Melissa Mullins vs Daria Zhelezniakova Fight Breakdown

Introduction

The highly anticipated Women’s Bantamweight clash between Melissa Mullins and Daria Zhelezniakova takes center stage on Saturday, June 21, 2025, as part of the preliminary card for UFC Fight Night: Hill vs Rountree Jr. The action kicks off at 4:00 PM UTC inside the illustrious Baku Crystal Hall in Baku, Azerbaijan, where fight fans from around the globe will tune in to witness two dynamic fighters collide at 135 pounds.

On paper, the betting markets have made their stance crystal clear: Melissa Mullins, the #15-ranked Women’s Bantamweight from England, enters as the favorite with odds hovering around -250. A powerful striker with a professional record of 7–1–0, Mullins has demonstrated finishing prowess—boasting 4 knockouts and an impressive 3 first-round stoppages—and carries into this bout a blend of precision striking (56% significant strike accuracy) and robust takedown defense (86%). She’ll be looking to extend her winning streak after her October 2023 UFC debut victory over Irina Alekseeva and a memorable second-round KO of Klaudia Syguła in November 2024.

Meanwhile, standing across the Octagon is Russia’s rising star Daria Zhelezniakova, the underdog at +195 to +211, who owns a 9–2–0 ledger and is no stranger to front-foot pressure. At 29 years old, Zhelezniakova blends striking aggression (100% takedown accuracy in her limited grappling forays) with a sturdy takedown defense (50%). After a unanimous decision win over Montserrat Rendon in March 2024, she faced a setback via first-round submission to Ailin Perez in September but has since been training to tighten her defensive grappling and sharpen her counter-striking.

What’s at Stake

  • For Melissa Mullins: A win cements her status among the division’s elite, pushing her closer to top-10 contention and potentially earning a spot on the main card in future events.
  • For Daria Zhelezniakova: An upset victory would catapult her up the rankings, showcase her evolution as a well-rounded threat, and prove that she can overcome seasoned foes on the international stage.

  2. Loss – KO/TKO vs. Nora Cornolle (Apr. 6, 2024) – 2nd round, 3:06
  3. Win – Decision (Unanimous) vs. Irina Alekseeva (Oct. 14, 2023) – 3 rounds

These results illustrate her ability to both go the distance and finish fights early, though the loss to Cornolle exposed vulnerabilities in her defensive striking under pressure.

  • Takedown Offense (38%) – Below division average, suggesting limited wrestling versatility if her striking is neutralized.

Strengths:

  • Takedown Accuracy (100%) – Perfect in her limited shoots, adding a dangerous dimension to her stand-up assault.
  • Significant Strike Defense (80%) – Exceptional at avoiding big shots, making her a tough target on the feet.
  • Power Striking – 5 KO wins attest to her ability to change the fight with one blow.

Weaknesses:

  • Submission Defense – The loss by arm-triangle choke to Perez exposes gaps in her grappling defense.
  • Striking Accuracy (38%) – Below par, indicating her aggression can lead to wasted energy and missed opportunities.
  • Takedown Defense (50%) – Vulnerable to wrestlers who can neutralize her striking and drag her into deep grappling exchanges.
