Agustín Sienra (born 14 July 1999) is an Argentine professional footballer who plays as a centre-back for Spanish club CD Castellón.[3]

Career

Sienra started off his career with Defensores Santa Catalina, before later signing with Newell's Old Boys.[4][5][6] In 2016, following a trial, Sienra joined the youth system of Defensa y Justicia.[5][2] He made the move into first-team football towards the back end of 2020, appearing as an unused substitute for Copa Libertadores matches with Delfín (twice) and Olimpia and a Copa de la Liga Profesional encounter with Colón between September and November.[3][7] It was in the latter month that the centre-back made his senior debut, as he featured for seventy-nine minutes of a domestic defeat to Central Córdoba on 29 November.[3]

On 5 August 2021, Sienra was loaned to Villa San Carlos until December 2022.[8] On 5 January 2023, he moved to San Martín de San Juan also in a temporary deal.[9]

Sienra helped San Martín to achieve promotion to the top tier in 2024,[10] before returning to Defensa for the 2025 season.[11] On 7 July of that year, after just three further first team appearances, he moved abroad and signed a one-year deal with Spanish Segunda División side Castellón.[12]
