As we approach Week 9 of the 2025 MLB season, identifying key prospects to stash in your fantasy league is crucial. Ryan Ritter of the Colorado Rockies is having an exceptional minor league season, amassing an 11-game hitting streak, showcasing a blend of power and speed. Jacob Misiorowski's impressive 0.96 ERA with a 35% strikeout rate for the Milwaukee Brewers indicates he's ready for a big league call-up. Meanwhile, Jac Caglianone continues to hit well for the Kansas City Royals, making a strong case for promotion with 14 home runs between Double-A and Triple-A.

Cade Cavalli's recent form suggests he could contribute soon to the Washington Nationals, boasting a 1.29 ERA over his last three starts. These players represent not just potential but the chance to gain a significant edge in your fantasy league with timely promotions.
