ONE Fight Night 46: Hemetsberger vs. Diachkova took place on August 15, 2026 at Lumpinee Stadium, Bangkok. This source-led report turns 8 active official-source bout rows into a readable result inventory, including 1 championship-classified result. Every named winner, method, round and time below comes from the retained promotion record. When a field is absent, the report leaves it absent instead of completing the story from assumption.
The retained title result records Stella Hemetsberger over Natalia Diachkova by third-round knockout. Nico Carrillo and Marcos Aurelio also won by knockout, while Viet Anh Do recorded a third-round TKO; the other four outcomes were decisions.

What the retained pattern shows
Across 8 results, 4 are classified here as decisions and 4 as stoppages by the stored method wording. Every retained method falls into one of those two broad descriptive buckets. These totals are descriptive navigation aids. They do not measure entertainment value, competitiveness, judging quality or the technical merit of a performance, and they do not change the exact method text shown beside each fight.
Because this was a mixed-rules event, the result inventory is more useful when the discipline stays attached to every matchup. A knockout in kickboxing, a stoppage in MMA and a decision in submission grappling are retained as different source facts.
Sources, freshness and limitations
The local source row was last observed on August 29, 2026. Primary evidence: ONE Championship official event or results page. The complete retained card is available on the Fights Now event record. Verification here means the result fields match the retained official-source record; it is not a claim that promotional commentary is independent analysis. Corrections, overturned decisions and later source changes should be handled through the normal correction workflow. No featured image is attached because this batch has not performed a separate image-rights review.
This report is intentionally narrower than a conventional recap. The local inventory does not contain a complete independent account of momentum, tactics, injuries, crowd response or disputed moments, so none of those are invented. It also avoids presenting a source's marketing language as Fights Now's conclusion. Readers get a durable result index, direct access to the promotion source and a clear boundary around what the retained evidence can and cannot establish.
