The 2025 MLB season is heating up as Week 18 approaches, and it’s time to look at the top fantasy baseball prospects to stash. Key players like Carter Jensen from the Kansas City Royals is showing great promise with a significant improvement in his batting average and power numbers. As a catcher, his ability to not only hit but also manage the game behind the plate makes him a strategic stash for your team. Spencer Jones of the New York Yankees is making headlines with explosive performances, including multiple home runs and impressive exit velocities, suggesting he could soon be a fixture in the Bronx. Similarly, Brandon Sproat of the New York Mets is on a roll, showcasing an uptick in velocity and strikeout capabilities, positioning him as a potential call-up. Andrew Painter from the Philadelphia Phillies is also in the mix, with a chance to impact a playoff push despite some inconsistency. These players could be the key to your success as we inch closer to the season's peak.
