Really like Martinez here, seems like the bet of the card. All the downside is with Cub, age, dropping a weight class, he's pretty much a pure striker so he's reliant on reflexes and speed. Martinez has really found a groove lately, I think being active and taking shorter breaks between fights is good for him.
I think Cub can be dangerous in the first, but outside of that Martinez should take over. Cub is open to the low kicks (See the Pineda fight) and body kicks (Giga) and Martinez is a really tactile and quick kicker, very consistent too.
Dusko should have every opportunity against Wright, much more well rounded and capable but Wright is dangerous and powerful and will go balls out in round one and there is every chance he catch Dusko if he's not carful. Unders/DGTD are obvious, but the juice will big.
Askarov/Royval is a complicated one, I kind of think Royval is somewhat of a meme/fraud. He's got a very tricky style to gameplan for but his technical abilities and fundamentals are really none existent. He throws arm punches, spins and gives his back, doesn't really make use of he reach and length because he doesn't seem to get a read on the distance. He also has no physicality, guys will throw him to the floor effortlessly, he has no hips, no ass, no base under him. With all that, he sets a crazy pace, throws so much volume, makes every position a battle, he doesn't allow guys to just settle. I think he's weak on bottom but he never gives up or stops squirming, he moves into weird angles and gets his butterflies in and ties up arms.
Askarov is pretty much the other end of the spectrum, one punch at a time, technically sound counter boxing and a positional control wrestling and grappling game.
Generally Royval has lost to these guys who are more controlled and technically 'correct', Moreno, Pantoja, very close fight with Bontorin - Lower volume, better boxers who have more traditional BJJ
