Despite being comfortably under the limit this isn't the lightest she's been, and she was actually just 99.5lbs for her last defense, just over a year ago. Despite being a 48 year old she in great shape and not looking ready to give up the title, but she did look very small, even at the smallest weight in professional boxing.
The challenger on the other hand made weight and came in spot on the 102lb limit. At the weigh in she looked much bigger than the champion, have several inches of height advantage and a naturally thicker, wider, look to her.
