As the 2025 MLB season races toward the playoffs, savvy dynasty baseball managers are already planning for 2026. Especially if they are already out of the picture this season. Managers stashing young prospects or buying low on undervalued players with breakout potential can transform your roster from pretender to contender in the blink of an eye. Late-season call-ups have already begun to set in for teams that are out of the playoff race, and now is the time to grab these 6 Dynasty Stashes before they make a name for themselves and see their stock skyrocket.
Backed by recent performances, advanced metrics, and favorable team situations, these are the names to secure before your leaguemates catch on.
1. Luke Keaschall, Minnesota Twins (OF/IF) Age 23
Why He’s a Stash: he has been turning heads since returning from an early-season injury. His recent call-up and multi-position eligibility (2B, CF) make him a versatile option. In the minors, he posted a .305/.400/.490 (AVG/OBP/SLG) slash line with 10 HRs and 15 SBs in 80 games, showcasing his rare power-speed combo. The Twins are in the AL wild-card hunt, and Keaschall could see expanded playing time in September, especially with the departure of shortstop Carlos Correa at the trade deadline.
2026 Outlook: his contact ability (15% K-rate) and speed make him a potential .280/15 HR/20 SB player in a full MLB season. His rostership is <10% on ESPN, which makes him a dirt-cheap stash for next season.
2. Dylan Beavers, Baltimore Orioles (OF) Age 24
Why He’s a Buy-Low: Beavers has been recently called up, and it has flown under the radar despite being ranked among the top 300 in ESPN’s rest-of-season projections. His minor league stats (.290/.380/.510) with 18 HRs and 20 SBs scream five-tool player. Baltimore is fighting for the AL East crown, which is leaving Beavers with limited chances in a crowded outfield, but when his time comes, he will be a fantasy stud. His limited playing time is also serving to suppress his fantasy value.
2026 Outlook: Beavers plays in a hitter-friendly Camden Yards and could emerge as a 20 HR/15 SB outfielder with a .270 AVG. His talent level and pedigree suggest he is due for positive regression after a slow start in his limited time, and smart managers should attempt to acquire him while his stock is low and before he becomes an everyday starter next season.
3. Bubba Chandler, Pittsburgh Pirates (SP) Age 23
Why He’s a Stash: Chandler has surged onto the fantasy radar with a 2.80 ERA and 11.5 K/9 in his most recent MLB starts. His electric fastball-slider combo makes him a strikeout machine, and Pittsburgh’s rebuilding phase ensures he’ll get a long leash in 2026. He is currently rostered in <15% of ESPN leagues and is a prime waiver pickup.
2026 Outlook: he projects as a middle-of-the-rotation starter with 180+ strikeouts and a sub-3.50 ERA. His youth and limited innings in 2025 make him a low-risk, high-reward stash for dynasty leagues.
4. Jasson Dominguez, New York Yankees (OF) Age 22
Why He’s a Buy-Low: Despite years of hype, Dominguez’s ADP remains incredibly low (outside the top 150 on ESPN) due to a crowded Yankees outfield. His slow recovery from Tommy John surgery is also helping to keep him affordable. He had a brief MLB stint in 2024 (4 HRs in 8 games) and showed off elite power and speed. His 2025 minor league numbers (.280/.350/.480) suggest he is ready for a full-time role with the big club.
2026 Outlook: Dominguez could be a 25 HR/20 SB player hitting at Yankee Stadium. His current.240 AVG in limited action makes him a buy-low target before he breaks out. Expect him to be an Opening Day starter for New York in 2026. Cody Bellinger is expected to exercise his player option in the offseason and test free agency.
5. Triston Casas, Boston Red Sox (1B) Age 25
Why He’s a Buy-Low: Casas is a former top prospect, but has disappointed fantasy managers with a .182 AVG and 3 HRs in 2025. However, his .580 OPS and cleanup role in Boston’s lineup scream upside. His current ADP (117 on ESPN) is far too low for a 25-year-old with his talent and plate discipline (12% BB rate) and power potential. He is currently rehabbing from a ruptured patellar tendon, which has taken him off the fantasy radar. A full return to form should be for next season.
2026 Outlook: He could easily hit .270 with 30 HRs and 90 RBIs in the friendly confines of Fenway Park next season. His current stats indicate he’s been unlucky, making him a prime buy-low candidate.
6. Jakob Marsee, Miami Marlins (OF) Age 24
Why He’s a Stash: Acquired by the Marlins at the trade deadline, Marsee’s speed (30 SBs in the minors) and on-base skills (.380 OBP) make him a sneaky stash. His recent MLB debut has reignited hope. He is currently hitting .383, and Miami’s rebuilding roster guarantees him playing time in September and beyond. He is rostered in <5% of ESPN leagues and is a deep-league gem.
2026 Outlook: Marsee projects as a .260 hitter with 10 HRs and 30+ SBs. His skill set is perfect for roto leagues that emphasize speed. His role in Miami’s outfield should solidify in 2026, with little competition on the roster.
