Injuries are shaking up the fantasy baseball landscape as the 2025 MLB season rolls into its fourth week. Spencer Strider of the Atlanta Braves, Colton Cowser, and Grayson Rodriguez of the Baltimore Orioles are each facing significant setbacks, affecting their fantasy value. Strider, who underwent an offseason procedure, is now sidelined again with a Grade 1 hamstring strain. The Braves expect his absence to be brief, possibly returning in early May. Meanwhile, Cowser's thumb fracture incurred just four games into the season will keep him out until late May or early June, but his potential impact upon return remains high. Rodriguez, having dealt with both elbow inflammation and a mild lat strain, might not be back until around the All-Star break. For fantasy managers, managing these injuries effectively is crucial for navigating the upcoming summer months.
