Identifying key injured players and promising prospects is crucial in the late fantasy baseball season. Shane Bieber's imminent return from injury is highly anticipated as he has dominated in rehab outings, striking out seven in five innings. He is currently owned in 40% of leagues and is recommended as a must-add for teams looking to bolster their pitching. Spencer Arrighetti of the Houston Astros, another potential fantasy gem, is expected to join the roster soon after a solid rehab stint, with only 33% ownership. Bryce Miller of the Seattle Mariners, despite struggling early this season, could provide value upon his return if he regains form. Other notable mentions include Luis Heel of the New York Yankees and Nestor Cortez, both of whom are also making their way back from injuries.
