Week 21 stash targets lean heavily Orioles and Reds, with Basallo and Beavers leading the charge for immediate power and speed as rosters expand post-deadline. Basallo’s Triple-A numbers pop: 23 homers, 154 WRC+, and a scorching 93.9 MPH exit velocity, plus catcher eligibility that boosts fantasy flexibility. Beavers has been quietly productive with a 152 WRC+, 18 HR, and 22 SB across the minors, offering a balanced power-speed profile ready for a call-up. Campbell, Crawford, and Stewart bring mid- to late-season punch—Campbell heating up in Triple-A, Crawford flashing elite sprint speed, and Stewart showing a mature bat with growing power. Reds’ Elly De La Cruz looms as a surrounding impact piece, while Mullins, Laureano, Hayes and Duran provide veteran context for how drastic a call-up window can feel.

Call-up windows are the narrative here: teams may roll prospects while keeping them prospect-eligible, and Week 21 could deliver a flood of juice for fantasy stretch runs. The piece keeps a practical eye on lineup tools, BvP/PvB data, closer depth, injuries, and live scoring—tools every fantasy manager will lean on as these rookies surface. In short, stash power with Basallo and speed with Crawford and Beavers, while watching Sal Stewart and Campbell for breakout timing in the Reds and Red Sox pipelines. Kept expectations lean toward immediate contribution in fantasy formats that value multi-category impact and speed power blends.
