The St. Louis Cardinals have turned their attention to their top prospects after a disappointing season, and JJ Wetherholt is poised to be their breakout star in 2026. Wetherholt, the organization's top prospect, is expected to make the opening day roster, start at second base, and compete for the National League Rookie of the Year award.

Why it matters

The Cardinals are undergoing a major rebuild, and Wetherholt's success could be a key part of their future plans. As one of the best young talents in baseball, his development will be closely watched by the organization and fans alike.
