppage including his seventh-round knockout of Jayson Vayson in September and the fifth-round drubbing of Edwin Cano last March. He faces Haro (13-3, 2 KOs) who produced a knockout win in his sole ring appearance of 2025.

Will Collazo dazzle yet again in another shining performance highlighting boxing’s minimumweight star power? Or will Haro shock him with an upset? DAZN News analyzes the Keys to Victory for both men.

Oscar Collazo’s Keys to Victory

Beat Haro to the punch

Oscar Collazo setting the tone by beating his opponents to the punch is part of the reason why he is an undefeated unified strawweight world champion.

Beating Jesus Haro to the punch with the jab, timed counters or a bursts of blows will immediately let the challenger know the champ is dictating the terms of this bout.

Dig to the body with the left hand

Watch Collazo in action and the Puerto Rican sensation makes hard deposits to the body consistently toward pointed results.

These shots, especially with the left hands, debilitate his opponents and leave them ripe for something more significant to land upstairs.

Unleash the stab jab-hook combo

In a flash, Collazo is able to stab jab to the body and unleash a hook as a devastating combination that he should definitely look to detonate against an unsuspecting Haro who does not possess great speed.

Not only can this combo alter the fight, it can end it.

Make deposits to Collazo’s body

Jayson Vayson had some success targeting and landing shots to Oscar Collazo’s body.

Jesus Haro should take note and hone in on the unified strawweight champ’s midsection as well with some crunching offerings. It could be a way to sap Collazo’s hand speed and force him to lower his arms just enough for Haro to land something heavier upstairs.

Let hands go with measured gambles

To stand a chance against Collazo, Haro must crank up his volume and let his hands go, but with measured gambles.

This means upping his output, but making sure to not get erratic because Collazo is a skilled counterpuncher who can dramatically turn tides when opponents overzealously make mistakes.

Do not allow Collazo to pick his shots.

Considering Collazo fights well in bursts, picking his spots to pounce effectively, Haro might want to fight fire with fire in the form of his own pressure.

Standing up to Collazo's pointed force with pressure of his own is a must for the challenger to have any chance.
