3 Impact Fantasy Baseball Prospects To Stash - Emmanuel Rodriguez, Robby Snelling, Kaelen Culpepper

May 2, 2026

Three top fantasy baseball prospects - Emmanuel Rodriguez, Robby Snelling, Kaelen Culpepper - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.

Targeting high-end prospects is key to winning your fantasy baseball league. So far, managers have seen many rookies emerge as must-start players this season, including Parker Messick, Chase DeLauter, Noah Schultz, and potentially the recently promoted Payton Tolle.

In this piece, we will look at three prospects who are showing high upside at the Triple-A level, including two from the Minnesota Twins system.

Should fantasy managers stash these high-end prospects? Let's dive in!

Emmanuel Rodriguez, OF, Minnesota Twins

Current Level: AAA
Availability: 10% rostered
2026 AAA Stats: 22 G, .239/.409/.451, 12R, 4 HR, 3 SB

This week, we begin in St. Paul, Minnesota, home of the Twins’ Triple-A affiliate, the St. Paul Saints. Outfielder EmManuel Rodriguez has a very fantasy-friendly profile because he blends on-base ability, power, and speed. However, much like his teammate and fellow top prospect Walker Jenkins, staying on the field has been a consistent challenge. The 23-year-old left-handed hitter from the Dominican Republic has appeared in just 112 games over the past two seasons due to thumb, hip, and oblique injuries.

For fantasy, he projects to be a 25-home-run, 10-stolen-base outfielder with a high on-base percentage. Last season, Rodriguez walked 20.6% of the time, helping to balance out his 31.8% strikeout rate. He also slashed .269/.431/.409 with six home runs and 10 stolen bases across 267 plate appearances. So far this season, he has been able to stay healthy, and it's showing in his hard-hit metrics.

Earlier this month, he crushed a ball 117.1 mph, which would rank as the third hardest hit ball in MLB, sandwiched between Yordan Alvarez (117.8 mph) and Junior Caminero (116.9 mph).

In the Twins’ outfield, Minnesota currently features Trevor Larnach, Matt Wallner, and Byron Buxton, with Austin Martin as a short-side platoon option against lefties. Buxton will play as much as his health allows, but that is far from a guarantee. Meanwhile, left-handed slugger Wallner is currently struggling, slashing .186/.278/.314 with a 38.1% strikeout rate and a 68 wRC+ across 97 plate appearances.

While Wallner likely has a long leash due to his one remaining minor league option, his inability to make consistent contact could lead to an eventual demotion or reduced role. With that said, the Twins could opt to call up fellow outfielder Jenkins instead, but he’s currently struggling in Triple-A, posting a 75 wRC+ across 84 plate appearances. Historically, the Twins have been cautious with promoting corner outfield prospects, though Rodriguez could still earn a call-up by June if he stays healthy and continues to produce.

Rodriguez is worth monitoring in 15-team, five-outfielder leagues. If he is called up, he should be added immediately. In shallower leagues, however, you can take a wait-and-see approach to make sure he is worth the roster spot.

Robby Snelling, SP, Miami Marlins

Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 24 IP, 2.25 ERA, 1.04 WHIP, 35 SO, 14 BB

At this point, each passing start in Triple-A for Robby Snelling is one start too many. After posting a 1.27 ERA in 11 Triple-A starts last season, Snelling has recorded a 2.25 ERA, 1.04 WHIP, and a 37.2% strikeout rate in five starts this season. Sure, he's walked 14 batters in 24 innings, but that's not a concern for me right now as he's never experienced any notable command/control issues.

Robby Snelling had three double-digit strikeout performances in 2025 ... and now one in 2026.

Over his last three outings, Snelling has allowed just six hits and two earned runs combined in 16 innings with 25 strikeouts. Meanwhile, Chris Paddack has a 6.38 ERA and 1.54 WHIP in 24 innings as the Marlins fifth starter. It'd be easy to say that Snelling will take over for Paddack soon (and he might), but the Marlins also have Braxton Garrett waiting in the wings. Regardless, I still expect Snelling to eclipse 100 major league innings this season.

Kaelen Culpepper, INF, Minnesota Twins

Current Level: AAA
Availability: 5% rostered
2026 AAA Stats: 24 G,.234/.327/.372, 16 R, 3 HR, 5 SB 

The Twins’ No. 4-ranked prospect, Kaelen Culpepper, is one of the most well-rounded infielders in the system, and no, he is not related to former Minnesota Vikings quarterback Daunte Culpepper. He does, however, feature an advanced hit tool and has produced at every level of the minors. Offensively, the 23-year-old out of Kansas State brings a polished approach and strong bat-to-ball skills, allowing him to make consistent contact while limiting strikeouts.

Across High-A and Double-A last season, Culpepper slashed .289/.375/.469 with 20 home runs, 16 doubles, and 25 stolen bases, while posting a 17.4% strikeout rate and a 9.7% walk rate, good for a 138 wRC+. Although he hasn’t fully broken out in Triple-A this season, he appears to be heating up after snapping out of a slump with a two-homer game.

Here’s a breakdown of his Triple-A season so far from a Statcast perspective. Notice the consistent red throughout his hard-hit metrics and speed.

Defensively, Culpepper offers quick feet, a strong arm, and solid instincts. Although scouts have debated whether he will remain at shortstop or eventually move to second or third base, he projects as an above-average everyday infielder either way. At the big-league level, the Twins’ infield features Brooks Lee, Luke Keaschall, Royce Lewis, and utility option Tristan Gray. Lee, Lewis, and Gray have been above-average hitters so far, while Keaschall has struggled with a 44 wRC+.

Lewis, despite his production, has also dealt with recurring injuries and remains just one soft-tissue issue away from another IL stint. If Keaschall continues to struggle, he could be optioned, given his remaining three minor league options. Meanwhile, although Gray has been productive in a limited role, posting a 115 wRC+ over 50 plate appearances, he is still a 30-year-old former 13th-round pick with a career 30.3% strikeout rate across 172 MLB plate appearances, making it unlikely he would keep Culpepper down.

In shallower leagues, Culpepper may not move the needle immediately, but in 15-team formats, he is worth monitoring closely. He profiles as a solid middle-infield option once called up. Keep a close eye on Keaschall’s performance and Lewis’ health, as any instability could open the door for Culpepper as early as late May or June.
