As the 2025 MLB season opens, several players have emerged as spring training standouts and potential fantasy gems. Gavin Williams of the Cleveland Guardians, previously hindered by elbow issues, has regained his elite fastball and is being touted as a dark horse Cy Young candidate with an ADP rising significantly this spring. Houston Astros' prospect Cam Smith is another name to watch after impressing in camp, earning a spot in the opening day lineup despite limited professional experience. In the Braves rotation, Grant Holmes has shown notable improvement and control, making him a solid late-round pick. Meanwhile, Christian Yelich's return from back surgery raises questions about his previous MVP-level production, though signs of power have re-emerged. Among the rookie contenders, Jackson Jobe and Victor Scott II have both made strong impressions, with Scott set to be the opening day center fielder for the Cardinals. However, concerns loom over players like Shane McClanahan and Rafael Devers, both dealing with health issues that could impact their fantasy value this season.
