Miguel Berchelt - 136 lbs
Oscar Valdez - 136.4 lbs
So the two fighters are within the limit now, and should be fine shredding the excess weight in the last 2 weeks leading to their fight.

Looking at Miguel Berchelt, looks like he is the more physically fit, after all he is the champion and definitely comfortable in this weight. Surprised though that Valdez is somewhat getting bigger and then he has to cut weight more weight in 14 days.
I understand that he is coming up in weight and that is good, but it seems he overdo it. Anyway, I'm no expert here, just sharing my own opinion.
I think Oscar Valdez is good to go, his abs is visible in the images, so when he cut down to 130 lbs, there will be no significant effect on his body, in my opinion. Of course, Miguel Berchelt will be the bigger guy because this is his natural weight.
But there are a lot of boxers going up in weight throughout boxing history that upset the champion so this is still 50:50 and it will definitely can go as one of the best fight for 2021.
Agree, the thing we hear from Oscar Valdez is that he has the best trainer behind and although he is the underdog here, it could be good for him and his team as they could really be motivated to upset Miguel Berchelt, and odds are really very attractive for us gamblers.
And as Oscar Valdez's body matures I think he will be a perfect fit for the 130 lbs division and it seems that squeezing 126 lbs will be much harder than losing the additional 6 lbs in this pre weight.
