Behind a dominating five-round decision victory over Anthony Pettis, new UFC lightweight champion Rafael dos Anjos finds himself ranked ninth in the overall pound-for-pound Top-15.
Dos Anjos won the belt this past weekend and immediately entered the rankings. The loss dropped Pettis to No. 10 overall.
Cain Velasquez, Ronda Rousey, T.J. Dillashaw and Robbie Lawler all benefited from the change, moving up.
Alistair Overeem climbed to eighth in the heavyweight division after defeating Roy Nelson, though he still remains ahead of Ben Rothwell, who knocked him out last year. Nelson fell to 10th.
Antonio Rogerio Nogueira and Fabio Maldonado flipped for 12th at 205 pounds, while Thales Leites and Michael Bisping did the same for ninth at 185.
Kelvin Gastelum moved ahead of Jake Ellenberger and into 10th at welterweight, while Ryan LaFlare and Gunnar Nelson flipped for 14th. At lightweight, Edson Barboza and Myles Jury each moved ahead of Josh Thomson and into seventh and eighth, respectively.
Atop the featherweight rankings, Chad Mendes moved back ahead of Frankie Edgar and into the role of No. 1 contender to Jose Aldo, while Mitch Gagnon and Alex Caceres switched 14th and 15th at bantamweight.
The flyweight division saw Henry Cejudo debut this past weekend and best Chris Cariaso, and he was rewarded by being ranked 10th. Jussier Formiga and John Moraga flipped for fourth, while Cariaso, Tim Elliott and Wilson Reis each fell.
Heather Clark and Seohee Ham each moved up a position in the women’s strawweight division, while Paige VanZant and Angela Hill fell one spot each. At 135 pounds, Germaine de Randamie jumped Raquel Pennington for 14th.
