Ruan Alvarenga completed a two-match sweep of Meyram Maquine at ONE Fight Night 46, earning a unanimous decision in the Brazilians’ featherweight submission grappling rematch. The victory at Lumpinee Stadium in Bangkok gave Alvarenga a successful ONE Championship debut and repeated the outcome of their first meeting.

What happened

Alvarenga and Maquine arrived at ONE Championship with an established rivalry after meeting in 2025. Alvarenga won that contest by referee’s decision, creating the backdrop for Saturday’s rematch and Maquine’s attempt to even the series.

The second meeting again went to the judges, but this time the result was unanimous. Alvarenga secured the decision to improve to 2-0 against Maquine and begin his ONE tenure with a victory in the featherweight submission grappling division.

Why it matters

Maquine entered the rematch as a two-time IBJJF world champion with a chance to avenge his previous loss. Alvarenga denied that bid and reinforced the result of their 2025 contest by defeating Maquine under the ONE Championship banner.

One close result can leave room for a rematch to settle the matchup. Alvarenga’s second victory, delivered by unanimous decision, gives him a clear sweep and strengthens his position as ONE considers future featherweight submission grappling bookings.

By the numbers

Alvarenga brought 20 professional victories into his ONE debut, with nine of those wins coming by submission. His two results against Maquine now include a referee’s decision in 2025 and a unanimous decision at ONE Fight Night 46.

Maquine entered ONE with considerably more professional experience, carrying 135 wins and 68 submissions into the event. That record, combined with his two IBJJF world championships, made Alvarenga’s repeat victory a significant opening result in the promotion.

What to watch next

Alvarenga’s next booking will offer the clearest indication of how ONE views his place in the featherweight submission grappling division. A winning promotional debut against a decorated and experienced opponent gives the organization a strong result to evaluate when selecting his next matchup.

For now, the immediate takeaway is decisive: Alvarenga has beaten Maquine under two different decision formats in consecutive meetings. The first established his advantage, and Saturday’s unanimous verdict confirmed it on ONE Championship’s stage.
