The St. Louis Cardinals could trade struggling third baseman Nolan Arenado and closer Ryan Helsley to the Toronto Blue Jays, offering a potential midseason shake-up ahead of the MLB trade deadline.

However, Arenado's perspective on a move to Houston could change. The Astros hold the lead in the AL West, while the Cardinals continue to fight to stay in playoff contention in the National League. St. Louis is 3.5 games behind the San Diego Padres for the last Wild Card spot.

The Astros are again talking to the Cardinals about a Nolan Arenado trade, but the two sides aren't close to a deal.
