Cotto's welterweight belt is on the line!!!

If it's between 140 and 147, then it's a welterweight fight. That's what a welterweight fight is. 145 is between those weights, so it's a welterweight fight.

So in your opinion there are no catchweights?

Sure, but a catchweight simply means that the normal limit for a weight class is moved down. But the limit of a weight is NOT what makes it a fight in a particular weight class. The weight class can be any weight between one weight and another. 170 for instance is a light heavy fight because it is above 168 but below 175. I don't see why this is so difficult to understand.

Maybe, I'm not making my case clear enough.

The limits of the weight class are precisely what makes a fight in a particular weight class. In this case 141 at the low end and 147 at the high end is defined by ALL institutions of professional boxing to define the Welterweight class. Should boxers choose to come in at 142, 146 whatever they are fighting within the RECOGNIZED weight class limits.
Now, the term catchweight comes into play when the official recognized limits of weightclasses are moved and therefore by definition cease to adhere to the established limits of a weightclass.

This is a catchweight fight.

I have to go to a movie now, we can continue later.
