The St. Louis Cardinals could be days away from trading a franchise cornerstone away. Recently, it has seemed unlikely that Nolan Arenado would be traded this summer thanks in large part to his no-trade clause and the club’s early success this season.

In the outfield, the Rockies had Charlie Blackmon (29 homers, .860 OPS) and Carlos Gonzalez (16 homers, .796 OPS), as well as veteran Gerardo Parra (six homers, .714 OPS). Parra, along with CarGo, brought some levity to an otherwise all-business clubhouse.

Less than a week from the MLB trade deadline, the St. Louis Cardinals are poised to be sellers. While Ryan Helsley, Phil Maton, and Steven Matz are the obvious trade candidates, there's another player to monitor: Nolan Arenado.
