Nolan Arenado, a potential Hall of Fame third baseman, has reportedly blocked a trade from the St. Louis Cardinals to the Houston Astros, a significant rival of the Seattle Mariners. Despite the Astros' recent success, Arenado's decision not to waive his no-trade clause raises questions about his confidence in their future.

Having spent eight successful years with the Colorado Rockies, Arenado has made a name for himself with multiple All-Star selections and Gold Glove Awards. However, his recent performance has shown signs of decline, and winning a World Series seems to be a priority for him in any trade considerations.
