This is crazy when you think about it, but then I looked it up to see the statistics.
2017- Carmella held it for 287 Days before cashing it in.
2018- Alexa Bliss held it for just 2 Hours, 52 Minutes.
2019- Bayley held it for 1 Hour, 25 Minutes.
2020- Asuka won but on RAW it was revealed that Becky was pregnant and that Asuka really won the RAW Women's Championship that Becky vacated.
2021- Nikki A.S.H held it for 1 Day.
2022- Liv Morgan cut a promo about waiting to cash in, then cashed in 2 hours later.
2023- Due to the PLE being on Saturday, you would be correct that it already makes Iyo one of the longest MITB holders for the Women.
