The 2025 MLB season has seen some highly regarded rookies struggle to meet expectations, as highlighted by the performances of Roki Sasaki, Dylan Crews, Kristian Campbell, Cam Smith, and Matt Shaw. These players were once top prospects, yet have had disappointing starts in the majors. While Sasaki has faced injury issues and a troubling transition with a 4.72 ERA, Crews has seen his batting average dip below .200. Campbell started strong but has since faced a steep decline, while Smith's and Shaw's performances have been inconsistent, leaving fantasy owners disheartened. The hype surrounding rookie prospects can often overshadow the challenges they face in adapting to the big leagues.
