This is a decent fight for Alamo after being out the ring for so long however it’s one I expect him to win.
Yomar Alamo fights on the back foot generally and is a decent boxer though not a huge puncher. He’s got 19 fights so does have some experience and is currently 18-0-1.
Jesus Alberto Beltran is 17-3-2 with 10 knockouts and is likely to be the fighter on the front foot in this fight. He’s got respectable power though his technical skills aren’t great.

I think Yomar Alamo will win a decision boxing off the back foot because hes better technically and has been more active while Beltran hasn’t fought for over 14 months.
