Week 22 of fantasy baseball centers on fresh MLB call-ups who can contribute in the final sprint. Samuel Basallo, Dylan Beavers, Carson Williams, and Jhostynxon Garcia joined the big leagues this past week, with Bubba Chandler surfacing on the mound. JJ Wetherholt, Sal Stewart, Spencer Jones, Kristian Campbell, and Jordan Lawlar headline the list of top stash-worthy prospects poised to impact fantasy rosters down the stretch. Bryce Eldridge, Carson Benge, Justin Crawford, Moises Ballesteros, and Jonathon Long round out the stash pool, offering a mix of power, speed, and positional versatility. These rookies present varied paths to value in redraft and dynasty formats, especially for fantasy players chasing late-season surges and postseason push incentives.

Wetherholt’s potential call to help the playoff push for St. Louis sits against a backdrop of strong minors numbers across Double-A and Triple-A, including solid contact profiles and growing power. Stewart’s hit tool and multi-position upside in Cincinnati adds immediate fantasy floor, particularly in deeper formats with mixed batting stats. Spencer Jones brings massive power with OBP-friendly upside in Yankee-land, while Campbell and Lawlar offer infield flexibility and speed in Boston and Arizona, respectively. The quartet of Eldridge, Benge, Crawford, Ballesteros, and Long adds a blend of raw power and development trajectories that could unlock Week 22 bench value in NL- and AL-led rosters. Overall, Week 22 emphasizes high-ceiling, roster-stashing moves for season-end impact and potential playoff leverage.

Week 21 fantasy baseball focuses on 2025 redraft value from a curated top-25 stash list. Prospect call-ups that debut this year preserve rookie eligibility for 2026, broadening short- and long-term value. Promoted last week: Dylan Beavers, Samuel Basallo, Drew Gilbert, Nolan McLean and Owen Caissie, with Eldridge and Sal Stewart standing out for immediate impact in power and solid hitting floors. The piece highlights Spencer Jones’s sky-high upside despite strikeout risk, JJ Wetherholt’s Triple-A dominance, and Robby Snelling’s near‑MLB-ready pitcher profile.

Analysis dives into Bryce Eldridge’s likely Giants cup of coffee, Sal Stewart’s advanced hit tool, and Wetherholt’s polished approach at the plate. It maps out why these names belong on rosters in 2025 redraft and how late-season call-ups could shape Week 21 lineups. Honorable mentions add depth across teams, while the feature ties in DFS and lineup tools to sharpen Week 21 decisions.

Samuel Basallo, Nolan McLean, and J.J. Wetherholt stand out as the most intriguing fantasy baseball risers on the spring-to-summer radar. Basallo, Baltimore’s 21-year-old catcher, is in the majors after a monster Triple-A run, slashing 270/377/589 with 23 homers in 76 games and elite exit velocity. With catcher eligibility and regular playing time at first base/DH, his power upside makes him a prime stash in 12+ team leagues.

Nolan McLean of the Mets carved out a spot after Frankie Montas moved to the bullpen, delivering a solid late-start debut and a line that mirrors his AAA season: 2.45 ERA with a 27% strikeout rate over 113.2 innings. If his control holds, his mid-rotation upside could keep him in the rotation beyond a spot start or two, offering valuable fantasy value when he’s stretched out.

J.J. Wetherholt, the Cardinals' shortstop prospect, is tearing through Triple-A with a .310/.403/.670 line and 9 homers in limited action, plus a standout exit velocity profile. A September cup of coffee could come this year, with a real chance to step into a part-time role and push for Rookie of the Year potential in 2026. All three are worth rostering in 12+ team leagues and could become central pieces down the stretch.

Samuel Basallo’s lifelong dream became reality when the Orioles promoted the 21-year-old slugger from Triple-A Norfolk to the majors. Basallo, widely regarded as baseball’s top catching prospect, posted 23 homers in 76 games at Norfolk this season and drew praise from teammates and management for his bat-driven ceiling. His arrival, paired with Dylan Beavers’ debut a day earlier, signals Baltimore’s aggressive push for impact talent at the MLB level while protecting rookie eligibility for 2026 by promoting them after Aug. 15.

The kid-glove arrival featured Basallo batting sixth as the DH in his first big-league game, taking a pitch in his first at-bat, grounding into a double play, getting robbed of a three-run shot, and ultimately delivering a two-run single for his first MLB hit. Beavers followed suit with his own major-league introduction, marking a rare back-to-back rookie debuts for Baltimore at the deadline-spurred reshuffle.

Baltimore’s move centers on long-term rookie eligibility leverage: promote Basallo and Beavers after August to preserve rookie status for 2026, a move that could yield a 2027 first-round draft pick if either wins AL Rookie of the Year. Orioles interim skipper Tony Mansolino lauded Basallo and Beavers for earning their spots, while Basallo credited his Norfolk roommate Beavers for helping him navigate a grinding, triumph-filled summer. The backing of the organization underscores a Latin American development push led by Mike Elias and Koby Perez, with Basallo representing a pinnacle moment after their international investment.
