The top prospect in the Texas Rangers organization is Sebastian Walcott, and there’s not really any debate about that. Walcott seemed to be a consensus top 20 guy heading into the 2025 season, and he has climbed the ranks in the updates this month. In their latest update, Baseball America has Walcott as the #7 prospect overall,* and Kiley McDaniel has Walcott ranked #4 overall in his update earlier this week.
* Roki Sasaki and Jackson Jobe are still on the BA list, while McDaniel has removed them from consideration for his list, so you can consider Walcott #5 instead of #7 on BA’s list if you want.
