We Want Picks Betting desk called 55 of 87 We Want Picks: predicted Jones · to win. Actual Mederos · KO/TKO R2. Result: Miss.
Reads Mederos as almost too technical and too athletic for this match-up, and expects Jones's pressure and grit to deny him room to breathe -- Jones will keep walking forward even while eating two strikes to one. Mederos's only path is to stay clean, stay safe and out-athlete him.
“So, I think Mason Jones wins this fight just by being violent and willing to take a beating.”
Track record: winner called in 55 of 87 resolved picks.
JakeGerberMMA Analyst called 44 of 62 JakeGerberMMA: predicted Jones · Decision. Actual Mederos · KO/TKO R2. Result: Miss.
Calls it a good, competitive fight and rates Mederos durable, but gives Jones the edge as the better grappler with more power. Expects Jones to drain Mederos's gas tank, then open up on the feet -- walking him down and advancing forward in a way that scores well with the judges. Scores it 29-28.
“It's going to be Mason Jones via a dog fight. I think he gets it done by a competitive decision.”
Track record: winner called in 44 of 62 resolved picks, 10 a perfect call.

Pre-fight analysis — how we saw it going in
Case for Mederos
Mederos barely wrestles at all, averaging 0.23 takedowns per 15 minutes, so his route is to keep the fight standing and win the striking exchanges outright. His 83% takedown defence is the highest of the two and is what he needs to lean on.
Case for Jones
Jones brings the more varied attack, averaging 3.48 takedowns per 15 minutes alongside a marginally higher striking output. His route is to make Mederos carry weight and fight off his back rather than trade cleanly.
What We Were Watching For
- Whether Jones commits to his wrestling early or feels out the striking first — he is the only one of the two who shoots with any regularity.
- Mederos’s 83% takedown defence against the highest takedown rate he has faced on this card.
- Striking volume is near-identical (5.46 against 5.98 landed per minute), so the separation is likely to come from grappling, not output.
- Both absorb a similar amount (4.58 against 4.45 per minute), which points to a competitive rather than one-sided exchange.
