Ernesto Mercado stopped veteran Juan Carlos Burgos in the second round of their super lightweight clash on Friday night, June 19, 2026. Fighting at Thunder Studios in Long Beach, California, the 24-year-old Mercado secured the knockout victory by dropping Burgos twice in the second frame. The win maintains Mercado’s unblemished professional record and marks a significant milestone as he becomes the first fighter to stop the durable Mexican veteran.
The scheduled 10-round contest took place on the undercard of the Ashton Sylve vs. Joseph “Jo Jo” Diaz main event, broadcast live on DAZN. Ernesto Mercado entered the ring as an overwhelming betting favorite with odds as wide as -2500. His performance lived up to those figures as he utilized superior speed and power punching to control the fight from the opening bell, forcing the 38-year-old Burgos onto a defensive footing.
The breakthrough came quickly in the second round. Ernesto Mercado found openings with clean, explosive shots, eventually floorring Juan Carlos Burgos twice. One of the decisive blows was a crushing left hook that left the veteran unable to recover from the sustained attack. The referee halted the contest shortly after the second knockdown, awarding the knockout to the man known as “Tito.”
Impact of the victory on the super lightweight rankings
With this result, Ernesto Mercado improves his record to 19-0 with 18 knockouts, continuing a streak where he has stopped five of his recent opponents. Juan Carlos Burgos, a former world title challenger and nephew of former champion Victor Burgos, sees his record fall to 36-9-3. This defeat represents the first time Burgos has been stopped in his lengthy career, which includes notable distances against elite opposition.
Mercado’s rise in the 140-pound division follows a successful amateur career where he posted a 278-11 record and served as a 21-time national champion. He entered this bout with fresh momentum after signing with DMG Boxing on June 3, 2026. Prior to this victory, Mercado had been building his resume with notable wins over Antonio Moran by sixth-round knockout in December 2025 and Jose Pedraza by fourth-round stoppage in January 2025.
The Pomona native has frequently voiced frustration regarding his ability to secure top-tier opponents. Despite fans roast Shakur Stevenson on social media for various out-of-ring antics, the champion remains a high-value target for rising contenders like Mercado who believe they are ready for the world title stage.
Ernesto Mercado call-out focuses on Shakur Stevenson
In his post-fight interview, Ernesto Mercado wasted no time identifying his preferred next opponent. He specifically targeted WBO light welterweight champion Shakur Stevenson, expressing confidence that his own boxing ability and power could overcome Stevenson’s vaunted defense. Mercado noted that he has seen similar styles throughout his extensive amateur career and simply needs the professional opportunity to prove he can “take him out.”
The call-out wasn’t limited to Stevenson alone. Ernesto Mercado also named several other prominent figures in the division, including Keyshawn Davis, Ryan Garcia, Devin Haney, and Frank Martin. By naming the elite of the super lightweight landscape, Mercado is positioning himself as a hungry challenger willing to bypass the traditional slow-build of a prospect.

Strategic future for DMG Boxing’s new signee
As a free agent who recently joined DMG Boxing, Ernesto Mercado appears to be seeking the fastest route to a world title. His victory over Juan Carlos Burgos was a calculated risk against a veteran known for his “granite” durability. By ending the fight in just two rounds, Mercado has sent a message to the rest of the division that his power is a legitimate equalizer against experienced defensive fighters.
The 140-pound division is currently in a state of high activity, with several champions weighing their next moves. For Mercado, the objective remains clear: continue the high activity rate that has seen him fight five times since early 2024 and maintain his 94% knockout ratio.
Whether the big names like Stevenson or Haney will engage with a high-risk challenger who currently lacks the backing of a major legacy promoter remains to be seen. However, by systematically dismantling respected veterans like Burgos, Ernesto Mercado is making it increasingly difficult for the division’s elite to overlook his presence.
