Mauricio Ruffy’s knockout threat meets a steep Tsarukyan price at UFC 331

There is an important sample caveat. Ruffy’s 83 percent finish rate on wins comes from only six archived victories, not a deep career-wide sample. Six knockdowns in 10 tracked rounds are meaningful evidence of danger, but they do not establish that the same pace will persist over five rounds or against every opponent.

The phase-control question is bigger than the knockout numbers

Ruffy has landed no takedowns and attempted no submissions in the tracked data. His 10 recorded rounds contain only two minutes of control time. Those figures do not make him one-dimensional by themselves, but they show that his demonstrated winning offense is overwhelmingly strike-led.

His 86 percent takedown defense is therefore the pivotal number. If it holds, Ruffy gets more time at distance to deploy his accuracy and head-focused attack. If it fails, his strongest statistics can become less relevant because takedowns and control reduce both exchange volume and clean knockout opportunities.

The packet does not include Tsarukyan’s round-level or career metrics, so there is no responsible way to quantify how Ruffy’s takedown defense matches up with Tsarukyan’s entries, chain wrestling or control. The outside report notes Tsarukyan’s recent wrestling success, but that is not enough to price a takedown prop or declare that Ruffy’s 86 percent defense will collapse.

This missing matchup data cuts both ways. It prevents a confident case for laying more than three dollars on Tsarukyan, but it also blocks the cleanest argument for taking the underdog. A strong aggregate defensive percentage does not reveal how Ruffy responds to repeated attempts, mat returns or sustained pressure over championship distance.

Five rounds widen both the opportunity and the uncertainty

Ruffy has absorbed 3.83 significant strikes per minute while defending 59 percent of incoming significant strikes. Those are not numbers that guarantee low-risk striking minutes. His style creates offense, but it also allows opponents enough contact to complicate a pure knockout thesis.

His recent history reinforces the tension. Three of his last four wins ended inside two rounds, yet his loss to Benoît Saint Denis came by second-round submission. Ruffy has been finished once in the seven-bout archive. The relevant betting point is not that one result predicts another; it is that his downside has appeared when a fight moved away from his preferred striking finish.

The scheduled five rounds also make total-rounds and fight-goes-the-distance markets mechanically interesting, but no prices for those markets are included in the observed board. Ruffy’s finishing profile points toward volatility, while the absence of extended five-round data creates uncertainty about both his late output and his defensive durability. Without an actual total or distance price, the evidence identifies the question rather than an actionable wager.

The board rewards shopping, not conviction

Anyone backing Ruffy had a meaningful choice between +235 and +260. That 25-cent difference matters for the same outcome and requires no additional fight prediction. Tsarukyan bettors had a narrower but still relevant range of -310 to -325.

The harder decision is whether either side clears its price. No graded projection is available, and the packet lacks opponent-level statistics needed to test the central grappling matchup. Ruffy’s power and accuracy establish a credible upset mechanism, not a complete handicap.

For now, the most defensible betting adjustment is selective rather than directional: use only the top moneyline number if backing Ruffy, and treat any knockout-method price as an extension of his actual route rather than an automatic value play. His head-strike concentration, six knockdowns and five stoppages among six archived wins support that route. The small sample, lone submission loss and unknown response to Tsarukyan’s specific grappling pressure argue against overstating it.
