I think Salido caused Juan Ma so many problems because of his style. Salido's method of primarily coming in head low and attacking with hooks, gave Juan Ma a limited amount of target to hit. Juan Ma was struggling to hit Salido clean throughout much of the fight. Meanwhile, Juan Ma stood up more straight and was an easier target for many of Salido's hooks. Someone in Juan Ma's corner should have given him some kind of tips on how to adjust, but I'm not sure if that ever happened. I think when Juan Ma finally scored the one knock down, it was because Salido made the mistake of throwing this half hearted jab. But aside from that, Juan Ma didnt have many good opportunities to land hard clean punches. I think Juan Ma's best attempt where he at least tried to do something different was where he fought Salido in close toward the end. But it was too late because he was already tired. Plus Salido is seemingly the more experienced when it comes to infighting.
