Baltasar Luis Gallego Rodríguez (born 9 July 2003) is an Argentine footballer who plays as a midfielder for Inter Miami CF, on loan from Racing Club de Avellaneda. Born in Monte Hermoso in Buenos Aires Province, Rodríguez joined the youth ranks of Racing Club de Avellaneda from his hometown club in 2019. His agent is Robert Pires, 1998 FIFA World Cup champion with the France national football team. In August 2022, Rodríguez signed his first professional contract to tie himself to Racing until the end of 2026, with a release clause of €20 million. He made his debut in the Argentine Primera División on 8 May 2023 in a 4–2 home loss to Talleres de Córdoba; he came on as a 55th-minute substitute for Gabriel Hauche and became the first top-flight player from his town. His continental bow came on 8 June in a 2–1 Copa Libertadores group loss to Flamengo in the Maracanã Stadium. On 19 August he started the game away to Unión de Santa Fe and scored his first goal to open a 1–1 draw for the club managed by Fernando Gago. He finished his first season with five goals. On 20 August 2024, Rodríguez scored his first continental goal to start a 6–1 win over Chile's Huachipato FC at El Cilindro, putting his side into the quarter-finals of the Copa Sudamericana 8–1 on aggregate. His team won the final 3–1 over Brazil's Cruzeiro in Asunción, though he was an unused substitute. After winning the 2025 Recopa Sudamericana with Racing over Botafogo, Rodríguez moved to Major League Soccer club Inter Miami CF on loan. He was signed by Javier Mascherano, his former Argentina U-23 manager. He made his debut on 14 May as a half-time substitute for Benjamin Cremaschi, and assisted the equaliser by compatriot Tadeo Allende in a 3–3 draw away to the San Jose Earthquakes.
