The St. Louis Cardinals are expected to be quite active ahead of the trade deadline this season, but nobody really knows what their approach is going to be. The Cardinals have some trade chips they could deal away, but there are also some glaring holes to fill on the roster. St. Louis could find themselves on the fence, which might push them toward selling some expiring players while buying on the controllable talent on the trade block. ESPN’s Jeff Passan and Kiley McDaniel recently listed the Cardinals as one of the “best fits” in a massive trade for Milwaukee Brewers ace Freddy Peralta.
