Iwo Baraniewski
58% · KO/TKO
  • Baraniewski's 100% finish rate with four consecutive KO/TKOs, fueled by 11.35 SLpM at 57% accuracy, against a Menifield chin that has failed in R1/R2 twice in his last five fights
  • Menifield's 3-inch reach edge (76 vs 73) and 53% accuracy give him legitimate counter-KO equity, he just did it to Zhang Mingyang in round 1, and Baraniewski absorbs 8.65 SApM with only 52% defense
  • Menifield's 78% takedown defense means Baraniewski cannot bail out of a bad striking exchange; this stays a pure kickboxing match
  • Elo (55% Menifield) vs market (67% Baraniewski) disagreement resolves mostly toward the market because Baraniewski's rating is provisional, but the gap flags the +193 as a live price rather than a longshot
Write-up

Genuine tension between the two priors here: the market has Baraniewski at 67%, Elo has Menifield at 55%, but Baraniewski's rating is provisional on one rated bout so the Elo number is mostly Menifield's own 18-fight baseline. I side with the market but not at its price. Baraniewski is 9-0 with four straight first-round-style knockouts (Aly, Aslan, Lane, Tafa) and his UFC-sample numbers, 11.35 SLpM at 57% accuracy, describe a fighter who throws with intent from the opening bell. The problem is the other column: 8.65 SApM absorbed and 52% defense means he trades in the pocket, and Menifield at 53% accuracy is one of the heaviest single-shot punchers at 205, as Zhang Mingyang found out in May. Menifield's 78% takedown defense also removes the fallback Baraniewski has never needed. So this is a firefight where the older man (38, nearly 39) has the longer reach by 3 inches and has been knocked out in round 1 or 2 in both of his last two losses (Murzakanov, Oezdemir). Chin durability at this age is the deciding factor. Baraniewski's youth, output and layoff freshness (92 days, three fights in nine months) give him the edge to land first and land often, but Menifield's counter-power and small-sample noise on Baraniewski keep this well short of the -230 line. Decision is unlikely from either side; someone gets finished early.

64% · KO/TKO
  • Baraniewski lands 11.35 significant strikes per minute versus Menifield's 3.84
  • Baraniewski has higher striking accuracy, 57% versus 53%, but absorbs considerably more strikes
  • Menifield's low takedown rate provides limited evidence that he can consistently interrupt the striking exchanges
Write-up

Baraniewski's higher striking output and +2.70 significant-strike differential favor him in exchanges against Menifield's nearly even differential. His 8.65 strikes absorbed per minute gives Menifield a substantial counterstriking opportunity. Missing sample sizes limit confidence in the extreme rates, but the supplied numbers favor an early Baraniewski stoppage.
