- Kade Anderson (Mariners SP) has posted a 1.06 ERA with 135 strikeouts in 93⅓ minor-league innings and is rostered in 73% of CBS leagues, with the writer noting Bryce Miller's recent struggles make a six-man rotation unnecessary.
- Walker Jenkins (Twins OF) reached Triple-A at age 21 with a .309 BA and .908 OPS this year, and the source argues his on-base skills alone could swing Minnesota's playoff push, where they sit a half-game up on the third AL wild card.
- Ralphy Velazquez (Guardians 1B) has hit 11 homers in his past 16 games at Triple-A, and the source notes he's one of the few first-base prospects on all top-100 lists despite being excluded from the writer's earlier list of 15 call-up candidates.
- Ethan Salas (Padres C) has batted .297 with 10 HR and 15 SB in the minors and made contact on 99% of his swings in the strike zone since moving to Triple-A, where Luis Campusano's defensive shortcomings have him out of the lineup half the time.
- Quinn Mathews (Cardinals SP) has already made two major-league spot starts and cut his walk rate to 4.5 per nine innings over his last 13 outings, offering fantasy value at the most turnover-heavy position.
- Xavier Isaac (Rays 1B) revealed this offseason that a brain tumor caused the extreme fatigue behind his .2025 BA dip, and has slashed .331/.468/.653 over his past 34 games while dropping his strikeout rate from 24% in May to 13% in August.
- Only one prospect — Joshua Baez — has debuted so far in the final-stretch window, becoming the first player to homer three times in his major-league debut, with the bulk of remaining notable call-ups expected within the next two weeks.
Why it matters: For fantasy players, the 45-day window is the last chance to stash 2026 rookies before they burn eligibility for next season, and the source identifies concrete breakout stats — Anderson's 1.06 ERA, Velazquez's 11 homers in 16 games, Isaac's post-tumor renaissance — that materially shift stash priorities on contending teams' rosters.
