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.

The Washington Nationals, in a hypothetical redraft of the 2020 MLB draft, would have chosen Canadian outfielder Owen Caissie instead of their original pick, pitcher Cade Cavalli. Caissie, who was selected by the San Diego Padres that year, has emerged as a top prospect, currently rated No. 2 in the Chicago Cubs' farm system and No. 34 overall in baseball. His impressive Minor League performance includes a .278 batting average, 19 home runs, and 11 stolen bases in 2024.

On the other hand, Cavalli, who debuted in 2022, has struggled with injuries, including Tommy John surgery that sidelined him for most of 2023 and 2024. Despite a promising minor league career with a 3.46 ERA and 11.5 K/9 rate, he faces challenges in command and the need to maintain health as he aims to secure a spot in the Nationals' rotation in 2025.
