The UFC's official fighter rankings usually see at least a small amount of change after each event, but UFC Fight Night 30 provided very little fluctuation. Only two bouts on the whole card made anything change - the main event and the ladie's bout. But Lyoto Machida's headlining win over Mark Munoz did help him to because the second fighter in the brief history of the rankings to be included in two weight classes.
You can check out the full rankings here, and use the dropdown menu to see the individual picks of the five BE contributors (myself, T.P. Grant, Chris Hall, Fraser Coffeen, and Stephie Daniels).
Machida entered the middleweight rankings as the number five challenger with his big win. Munoz dropped two spots to seven, while Francis Carmont and Costa Philippou almost moved down one spot (to eight and nine respectively). Tim Boetsch fell out of the top ten with Machida's arrival.
In the light heavyweight division, Machida managed to stay in the top 10 despite the division change. He fell four spots to ten, while allowed Dan Henderson (6) Chael Sonnen (7), Gegard Mousasi (8), and Mauricio Rua (9) to move up one. I'm sure Machida will drop off of this list in the next few weeks.
Finally, Jessica Andrade's win over Rosi Sexton earned her the number ten spot, bumping Rosi off the list.
And that's it.
