Vitals, record, nickname and camp come from the public UFC fighter register and are current, not a snapshot of fight night. UFC bouts, finish rate and every storyline line are counted off the official UFC fight record. A tick marks the side holding the raw edge in that row — longer reach, taller, younger, more bouts, a higher finish rate. It is a fact about the tape, not a prediction, and rows with no clean comparison (record, stance, gym, hometown) carry no tick at all. Any row we cannot fill on both sides is left out rather than half-drawn. Streaks, bout counts and finish rates are as they stood going into this fight — this bout and everything after it is excluded from the count.

Round by round

Every round the fight went, shaded by where the significant strikes actually landed — the takedowns, control time and knockdowns beside them, and how the three judges scored that round.

Significant strikes, takedowns, control time, knockdowns and submission attempts exactly as UFCStats recorded them for this bout, round by round. Zone percentages are that round’s landed head, body and leg counts over their own total — raw arithmetic, nothing modelled or smoothed. A round in which a fighter landed nothing shades empty and reads zero; it is never filled in from the round before.

Yana Santos

0.78takedowns / 15 min

Career UFC takedown rates exactly as UFCStats publishes them: takedowns landed per 15 minutes, completion rate, submission attempts per 15 minutes, and the share of takedowns tried on them that they stuffed. Attempts per 15 is the one derived figure — landed ÷ completion rate — and it is omitted wherever either input is missing. UFCStats writes 0% where no attempt was recorded at all, so a percentage of exactly zero reads “n/a” here rather than as a measured rate. “Field” is the average fighter in that weight class, or across every division where a class is too small to average. Rate bars run to the population’s 95th percentile (5.00 takedowns / 15m); a fighter above it pins the bar. Percentages are drawn on their own axis.
