The St. Louis Cardinals and Boston Red Sox are actively engaged in discussions regarding potential trades, with Nolan Arenado initially considered as a target for the Red Sox. However, after Boston signed Alex Bregman, the likelihood of Arenado joining Boston appears slim. Instead, a hypothetical trade proposed by FanSided's Zach Pressnell involves the Red Sox acquiring pitchers Ryan Helsley and Erick Fedde, while sending first baseman Triston Casas to the Cardinals. Helsley, who led the league in saves last season, could fit seamlessly into Boston's bullpen, potentially replacing Kenley Jansen. Meanwhile, Fedde would bolster the Red Sox rotation, which is in need of experienced depth due to current injuries. While trading Casas has been a topic of speculation, this proposed deal remains theoretical at this stage.
