Gabriela Fundora added another defence to her undisputed flyweight title run and extended her knockout streak with a methodical sixth-round stoppage of Viviana Ruiz on Saturday night at the Honda Centre in Anaheim, California.
Fundora, now 18-0 (10 KOs), retained her Ring Magazine, IBF, WBA, WBC and WBO flyweight belts on the Arnold Barboza–Kenneth Sims undercard, halting Ruiz at 1:25 of the sixth round in a bout streamed on DAZN. The victory marked her sixth stoppage in seven fights since lifting the unified 112lb crown in 2023.
Ruiz entered as the WBA interim title-holder and a first-time challenger at this level, bringing a 10-3 (5 KOs) record and a late-blooming career story. The 43-year-old, who worked as an engineer before turning professional five years ago, came forward from the opening bell and tried to close the distance against the taller champion.
Fundora, a 5ft 9in southpaw from Coachella Valley, used her seven-inch height and reach advantage from the outset. She relied on a steady right jab and straight left hands behind it, opening the fight at a measured pace. Ruiz tried to capitalise on Fundora’s cautious start by launching overhand rights and stepping inside, and she did connect cleanly with a right hand in the second round. Fundora absorbed the shot and resumed her jab.
By the third round, the pattern was clear. Ruiz pressed, but often had to reach with her punches. Fundora’s jab kept her at bay and created lanes for straight lefts and short combinations. The champion’s output increased while Ruiz’s success remained sporadic. Visible swelling began to form under Ruiz’s right eye as the contest moved into the middle rounds.
CompuBox-style statistics reflected the flow of the bout. Fundora outlanded Ruiz 102-22 in total punches across the six rounds, controlling the exchanges and limiting Ruiz’s opportunities to land in combination. Most of Ruiz’s offence came in single shots, which Fundora either blocked, slipped or took without any evident effect.
The first breakthrough came late in the fourth round. Fundora stepped in behind the jab and let go with a three-punch combination that ended with a straight left, sending Ruiz to the canvas in the closing seconds of the round. Ruiz beat the count and the bell sounded before Fundora could follow up.
Sensing the shift, Fundora increased the pressure in the fifth. She backed Ruiz up more consistently, firing combinations to head and body. Ruiz remained upright but took a growing number of clean punches, finishing the round under sustained fire as Fundora closed strongly.
The end came early in the sixth. Fundora drove Ruiz into a corner and let her hands go with a series of straight lefts and rights. Ruiz, still trying to fire back but unable to mount a meaningful response, absorbed a string of unanswered punches. Referee Ray Corona stepped in at 1:25 of the round, waving off the contest and preventing further damage.
The result further strengthens Fundora’s position near the top of the women’s pound-for-pound lists. With her flyweight reign gathering momentum and her stoppage rate rising, she has spoken about a future move down to light-flyweight at 108lbs. For now, though, she remains in control of the flyweight division, with her latest defence reinforcing her status as the division’s dominant champion.
