Arenado has two years remaining on his deal after 2025, making his choice one of baseball’s most substantial decisions this July.

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.

There are two reasons why a trade might be difficult to execute for the Cardinals. The first is Arenado's full no-trade clause. In the offseason, he used it to veto a deal with the Houston Astros. That could scare some teams away from trying to trade for the Cardinals' third baseman.
