The St. Louis Cardinals' recent sweep at the hands of the Arizona Diamondbacks served as a stark, undeniable signal: It's time to sell. The disappointing series underscored the team's struggles this season and should firmly place them in the "seller" category as the July 31st trade deadline rapidly approaches. With the Cardinals now in fourth place in their division and October baseball fading from view, the focus in St. Louis should be on the future, and that means maximizing returns on valuable assets.
One of the most talked-about trade pieces the Cardinals have is Ryan Helsley.
