Logan Henderson, SP, Milwaukee Brewers

Current Level: Triple-A

Milwaukee Brewers pitching prospect Logan Henderson should be a name for fantasy managers to keep an eye on in the early going of the 2026 season. Although the right-hander was optioned to Triple-A earlier this month, he'll surely be one of the first names considered when Milwaukee needs pitching help.

The former fourth-round draft pick debuted last year with good results, posting a 1.78 ERA, 0.99 WHIP, and an elite 25.3 percent K-BB% over five starts with the big league club. The 24-year-old looked good again in limited action this spring, allowing just one earned run in six innings pitched (1.50 ERA) with a 0.50 WHIP and a 4:0 K:BB. Fantasy managers with available bench space or even an NA slot should consider stashing the Brewers' seventh-ranked prospect ahead of his eventual call-up. Henderson is available in almost 80 percent of Yahoo! leagues.

Jonah Tong, SP, New York Mets

Current Level: Triple-A

New York Mets pitching prospect Jonah Tong could be an early-season call-up for the team whenever they find themselves in need of pitching. Although the right-hander struggled to a 7.71 ERA, 1.77 WHIP, and a 14.9 percent K-BB% in his five starts with the Mets last year, he was one of the most dominant arms in the minors before that.

Despite being in the majors for the final month, the former seventh-round draft pick still led all minor leaguers with 179 strikeouts in just 113 2/3 innings pitched, good for a 14.17 K/9. If he can continue to dominate to begin the 2026 campaign and perhaps tone down the walks (career rate of 11.5 percent) then he should be in contention for an early-season call-up. Pitching-needy managers in deeper leagues could consider stashing the 22-year-old, who is available in over 90 percent of Yahoo! leagues.

Konnor Griffin, SS, Pittsburgh Pirates

Current Level: Triple-A

It was announced on Saturday that Pittsburgh Pirates shortstop prospect Konnor Griffin would not be on the team's Opening Day roster, and on Sunday, Milb Central reports that Griffin will start the year at Triple-A Indianapolis. It was looking like the 19-year-old phenom might become the first teenager to start on Opening Day since Ken Griffey Jr. did it back in 1989.

He hit just .171 (7-for-41) in 16 Grapefruit League games, but Griffin also had four home runs, nine RBI, a stolen base, five runs scored, and a .749 OPS this spring. The former ninth overall pick in 2024 impressed his teammates with his physicality and his maturity in spring training. In three minor-league levels in 2025, Griffin excelled with a .333/.415/.527 slash line, .941 OPS, 21 home runs, 94 RBI, 117 runs scored, and 65 stolen bases in 122 games played.

Griffin can do it all on the diamond and should be up in Pittsburgh for his major-league debut sooner than later in 2026. Even though he'll start in the minors, fantasy managers should be stashing the potential once-in-a-generation talent.

Robby Snelling, SP, Miami Marlins

Current Level: Triple-A

Miami Marlins pitching prospect Robby Snelling did not earn a spot in the team's starting rotation to begin the season, but will likely be one of the first names called when Miami needs pitching reinforcements. The Marlins' second-ranked prospect made the top two levels of the minors look easy in 2025, recording a 2.51 ERA, 1.11 WHIP, and a 23.2 percent K-BB% across 25 starts (136 innings pitched) between Double and Triple-A.

Despite allowing seven earned runs in 8 1/3 IP this spring, the southpaw showed his strikeout potential with 13 punchouts during that time. The 6-foot-3 hurler owns a 27.1 percent K% in 71 minor-league starts and has shown solid command, too, with an 8.0 percent BB% for his career. With the 22-year-old standing on the doorstep to the big leagues, the 39th-overall selection in the 2022 Draft is one of the top pitching stashes for fantasy, and is available in over 90 percent of Yahoo! leagues.

Bryce Eldridge, 1B, San Francisco Giants

Current Level: Triple-A

San Francisco Giants first base prospect Bryce Eldridge should remain on the fantasy radar in the early part of 2026, as the Giants' top-ranked prospect has some of the biggest power potential in the minors. The 6-foot-7 slugger blasted 25 home runs between Double-A and Triple-A last year in just 100 games, and although he was left off the club's Opening Day roster, he'll likely be back in the majors sometime in the first half of the season.

The left-handed slugger carries some batting average risk with the amount of swing-and-miss that comes with his power stroke, but managers who are looking for a home-run boost should keep the former first-round draft pick top of mind, and he should be a top stash candidate in deeper leagues as the regular season gets underway.

Bryce Eldridge, oppo strength 💪

Harry Ford, C, Washington Nationals

Current Level: Triple-A

Washington Nationals catching prospect Harry Ford was optioned to Triple-A Rochester earlier this month after an underwhelming spring, but that doesn't mean he won't be back in the big leagues soon. The Nats' third-ranked prospect is a former 12th-overall draft pick and had a strong 2025 at Triple-A, hitting .283 with 16 home runs while walking (74) nearly as many times as he struck out (88), which earned him a late-season promotion with the Mariners.

The former first-rounder has a solid contact/power blend with his bat, and with his ability to draw walks, there is a solid OBP floor. The catcher's position is one of wear and tear, so there could be an opening for him on the major league roster sooner rather than later, and the 23-year-old should be considered one of the top stash candidates in deep two-catcher leagues.

Kaelen Culpepper, INF, Minnesota Twins

Current Level: Triple-A

Minnesota Twins top infield prospect Kaelen Culpepper is set to begin the 2026 regular season with Triple-A St. Paul. Culpepper will open the campaign just one step away from the major leagues, which will set him up for an early 2026 debut. Culpepper joined the Twins as the 21st overall selection in the 2024 Draft out of Kansas State. Last summer, Culpepper split his time between High-A and Double-A.

At High-A, the infielder carried a .293/.385/.479 line with nine home runs and 15 stolen bases. At Double-A, the 23-year-old took a slight step down, carrying a .285/.267/.460 slash line with 11 home runs and 10 stolen bases. If Culpepper continues this trajectory with St. Paul, he should join Minnesota before the All-Star break. He is worth monitoring in deeper formats for now and could emerge as an early-season top stash candidate.
