Ravena Oliveira enters as a significant favourite at -305 over Shanelle Dyer in this women’s strawweight prelim. Oliveira’s Brazilian MMA credentials and technical advantage at 115 pounds make her the dominant pick, but Dyer’s home crowd energy and determination are genuine factors in a closely watched London prelim.
Fighter Breakdown
- British strawweight fighting at home in London — the crowd support at the O2 is a genuine psychological advantage
- Motivated by the unique opportunity to perform in front of a home audience on one of the UFC’s biggest annual UK cards
- At +255, carries legitimate upset potential if the right sequence develops early in the fight
- Concern: Oliveira’s technical advantage at 115 pounds and the -305 favourite status reflect a fundamental skill gap that is difficult to overcome even with crowd support.
- Brazilian strawweight with the technical MMA skills and fighting IQ typical of South American women who compete at this level
- -305 favourite reflects a clear and consistent technical advantage across all areas of the fight at 115 pounds
- Comfortable performing away from home — travels well and produces consistent results regardless of crowd environment
- Concern: Must not underestimate Dyer’s home crowd motivation — complacency against a home fighter is the classic upset scenario in combat sports.
Oliveira wins clearly. The -305 favourite status reflects a genuine, consistent technical advantage that Dyer’s home crowd motivation cannot fully bridge. Oliveira should control pace and accumulate clean rounds throughout a fight where the outcome is rarely in serious doubt. Dyer will give maximum effort in front of the London crowd — that is guaranteed — but the fundamental skill differential makes Oliveira the confident pick across three rounds.
