Jose Aldo has been insisting for a month that 2019 will be his final year in the fight game. On Saturday, though, he made it clear that he's not done yet, battering rising featherweight contender Renato Moicano for a second-round TKO in the co-main event of UFC Fight Night: Assuncao vs. Moraes in Fortaleza, Brazil.

It was a turn-back-the-clock performance by Aldo (28-4) both in winning the fight and in celebrating the victory. After a feeling-out first round in which neither man seized an advantage, Aldo came out for the second and almost immediately hurt Moicano, sending the 29-year-old into retreat. Aldo pursued him with a measured relentlessness and landed with precision and power until the referee pushed him away at 44 seconds of the round.

Aldo then raced across the Octagon and leaped over the cage to celebrate with his cheering countrymen in the deafening Northeast Olympic Training Center. It was reminiscent of Aldo's celebration amid the Rio de Janeiro crowd after his victory over Chad Mendes in a 2012 title defense.

"Tonight I came in here as the underdog. Nobody believed in me. But I knew I would have you guys' support," Aldo told the crowd, through an interpreter, during an interview in the Octagon. "In life, a lot of times, people say that you can't do something. You have to believe in yourself. You have to chase your dreams."

While Aldo is just three years older than Moicano, experience was heavily on his side. When Moicano made his pro debut in May 2010, Aldo was already the best 145-pounder in the world, a dynamic champion in the midst of an 18-fight winning streak. That run and the title reign ended in 2015 in a 13-second loss to Conor McGregor, and since then Aldo has lost twice more, both times to current champion Max Holloway.

But losses to top-level opponents only obscured the sustained greatness of Aldo, whose big-fight experience helped him close the show. Once he hurt Moicano, he smartly pursued the finish like a veteran while Moicano had nowhere to go to save himself.

"I wanted to vary my shots," said Aldo. "Hit him high, hit him low."

Moicano (13-2-1), a former champion in the Jungle Fight promotion in Brazil, had lost only once previously, in a 2017 Fight of the Night submission against recent title challenger Brian Ortega.

Demian Maia defeats Lyman Good by first-round submission

Maia did what Maia does, pursuing the takedown right from the start and methodically working toward a submission, which he got at 2:38 of the first round via rear-naked choke.

The 41-year-old Brazilian (26-9), who had lost three in a row starting with an unsuccessful challenge of welterweight champion Tyron Woodley in 2017, stalked Good (20-5, 1 NC) right from the moment the referee waved the fighters together. And once he got the New Yorker against the cage, Maia took him down and secured back position, which he maintained even after Good got back to his feet.

It took awhile for Maia to get his arm under his standing opponent's chin, but as soon as he did, his squeeze was too hard to withstand and he became the first to finish Good. It was Maia's 10th submission win in the UFC, tying him with Royce Gracie in second place, behind Charles Oliveira, who got his 13th UFC sub in the fight right before Maia's.

Maia also put himself in a tie with some other all-time greats in the category of victories, according to ESPN Stats & Information, as his 20 UFC wins are the second most in company history, tying him with Georges St-Pierre and Michael Bisping, behind Donald Cerrone's 22.

Charles Oliveira defeats David Teymur by second-round submission

Not-so-breaking news: Oliveira won a UFC fight by submission. The 29-year-old Brazilian extended his winning streak to four, finishing Teymur with an anaconda choke 55 seconds into Round 2.

For Oliveira (26-8, 1 NC), it was his 14th UFC victory, his 13th by submission, most in the promotion's history. He has 18 subs in 26 career victories overall.

It's almost as though Oliveira can get a submission with his eyes closed, and on this night that was practically the case. In the first round, the fight was halted twice after Teymur poked the Brazilian in the right eye. In an interview in the cage after the fight, Oliveira said he told his coaches between rounds that he could not see out of the eye.

Teymur (8-2), who came in on an eight-fight winning streak, had a point deducted after the first eye poke. He also had problems with his own right eye, after an Oliveira kick caught him late in Round 1. Then, early in the second, Oliveira stunned him with an elbow and a flurry of punches, and it looked like a TKO in the making. But Oliveira took the fight to the canvas and latched on one of his trusty chokes.

Johnny Walker defeats Justin Ledet by first-round TKO

Walker danced on his way to the Octagon, then rested against the cage during introductions, as if he were out for a night of leisure. And then he got down to business in a hurry, collapsing Ledet with a spinning back fist just 15 seconds into their light heavyweight bout.

Walker (16-3), who has 13 first-round finishes, first touched Ledet with a head kick, then threw the spinning maneuver that put the Texan on the canvas.

As perfect as that fight opening sounds, though, Walker then made a mistake that could have cost him the win. With Ledet dazed on the mat, Walker threw a kick that, had it landed, likely would have resulted in his disqualification. But the kick missed its target, and Walker pounced on his opponent with punches until the referee jumped in.

For Ledet, it was his second straight loss after a 9-0 start to his career.

Livinha Souza defeats Sarah Frota by split decision

Souza used her grappling advantage and maintained distance on the feet to eke out a close one against the bigger Frota, who had missed weight by seven pounds on Friday to turn this scheduled strawweight bout into a 123-pound catchweight contest.

Souza (13-1), a former Invicta champion who has won four in a row since losing her belt in 2016 to UFC veteran Angela Hill via split decision, was in control early but appeared to sag as the fight wore on. However, even though she was being outstruck, she avoided any heavy damage in the Brazil vs. Brazil matchup.

Frota, making her UFC debut, lost for the first time in her 10-fight pro career.

Markus Perez defeats Anthony Hernandez by second-round submission

Perez turned a back-and-forth middleweight fight in his favor with a body kick that sent a hurt Herrnandez into retreat, then swiftly took the fight to the canvas and finished with an anaconda choke at 1:07 of the second round. The Brazilian (11-2), who had lost two of his past three, handed Hernandez (6-1, 1 NC) his first career defeat.

Perez, a 28-year-old from Sao Paolo, is the 15th fighter in UFC history to win by anaconda choke, according to ESPN Stats & Info. Only two fighters, Charles Oliveira and Phil Davis, have done so more than once.

Mara Romero Borella defeats Taila Santos by split decision

Borella got back on the winning track by a slim margin, taking two of the three 29-28 scores in her first fight since seeing a seven-fight win streak end last year.

The 32-year-old Italian (12-5, 2 NCs) closed the distance constantly to make it a grappling match, and she was in control for the first two rounds. But then Santos (15-1), who suffered her first career loss in her UFC debut, got into a standup rhythm in the third and landed consistently. She never hurt Borella to the point of coming near a finish, though, and fell just short.
