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.

Arizona Diamondbacks top infield prospect Jordan Lawlar is nearing a big league return as the team moved Eugenio Suárez at the trade deadline, clearing a path for extended playing time. Lawlar has dealt with a hamstring injury but is cleared to take live batting practice and could be activated from the 7-day IL in the coming weeks, weather permitting. His Triple-A Reno numbers have been elite, underscoring a high ceiling once promoted. In his first MLB stint, Lawlar showed a small sample with limited at bats, but the leash should be longer if Arizona commits to him as a regular in the wake of Suárez’s departure.

Lawlar is viewed as a five-category upside player who can contribute across speed, power, average and runs with strong plate discipline. Fantasy managers should consider stashing him in 12+ team leagues as Week 20 approaches, especially with the clear path to at-bats once he is recalled. The latest prospect rankings place him among the top impact names, and the combination of his speed and power makes him a natural late-season catalyst if he secures daily at bats.

Fantasy baseball managers are always on the lookout for emerging talent, and this week's spotlight shines on three notable prospects: Justin Crawford, Jordan Lawlar, and Jonah Tong. Each player is making waves in the minors and could significantly impact your fantasy roster.

Justin Crawford, an outfielder with the Philadelphia Phillies, boasts a stellar .325 batting average and outstanding speed with 33 stolen bases this season at Triple-A. His lack of power, reflected by only three home runs, may push him down the rankings, but his ability to steal bases and get on base should warrant serious consideration for stashing.

Jordan Lawlar of the Arizona Diamondbacks is another player to watch. With a .319 average, 10 home runs, and 18 stolen bases, he possesses an impressive all-around skill set. He is expected to return soon from a rehab assignment and could play a critical role in Arizona's lineup, especially with a more regular opportunity looming.

Finally, Jonah Tong from the New York Mets has been dominant as a pitcher in Double-A, leading with a 1.66 ERA and an eye-popping 146 strikeouts in just 92 innings. While there may be concerns about his immediate chance of being called up, he is a must-stash in keeper and dynasty leagues.

Jordan Lawlar, J.J. Wetherholt, and Kristian Campbell are three MLB prospects creating buzz for fantasy baseball managers. Lawlar, an infielder for the Arizona Diamondbacks, has shown promise with a batting average of .319 and 18 stolen bases at Triple-A. His potential for a late-season debut could make him a valuable asset if he translates his minor league success to the majors. Meanwhile, J.J. Wetherholt of the St. Louis Cardinals is proving he’s ready for the big leagues, with impressive power and consistency at the plate, hitting .321 and showcasing an exit velocity over 90 mph. Lastly, Campbell, playing for the Boston Red Sox, has been on fire post-All-Star break, making him an intriguing option despite a rocky start earlier in the season. As the trade deadline passed with minimal action from the Red Sox, Campbell's opportunity for a call-up could materialize soon.

As the 2025 MLB season approaches, several top prospects are poised to make significant impacts for fantasy baseball managers this upcoming year. With the trade deadline having reshaped team rosters, particularly in Arizona and Baltimore, opportunities for rookie call-ups are ripe. Tyler Locklear's recent promotion to the Arizona Diamondbacks makes him a compelling add in deeper leagues. Meanwhile, teams may push for further promotions post mid-August to maintain rookie eligibility for next season, especially for talents like Dylan Beavers and Samuel Basallo.

Beavers has been a standout for the Norfolk Tides and is showcasing robust offensive metrics, including a .307 average paired with impressive power and speed. Similarly, Jordan Lawlar, now returning from injury, is set to capitalize on an open position in Arizona. His offensive prowess at Triple-A this season has been noteworthy, boasting a .319 average with power and speed. JJ Wetherholt is making waves in St. Louis, recently showcasing his offensive potential with a scorching hot streak that highlights his blend of contact, power, and speed. Other prospects like Owen Caissie and Moises Ballesteros might find themselves in contention for playing time if injuries occur among current MLB players, making them potential stashes in redraft leagues.
