Oscar Maydon is celebrating his first-ever U.S. chart-topping single…

The 24-year-old Mexican singer’s Becky G-collaboration “Mercedes” has accelerated to No. 1 on Billboard’s Regional Mexican Airplay chart dated August 3.

The track marks Maydon’s his No. 1 on any U.S.-based tally; it’s Becky G’s second leader on the survey.

“Mercedes,” released April 11 on Kemosabe/RCA/Sony Music Latin, speeds 7-1 on Regional Mexican Airplay with a 49% vault to 6.4 million audience impressions in the week ending July 25, according to Luminate.

Becky G previously topped Regional Mexican Airplay with “Por El Contrario,” with the Aguilar siblings, Leonardo and Angela, for a week in March.

Narcocorridos singer Maydon, meanwhile, reigns in his second visit to the chart, after logging a No. 33 high through “Fin De Semana,” with Junior H, in August 2023.

The Mexicali, Mexico, native has tallied two prior No. 1s on the Mexico Songs ranking (part of Billboard’s Hits of the World charts menu).

“Volver Al Futuro,” with Junior H, led for a week in June after “Madonna,” with Natanael Cano, dominated for 11 weeks beginning in March. He made his first chart appearance when “Los Collares,” with El Padrinito Toys, entered Mexico Songs in January 2023. As “Fin De Semana” grew, he also hit a No. 36 high on the Emerging Artists chart that February.

Elsewhere, the gains in audience help “Mercedes” motor 11-4 on the overall Latin Airplay chart for its first week in the upper region. Maydon posts his first top 10 on the list, while Becky G secures her eighth and first since “Por El Contrario,” which became her sixth No. 1 in March.
