Daniel Blancas vs Sergio Jimenez: Undefeated Prospect Hits San Diego
Daniel Blancas enters September 19 undefeated at 15-0, but the sound of his punches during fight week may have already made him one of the most difficult fighters inside Eddy Reynoso’s gym to ignore.

Sometimes You Hear a Fighter Before You Notice Him
There are fighters whose presence comes from the crowd around them, and there are fighters whose work creates its own attention.
Daniel Blancas belonged to the second category during the PBC San Diego media workout.
As conversations continued around the gym and cameras moved between fighters, the impact of Blancas’ punches continued cutting through the room.
That sound is difficult to translate into a still image, but it provides an introduction to an undefeated super middleweight who is quietly moving into increasingly significant fights.
Blancas Is 15-0 — But Sergio Jimenez Brings Real Power
Blancas enters September 19 at 15-0 with seven knockouts.
Across from him is Sergio Jimenez at 17-1-1 with 15 knockouts.
That knockout total changes the equation.
Jimenez is not simply arriving with experience. His record suggests a fighter capable of changing a contest quickly, meaning Blancas has to manage both the technical and physical questions presented by the matchup.
Ten Rounds Changed the Development Curve
Blancas’ most recent fight provided a different type of experience.
In May 2026, he went 10 rounds for the first time and earned a wide unanimous decision over Raul Salomon.
For developing fighters, those rounds can matter as much as knockouts.
They reveal how a fighter manages pace, fatigue and adjustments when an opponent does not disappear early.
Now Blancas returns against a fighter whose record carries considerably more finishing power.
Hear Daniel Blancas’ Punches
The media workout told part of the Blancas story before anyone needed to explain it. Watch—and listen—to the undefeated super middleweight work.
Headphones recommended.
A Chance to Move From Prospect to Name Recognition
The super middleweight division is full of recognizable fighters, but every established name began with nights like this.
A major card. A dangerous opponent. A growing audience.
Blancas does not need to solve the entire division on September 19.
He needs to show that the fighter people heard inside the gym can create the same reaction once the fight becomes real.
