I saw lots of haymaker punches from Casimero like he was trying to get a lucky punch that would end the fight, that's not how boxing works, he also lacks the basics. I think he is too impatient about winning and climbing the ranks to get his shot against Inoue but he doesn't notice that by doing this he is just making the gap longer.
After watching him against the Japanese Oguni I didn't see good boxing and I bet many Filipino boxing fans would feel the same. He is forcing a knockout but he ain't that young Casimero anymore. He should think about taking it slow and using his experience as his main weapon instead of fighting like a 25 year old boxer with lots of stamina reserved, he ain't that guy anymore.
In round 2, I saw him resting and breathing heavily from his mouth, which is why I have round 2 to Oguni because he took advantage of that and let his punches fly all over Casimero.
That's because Casimero is too excited to knock out Oguni in the fastest possible way underestimating Oguni's stamina and power but unfortunately, it backfires he is the one losing steam and getting hit a lot, and he may hit Oguni with his own punches but he is able to stand those punches.
While watching the fight I was wondering where Casimero's power went, those were the punches that hurt and knockout all his past opponents now it seems he cannot carry his power in the upper weight division if he cannot carry his power then he is just an ordinary fighter and Fulton can easily knock him out before he can go to Inoue.
