Was Pacquiao the Only Fighter to Moved up 3 divisions in a span of 9 months?

Is there anybody else whose done that? 130 135 147 Directly Calzaghe took 10 years to move up one, he's ATG and Hall of famer, right?

Is there anybody else whose done that? 130 135 147 Directly Ever heard of henry Armstrong?

Joan Guzman could do it...if he cared enough.

Rjj 175 to 200 above No.. That's only a span of 2 divisions although the the pounds seems a little bit higher for Jones.
