Oscar Collazo, the undefeated WBA and WBO minimumweight champion, will step into a high-stakes challenge on October 10, 2026. He’s set to face unified WBA and WBC flyweight champion Ricardo Sandoval in what many are calling a significant gamble. This pivotal boxing match will unfold at the Wintrust Arena in Chicago, Illinois.
The highly anticipated bout serves as the co-feature to the Floyd Schofield versus Lucas Bahdi card. Collazo, a 29-year-old Puerto Rican southpaw, aims to capture two world titles in a division two weight classes above his current reign, bypassing the junior flyweight division entirely. Sandoval, 27, an American boxer with Mexican heritage, will be making his first defense of these specific unified flyweight belts.
Oscar Collazo Ricardo Sandoval’s flyweight leap
Oscar Collazo, known as “El Pupilo,” brings an unblemished record of 15 wins, 0 losses, and 0 draws, with an impressive 12 knockouts, into this challenging encounter. He’s demonstrated dominant power at 105 pounds, stopping 4 of his last 5 opponents and accumulating 86 rounds of professional experience.
The move up to the 112-pound flyweight division represents a seven-pound jump for Collazo, nearly seven percent of his former weight limit. It’s an aggressive strategy that foregoes a gradual ascent through the 108-pound division, highlighting Collazo’s confidence in his ability to compete immediately at the elite level.
Trial run against Neider Valdez
Collazo had a brief taste of the flyweight division in his last outing on June 20, 2026, where he stopped Neider Valdez in the second round. While a convincing win, Valdez was a late replacement, offering limited insight into how Collazo’s power and chin would hold up against a top-tier, natural flyweight like Sandoval.
Valdez came in at 111.2 lbs, with Collazo at 110.6 lbs, for their 112-pound contest.
This single, short fight provided minimal evidence for Collazo’s long-term sustainability in the division. The true test of his pressure, punching power, stamina, and punch resistance against a fighter of Sandoval’s caliber remains to be seen. Golden Boy Promotions, a co-promoter of this card, has a history of backing fighters willing to take such risks.
Boxing history is filled with debates about legendary matchups and bold career moves.
Ricardo Sandoval’s championship reign
Ricardo Sandoval earned his WBA and WBC flyweight titles in July 2025 by traveling to Japan and defeating the highly regarded Kenshiro Teraji via a split decision. That grueling contest showcased Sandoval’s resilience and high work rate, particularly his ability to recover from a fifth-round knockdown and outwork Teraji in the later rounds.
At 5-foot-6, Sandoval holds a considerable four-inch height advantage over the 5-foot-2 Collazo. This physical difference, coupled with his proven experience against top opposition, positions him as a formidable champion. He’s shown he can maintain a high output and absorb punishment over 12 rounds.
The Teraji test and Sandoval’s grit
Sandoval’s performance against Teraji highlighted his ability to adapt and overcome adversity. Getting dropped in the fifth round but then fighting effectively enough to secure the titles speaks volumes about his mental toughness and physical conditioning. This demonstrated resilience will be a critical factor against Collazo’s potent power.
Collazo, while powerful at minimumweight, faces a different challenge in hurting an established flyweight like Sandoval. Failing to earn Sandoval’s respect early could force Collazo to match the champion’s relentless activity deep into the fight, a territory where Sandoval has already proven his mettle.
Many title defenses often boil down to such moments of grit and sustained effort. Such high-stakes championship bouts demand exceptional resilience from fighters.
Clashing styles: precision versus pressure
The fight between Collazo and Sandoval promises a compelling clash of styles. Collazo relies on precise timing, fluid lateral movement, and accurate body combinations to break down his opponents. He aims to land with enough force to disrupt his adversary’s rhythm and reduce their activity.
Conversely, Sandoval is known for his relentless pressure and consistent output. He seeks to overwhelm opponents with volume and a high pace. For Collazo to succeed, he must penetrate Sandoval’s defenses and land impactful shots that slow the champion down; otherwise, he risks being outworked over the championship rounds.
Southpaw advantage and counter dangers
Collazo’s southpaw stance offers a strategic advantage, allowing his rear left hand to target Sandoval’s body from an acute angle. However, delivering these shots requires him to cross the taller champion’s punching range, opening him up to counters. Sandoval’s straight right hand and uppercut will be readily available whenever Collazo dips or steps in, making entry a hazardous proposition.
The success of Collazo’s body assault will largely hinge on his ability to reach his target without absorbing significant damage in return. This intricate dance of offense and defense will dictate much of the fight’s early pace. If Collazo can’t effectively neutralize Sandoval’s aggression, he could find himself in a war of attrition.
Implications for Puerto Rican boxing history
For Oscar Collazo, this fight transcends personal ambition; it carries the weight of national pride. “Sandoval is a challenge that motivates me and my team. I was looking to make history and prove that there are no limits when you know what you’re capable of doing,” Collazo said. “This isn’t just for me.
This is for Puerto Rico and to raise the level of Puerto Rican boxing.”
Winning on October 10 would make Collazo a simultaneous two-division champion, holding belts at both minimumweight and flyweight. This achievement would solidify his place among Puerto Rico’s boxing greats and further elevate the island’s rich boxing heritage. It’s a strategic career move, certainly, but one steeped in tradition and legacy.
A path to multi-division stardom
Achieving two-division champion status would be a significant milestone, distinguishing Collazo from many other successful champions who opt for more conservative weight-class transitions. This aggressive pursuit of greatness could fast-track his path to becoming a pound-for-pound contender. His undefeated record and high knockout ratio already mark him as a fighter to watch.
Such a bold move also tests the conventional wisdom of progression in boxing, where fighters typically move up one weight class at a time. Collazo is deliberately taking a shortcut, betting on his innate talent and power to overcome the size and experience disadvantages. It’s a calculated risk with potentially immense rewards.
