This is a good fight and a nice test for Magsayo who is having his second fight in the USA. If he wins this fight he may challenge for a world title within one or two fights. For Hermosillo this is a great opportunity.
Mark Magsayo is a big puncher who seems very strong for the weight. Hes decent technically and isn’t afraid to get into a bit of a war. His defence isn’t bad but I wouldn’t say its great either. His competition hasn’t been great so far though there are a few capable opponents on his resume.
Rigoberto Hermosillo is generally a come forward fighter that has decent power. I wouldn’t describe him as your standard brawler as he does normally use his boxing to push forward. His defence isn’t great and hes been dropped by lesser punchers than Magsayo.

I think Magsayo will win this fight by knockout and be the first person to stop Hermosillo because Hermosillo likes to come forward but has a lackluster defence which will play right into Magsayo’s hands or in this case fists.
