Ryan Gandra KOs Ozzy Diaz in R1 to extend win streak to 10

Ryan Gandra delivered another emphatic first-round finish, knocking out Ozzy Diaz at UFC 331 on September 19 to push his winning streak to ten consecutive victories.

Gandra, known by his nickname "Problema," improved to 11-1 in mixed martial arts and went a perfect 3-0 inside the Octagon, with all three UFC wins coming by first-round knockout. The 31-year-old orthodox striker stands six-foot-one with a 74-inch reach and has established himself as one of the more dangerous finishers on the roster, posting a remarkable 11.71 significant strikes landed per minute. He has not suffered a defeat since 2022, and six of his current streak have ended by knockout stoppage. The sequence that closed Saturday's contest was familiar: Gandra pressed Diaz toward the fence, unloaded a combination, scored a knockdown, and the referee waved it off before Diaz could recover.

Diaz, 35, entered the contest at 10-4 overall and brought genuine physical advantages to the matchup. The orthodox heavyweight stands six-foot-four with a 79-inch reach — a 201-centimeter wingspan — and had shown the ability to generate output, averaging 6.44 significant strikes landed per minute across his career at a fifty-percent striking accuracy rate. Those advantages were not enough to weather Gandra's pressure on the night.

Why it matters

• Gandra's 3-0 UFC start with three first-round knockouts signals he could be approaching ranked territory in his division.
• A ten-fight win streak anchored by six knockout stoppages reinforces a dangerous finishing pattern that opponents have struggled to solve.
• Diaz drops to 10-4 and, at 35, faces added urgency to respond after back-to-back losses could threaten his roster standing.
