Josh Atencio, who joined the Seattle Sounders as an academy player in 2016 and turned professional with Tacoma Defiance in 2019, is transitioning to a center back position for the 2025 season.

As he makes this transition, Atencio will retain the No. 8 jersey, a number he has coveted since childhood.

Sounders general manager Craig Waibel praised Atencio's athleticism and potential to evolve into an elite player in his new role.

The Sounders are currently facing a lack of experienced depth at the center back position, and Atencio's physical training and adaptability are expected to help address this issue.

Head coach Brian Schmetzer is preparing the team to potentially utilize three center backs, which would provide tactical flexibility in their formation.

Atencio's first match as a designated center back took place during an international friendly against Puskás Akadémia FC, where he contributed to a 2-0 victory.

Last season, Atencio played center back sporadically due to injuries and suspensions affecting team lineups.

The Sounders are focusing on roster versatility as they gear up for multiple tournaments, including the CONCACAF Champions Cup and FIFA Club World Cup.

In the same friendly match where Atencio debuted as a center back, teammate Pedro de la Vega also made an impact by scoring a goal and providing an assist, marking his return from injury.

In roster news, the Sounders made their first cut of the season by releasing forward Braudílio Rodrigues, who did not make an MLS appearance due to injury.

In other soccer news, Sounders legend Ozzie Alonso has expanded his involvement in the sport by investing in the ownership of Spokane's Zephyr FC and Velocity FC.

Additionally, an application process for volunteers for the FIFA Club World Cup has opened, allowing eligible U.S. citizens to apply for positions during the event scheduled for June 2025.
