[11] Guevara debuted for Pro Wrestling Guerrilla (PWG) in its 2017 Battle of Los Angeles tournament, advancing to the quarterfinals.

Guevara was a cast member for season four of Lucha Underground, the scripted TV show AAA co-produced with the El Rey network.

[21] He won the AAA World Cruiserweight Championship at the Triplemanía XXVI annual event on August[22] before losing it to Laredo Kid on February 16, 2019.

[37] On June 22, 2020, Guevara was suspended by AEW after it was revealed that he made an inappropriate joke about wanting to "go rape" WWE wrestler Sasha Banks during a podcast in January 2016.

Later that day, Banks announced that she and Guevara were in contact with each other, that he had apologized to her, and that they had engaged in an "open discussion" to help him understand the severity of his comments.

[39] Guevara returned on the July 22 episode of Dynamite, disguised as Serpentico, as he interfered to help Jericho and Hager defeat Jungle Boy and Luchasaurus in a tag team match.

He would reveal that he had set up a camera in The Inner Circle's locker room, which recorded MJF convincing Jake Hager, Santana, and Ortiz to turn on Chris Jericho.

However, MJF would state that he had already begun creating his own group, which led to Shawn Spears, Wardlow, FTR, and Tully Blanchard coming out and attacking The Inner Circle.

[49] Two weeks later on April 7, Chris Jericho (along with the rest of the members of the Inner Circle) would challenge The Pinnacle to a Blood and Guts match.

[50] At AEW Blood and Guts, The Pinnacle would defeat The Inner Circle, after Guevara forfeited the match to save Chris Jericho from being pushed off the top of the cage by MJF.

At Double or Nothing, The Inner Circle would win after Guevara hit a 630 senton on Spears in the ring after an extensive backstage brawl between the two, keeping the group alive.

On the June 30th edition of AEW Dynamite, Sammy Guevara would lose to MJF after Spears hit him with a chair to the head.

[53] On December 25, at the special Holiday Bash episode of Rampage, Guevara lost the title to Cody Rhodes, ending his reign at 87 days.

[54] A TNT Championship rematch between Rhodes and Guevara was scheduled to take place at Battle of the Belts I on January 8, 2022.

An interim TNT title was created as a result, with a match between Guevara and Cody's brother, Dustin, being scheduled at Battle of the Belts instead.

[55] On January 26 at AEW Beach Break, Guevara defeated Cody Rhodes in a ladder match to unify the belts, becoming the undisputed (and two-time) TNT Champion.

[57] On the February 9, 2022, episode of AEW Dynamite, the Inner Circle had a team meeting that ended with Sammy Guevara throwing his vest and walking out.

[58] At Revolution 2022, Guevara would win a Tornado tag team match with Allin and Sting over Andrade El Idolo, Matt Hardy, and Isiah Kassidy.

Sammy would continue his feud with Scorpio Sky but with the inclusion of his girlfriend Tay Conti due to the official signing of Paige VanZant in AEW.

At Battle of the Belts II, Sammy Guevara successfully ended Scorpio Sky's undefeated streak with a low blow, winning his record-tying 3rd TNT Championship.

On June 26 at Forbidden Door, Guevara and Jericho, under the sub-unit of "Le Sex Gods" teamed with Minoru Suzuki defeating Eddie Kingston, Shota Umino and Wheeler Yuta.

[65] Instead, Guevara and Melo successfully defended the AAA Mixed Tag Team Championship against Ortiz and Ruby Soho.

On the April 19, episode of Dynamite, Guevara defeated "Jungle Boy" Jack Perry by countout with assistance from MJF in the semi-final of the Four Pillars Tournament.

[75] On the December 27 episode of Dynamite New Years Smash, Guevara returned to AEW as a face by confronting The Don Callis Family, before getting attacked by them.

Guevara's friends and fellow AEW co-workers, such as Fuego Del Sol, Griff Garrison, Alan "5" Angels, Isiah Kassidy, Dustin Rhodes, and (more recently) Aaron Solow and wife Tay Melo make frequent appearances, and the vlogs, instead of sticking strictly to a visual diary format, now include specific fictional storylines between the aforementioned wrestling personalities.
