Berto vs. Ortiz catchweight: "145 plus one." Explain please?

[xzworks]

i don't see any problem with 145 coming on weight..the real problem is getting over 147..

I mean WTF you're either fighting at the welterweight limit 147 or you're not.

exactly. except for 50 years of boxing you're exactly right.

Look how tired berto is.. Like i said.. Cottonmouth. All teh evidence was in the weigh in, you could clearly see bertos lips and tell he would become lax.

Berto weighed in at 145 for his previous fight vs. Hernandez.

He weighed in at 145.5 (under the "145 plus one" catchweight) for Ortiz, so I don't think it affected him.



Back on topic, I'm still curious what "145 pounds plus one" means, contractually speaking.
