As the 2025 MLB season progresses, fantasy managers should be on the lookout for promising prospects to stash on their rosters. This week's top five includes Bubba Chandler and Cade Horton, both of whom are poised for major league debuts soon. Chandler, a starting pitcher for the Pittsburgh Pirates, boasts impressive minor league stats, including a 2.25 ERA and 41 strikeouts. Meanwhile, Chicago Cubs' Horton has a stellar 1.24 ERA at Triple-A and will be stepping into the rotation due to an injury to Shota Imanaga. Other noteworthy prospects include Jacob Misiorowski of the Milwaukee Brewers, Andrew Painter of the Philadelphia Phillies, and Moises Ballesteros of the Cubs, who is excelling offensively despite facing a crowded depth chart.
