Once again dispatching her opponent via first-round armbar, Rousey's thrilling main-event win was the cherry on top of a very successful card.
While Rousey's stock is certainly on the rise, let's check out how all the main-card fighters fared.
While the stoppage may have been a bit premature, there was no denying that the old Robbie Lawler was back on Saturday night.
Rejuvenated back at 170, his return to the Octagon was a vintage performance, stopping Josh Koscheck with punches in the first round.
If he can continue to look this impressive in his future bouts, who knows what's next for this heavy-handed veteran.
One-time title challenger Josh Koscheck has always been a force in the welterweight division, but his current streak of losses may result in a pink slip if it continues to build.
With back-to-back losses to top-tier 170ers Johny Hendricks and Robbie Lawler, Kos needs a big win unless he wants to end up like Jon Fitch.
Kos needs to channel his inner finisher and start knocking people out again.
Halting a two-fight losing streak in a successful move to the welterweight division, Court McGee put on a solid performance in his win over Josh Neer.
The well-rounded former TUF winner can go from prospect to contender if he can keep on winning in the weight class.
The longtime veteran may be in jeopardy of being cut after suffering his third straight loss to Court McGee at Saturday's UFC 157.
After dropping a lopsided unanimous decision, the UFC's ongoing string of cuts may result in a pink slip for Neer, who previously lost Justin Edwards and Mike Pyle via first-round finishes.
At just 29 years of age, Neer has the time to turn things around.
"The California Kid" bounced back nicely from his failed shot at the interim bantamweight title, getting back into the win column with an impressive standing rear-naked choke win over vet Ivan Menjivar.
Fabe's only WEC and UFC losses have been in championship bouts, and he may be able to claw his way back to another one should he keep up his winning ways.
Another win or two should get him back into contention.
Despite an impressive Submission of the Night-winning performance at UFC 154, longtime vet Ivan Menjivar is just 1-2 in his last three fights.
The TriStar Gym product showed he still has some moves during Saturday's bout with Faber, but he got caught badly in a standing rear-naked choke, tapping out in the first round.
A loss in his next fight may mark the start of a steady decline in the veteran's career.
Despite coming away with a split-decision win over Dan Henderson on Saturday night, the lackluster performance didn't really do much to raise Lyoto Machida's stock.
The former champ got in a few good shots, but he was taken down a few times and did not push the pace at all in the final frame.
Dana White may still tap the karate ace for another shot at the belt, but if another contender wins impressively in the coming months, all of that might change.
Coming back from over a yearlong layoff, ring rust seemed to play a factor in Dan Henderson's lackluster return to the Octagon Saturday night.
Despite a few early takedowns and ground-and-pound shots, Hendo did not really do anything significant in the later rounds, resulting in a split-decision loss.
At 42 years of age, he's not getting any younger and missed out big on the opportunity to fight for another title.
While she may have come up short on Saturday night, Liz Carmouche's stock is definitely up after putting on such an impressive performance while making history at UFC 157.
Carmouche gave it her all and nearly finished the champ in the first round, proving that she's a danger to any woman at 135.
Everything went right for Ronda Rousey at UFC 157 as she made history in the UFC's first women's bout.
Surviving some early trouble before taking another opponent's arm in the first round, it couldn't have been a more perfect win for the champ.
With the winner of Miesha Tate vs. Cat Zingano the likely next challenger to her belt, I can't wait to see Rousey enter the Octagon again.
