Diamondbacks Acquire 8-Time All-Star Nolan Arenado in Trade with Cardinals

The Arizona Diamondbacks acquired 8-time All-Star third baseman Nolan Arenado, 34, from the Cardinals. St. Louis sent $31 million, covering most of his remaining $42 million contract over two seasons, in exchange for minor league RHP Jack Martinez. Arenado, a 10-time Gold Glove winner, waived his no-trade clause. Despite an offensive decline in 2025 (.237 BA, 12 HR, 52 RBI in 107 games) and a shoulder issue, he finished healthy and will take over at third base for Arizona. This ends a year-long trade saga for Arenado.
