The St. Louis Cardinals face a narrowing trade market for star third baseman Nolan Arenado, with the Boston Red Sox emerging as the sole team interested in acquiring him before the 2025 season. According to reports, the Red Sox are also looking to sign free-agent Alex Bregman, which could influence their pursuit of Arenado. If Boston fails to sign Bregman, they may consider trading for Arenado, but this would likely involve moving Rafael Devers to first base and potentially trading Triston Casas.

Arenado, a ten-time Gold Glove winner and eight-time All-Star, had a solid 2024 season, playing 152 games with a .272 batting average, 16 home runs, and 71 RBIs. His desire for a World Series title complicates his situation, as the Cardinals have missed the playoffs for two consecutive years. Meanwhile, the Red Sox have not reached the postseason in three years and are looking to strengthen their roster after recently acquiring Garrett Crochet and signing pitchers Walker Buehler and Patrick Sandoval.
