Burgos, of New York, out-landed Swanson in total strikes 147 to 132, according to ESPN Stats & Information data, and caused visible swelling on Swanson's face with his jab and boxing combinations. Swanson, 35, enjoyed his share of success, as well, bloodying Burgos' mouth in the final round.
The hodgepodge of judges decisions reflected how close each individual round was. Burgos won 30-27 and 29-28, according to two judges, while a third saw it 30-27 for Swanson.
For Burgos, 28, it improved his UFC record to 5-1. He answered Swanson's barrage of leg kicks with kicks of his own and thwarted a late takedown attempt that might have proved to be the difference had Swanson taken him down. Swanson fell to 0-4 in his last four appearances, which is the longest skid of his career.
Brunson beats Theodorou in awkward stand-up bout
Brunson, 35, didn't appear bothered by the crowd's reaction, and it's easy to understand why. If Theodorou is one thing, it's awkward. Opponents have always struggled to find their rhythm against Theodorou, but Brunson was able to secure the win with timely takedowns and a couple of submission attempts.
"I was doubting myself," said Brunson, who came in on a two-fight skid. "I never lack confidence, but there is just doubt there. Am I getting older? To get it done against a cardio machine, it felt good."
Brunson scored takedowns in all three rounds and threatened to submit Theodorou with a rear-naked choke in the first round. Theodorou proved hard to keep down, however, and always managed to work back to his feet after a Brunson takedown -- including a violent, Octagon-shaking slam in the third.
Brunson picked up his first win since October 2017. Theodorou, of Ontario, suffered his first loss in four bouts.

Dvalishvili dominates Katona over three rounds
Originally from the country Georgia, now fighting out of New York under Ray Longo and Matt Serra, Dvalishvili took Katona down at will and landed some hard shots from top position, particularly in the opening round. All three judges scored it in his favor, 30-27 -- and improved his UFC record to 2-2.
"To be honest, it was a very difficult fight for me," Dvalishvili said. "It was fourth fight on my contract. My first two fights, judges take from me. If I lose this fight, maybe I go home to smaller organization. I don't want to. I want to stay in UFC. I want to fight with best guys, and I have best team behind me."
According to ESPN Stats & Information data, Dvalishvili converted 5 of 9 takedown attempts. He took Katona down in each of the three rounds, which allowed him to cruise to the clear-cut win.

Harris blows past Spivak in quick KO
Harris, 35, has had an up-and-down career since he debuted with the UFC in 2013. He briefly lost his spot with the promotion in 2014 and has never enjoyed a winning streak longer than two.
Saturday's performance was a welcome one for the boxing-heavy martial artist. He immediately put Spivak on the defensive with a lead left hand and followed it with a flurry along the fence that had the Ukrainian heavyweight covering up. It was Harris' fifth win in the UFC -- and when he has won, he's had no trouble putting opponents away. All five of his wins are via TKO.
"I know my hand speed is the best in the division," Harris said. "When I let them go, they don't know what's happening."
Sanchez survives second round, secures decision
Middleweight Andrew Sanchez (11-4) managed to survive a terrible second round, en route to a unanimous decision win over UFC newcomer Marc-André Barriault (11-2). All three judges awarded Sanchez the first and third rounds -- but he was nearly finished in the second.
Barriault, of Quebec, found his range midway through the middle frame and proceeded to light Sanchez up on the feet. He snapped his head back with multiple uppercuts in tight and bloodied him with a left hook and right cross. Sanchez appeared badly hurt after the round but recovered well before the third.
He turned to his wrestling heavy in the final five minutes, and although he never really appeared to hurt Barriault with any offense, he slowed and controlled the rest of the bout.
"He hurt me, buzzed me, I really had to dig deep," Sanchez admitted. "I had to take him down. It may not be exciting, nobody likes wrestling, but you can't get away from me."
For Sanchez, it is his second win in a row and fourth victory overall in the UFC.
