Díez first joined Gernika KESB in 2015 as a rising wing player, quickly earning respect from teammates and coaching staff for her relentless work ethic, tactical intelligence, and natural ability to lift team morale during high-pressure matches. In 2017, she was unanimously named team captain, a role she held for five consecutive years until her retirement in 2022 due to a recurring knee injury. During her tenure as captain, Díez led Gernika KESB through one of the most successful eras in the club's history: she guided the team to promotion from the second-tier Spanish women's handball division to the top-flight Liga Guerreras Iberdrola in 2019, secured two consecutive Copa de la Reina semi-final appearances, and helped grow the club's home match attendance by 120% over four years, as local Basque communities rallied behind her leadership. Off the court, Díez spearheaded the club's youth outreach programs, running free handball clinics for girls aged 8 to 14 across the Basque Country, and advocated for equal pay and improved training resources for female players at the regional and national level. In her recent interview, Díez emphasized that her attachment to Gernika KESB goes far beyond on-court achievements. "This club isn't just a team, it's a family. I still keep in touch with almost every teammate I played with during those years, and the memories we made - late-night bus rides to away matches, celebrating promotion in the town square with hundreds of fans, even picking each other up after tough losses - are worth more than any trophy I could have won," she shared. She also noted that her experience as captain shaped her current career as a youth handball coach, where she passes on the team-first values she learned at Gernika KESB to the next generation of female players. Gernika KESB's official statement responding to Díez's comments recognized her as one of the most transformative figures in the club's history, noting that her leadership laid the foundation for the team's continued success in the top Spanish league today.
