JJ via UD. I'm not counting out Rose though, I'm actually very excited for this one than I have been for some of Joanna's other fights.
If Joanna beats Rose then that's 4/5 of the Top 5 (Tecia's the only one left) and 5/10 of the Top 10 (Esparza who's #7). JJ's starting to slowly clear the division out. I'm expecting whoever wins the Tecia vs. Michelle fight to challenge the champ after this one next (That is if they do Torres v. Waterson, which they should). If they don't go with Torres vs. Waterson then set Torres up with the winner of Herrig vs. Casey.
Wouldn't be surprised if Joanna moves up to 125 soon, the 115 division is running out of contenders.
