Week 20 in 2025 fantasy baseball tightens the rookies’ clock as teams push promotions while preserving rookie eligibility for 2026. The wave includes Spencer Jones, Andrew Painter, Dylan Beavers, Kristian Campbell, Samuel Basallo, and Luke Keaschall as top redraft stash candidates who could spark immediate value or set up big-season potential. Jones offers multi-position upside and power, Painter could anchor PHI’s rotation, and Beavers provides speed and pop. Campbell’s hot stretch plus Basallo’s elite power add high-upside depth, while Keaschall’s speed and approach profile keep him on the radar for late-season callups. These shooters-in-waiting shape rosters and bets through the rest of 2025 and beyond.

Promotions are starting to cluster as the calendar turns, with recent callups and near-promotions signaling a broader path to the majors in the final weeks. The piece flags notable names already promoted last week and discusses how rookies in Triple-A are balancing upside with rookie-year eligibility rules. Fantasy managers should consider stashing these players in redraft formats for Week 20 and beyond, balancing upside with the timing risk of late-season debuts and the long-term implications for 2026 eligibility.
