​Who can be stashed in fantasy baseball for high returns? The answer lies with incoming prospects, those players nearing their major league debuts as the season progresses. This is the time of year when the sport’s top prospects trend toward the majors, and identifying the best stash targets can pay off handsomely in dynasty formats. Here are several prospects who stand out as strong stash options, particularly for long-term rosters.
De Vries sits at No. 2 in Baseball America’s prospect rankings. He’s currently in Double-A, but he’s positioned for a call-up soon with an ETA around 2026. Offense isn’t an issue for him; he’s posting a .278 batting average with a .797 OPS and 10 home runs. The 19-year-old shortstop displays a well-rounded game and projects to contribute across multiple categories. His 2026 numbers in Double-A Midland represent his best season yet, and even if he isn’t promoted in 2026, he remains a plausible contributor at the major league level in 2027.
Anderson, ranked No. 5 among baseball prospects, is another high-upside name to consider. There’s some uncertainty about an imminent promotion from the Mariners, but his upside is undeniable. If he isn’t called up by the end of the season, a 2027 debut seems likely. In 2026, Anderson posted a 1.36 ERA in Double-A Arkansas with an impressive 13.4 strikeouts per nine innings and has earned his share of accolades for his performance and polish.
Clark appears poised for a call-up this season, with timing the only variable. The MLB ranks him as the 13th-best prospect, age 21, with a 2026 ETA. Clark has toiled in Triple-A Toledo, where he’s slashed .268 with a .754 OPS, and his standout asset is elite speed, evidenced by 20 stolen bases. As a high-volume base stealer, Clark could provide immediate value once given a chance in the Tigers’ outfield, potentially filling in for the current center fielder, James Outman, if the opportunity arises.
Jenkins is the Twins’ No. 14 prospect and has already seen a recent promotion to Triple-A after a strong start in Triple-A and a solid stretch in the majors. In his most recent stint with the team, he’s slashed .281/.381/.829 across 37 games at the Triple-A level, and his MiLB 2026 line of .310/.905 is indicative of his plate discipline and power. With no glaring weaknesses, Jenkins could be promoted soon to replace current right fielder option, potentially earning opportunities in the near term.
Velasquez, a 21-year-old former first-round pick, has delivered 2026 results that catch the eye. Through a split Double-A/Triple-A season, he’s hitting .294 with an .879 OPS and shows above-average raw power (60 rating in scouting reports). He’s averaging roughly one home run every seven games and presents a legitimate power threat that could translate into fantasy value with a big league call-up.
Arroyo has already earned a Triple-A promotion, having recently logged his first games there after a successful Double-A run that saw him hit .287 with an .820 OPS. In his first taste of Triple-A Tacoma, he’s batting .333 with a 1.178 OPS over 18 at-bats as of July 10, signaling his readiness for a bigger stage. He’s in good form and appears primed for a call-up, though some teams may still weigh their in-season needs before promoting him.
Cole Young remains a notable development arm in the Mariners’ system. While his path to the majors might hinge on roster decisions and the performance of others, he is a high-ceiling prospect whose progress deserves monitoring as the season unfolds.
On the other hand, the Rockies appear close to bringing up Condon. His 2026 Triple-A campaign has been explosive, featuring a .286 batting average, a .998 OPS, and 20 home runs, underscoring his potential as a powerful contributor in the upper levels and possibly the majors in the near term.
In sum, the group above offers a mix of floor and ceiling that makes them strong stash targets for dynasty formats. They carry varying timelines for impact, from likely immediate call-ups to projections for 2027 and beyond. When building a deep-league roster or looking to capitalize on long-term value, these prospects give fantasy managers a strategic set of options to consider for high-return stashes.
