After last weekend’s (Sat., August 5, 2017) night of fights from the Arena Ciudad de Mexico in Mexico City, Mexico, the flyweight rankings have seen a bit of a shake-up.

In the main event of the night, Sergio Pettis took home a dominant unanimous decision win over Mexico’s Brandon Moreno. After his win, Pettis climbed up the 125-pound rankings two spots to tie Wilson Reis for the No. 4-ranked spot. In a thin flyweight division, Pettis could have just solidified his case for the next shot at Demetrious Johnson‘s throne following his upcoming title defense against Ray Borg at UFC 215.
