St. Louis Cardinals Farm System: The Cardinals’ farm system is surging with breakout bats, high-octane arms, and a wave of upside talent—from JJ Wetherholt to Liam Doyle—that’s reshaping its long-term outlook.
Summary
The Cardinals’ system is in the best shape it’s been in for years! This year’s crop features breakout performers, toolsy projection bets, and pitchers with swing-and-miss stuff who are either refining their arsenals or battling durability concerns. JJ Wetherholt headlines the class as a polished, big-league-ready bat with elite contact skills and top-of-the-order potential. Liam Doyle, selected fifth overall, adds a power lefty with a deceptive splitter and starter traits. From Joshua Baez’s electric 20–50 season to Rainiel Rodriguez’s offensive emergence behind the plate, the system is showing signs of depth and dynamism.
On the mound, the organization is rich with variance. Tink Hence still flashes top-30 starter ceilings, but health remains the swing factor. Meanwhile, arms like Ixan Henderson and Nate Dohm are refining their pitch mixes and command, pushing toward mid-rotation roles. Chen-Wei Lin and Sem Robberse offer big stuff but come with volatility.
Positionally, the system features a handful of contact-oriented bats with defensive value, including Nathan Church and Jimmy Crooks, while Jesus Baez and Leonardo Bernal offer more offensive upside with questions around zone control and long-term roles. Yairo Padilla and Ryan Mitchell headline the younger tier, flashing foundational tools that could grow into impact profiles.
AI-Assisted Fantasy Tiers: Methodology and Observations
AI has made significant strides in all aspects of our lives. Over the past four years, I have compiled 500,000 words of personal scouting narratives, which have formed the foundation for training my own AI assistant. This assistant now evaluates prospects and assigns fantasy tiers exclusively based on the insights and observations contained in my write-ups.
After requesting that my AI assistant generate fantasy tiers using this year’s reports, I found that the AI’s rankings generally align with my own assessments. However, there are some cases where the AI’s evaluations differ from my personal rankings. I am sharing those differences here for your consideration.
🥇 Tier 1: Fantasy Impact Targets
- JJ Wetherholt – Elite hit tool, OBP monster, plus speed. Could be a .300 hitter with 20+ steals and top-of-the-order production. Immediate fantasy relevance.
- Liam Doyle – Swing-and-miss lefty with a deceptive splitter. Could be a high-strikeout SP2 if he stays healthy.
- Joshua Baez – 20–50 season speaks for itself. If the contact gains hold, he’s a fantasy unicorn with power/speed upside few can match.
🥈 Tier 2: Everyday-Upside Targets
- Tink Hence – He’s athletic with a top-of-the-rotation arsenal. His problem has been staying on the field.
- Rainiel Rodriguez – Offensive catcher with zone control and bat speed. If he sticks behind the plate, he’s a rare fantasy asset.
- Jesus Baez – Bat speed and power projection are real. If he controls the zone, he could be a 20+ HR infielder with run production.
- Ryan Mitchell – Toolsy prep bat with power/speed foundation. Long runway, but center field profile could pop.
- Yairo Padilla – Plus defender with bat-to-ball skills and speed. Needs strength, but could be an impact contributor.

2026 Player Profiles
1. JJ Wetherholt (SS/2B)
- Highest Level: Triple-A ETA: 2026 Fantasy Ceiling: Top 15 SS/2B
- Last Updated: 10/17/2025
- Tools Summary: Elite hit tool, OBP monster, plus speed. Could be a .300 hitter with 20+ steals and top-of-the-order production. Immediate fantasy relevance.
JJ Wetherholt entered the 2024 draft cycle as the early favorite for the 1:1 pick, but a hamstring injury cost him a significant chunk of the season and ultimately dropped him to seventh overall, where the Cardinals made the selection. Despite the missed time, his offensive foundation remains elite.
He’s a high-floor hitter with exceptional contact skills and plus speed. While not a burner, his instincts and efficiency on the bases should yield 20+ stolen bases annually. He’s not particularly physical, but he produces above-average exit velocities, and with added leverage, could grow into average power. What he will do—consistently—is hit. He’s walking more than he strikes out, with excellent chase discipline and elite in-zone contact rates.
Fantasy managers should treat Wetherholt as a top-of-the-order catalyst with immediate value in batting average, OBP, and stolen bases. The power sits in the 10–12 HR range, but the hit tool is the engine—and it’s big-league ready.
2. Liam Doyle (LHP, #5)
- Highest Level: DNP ETA: 2027 Fantasy Ceiling: Top 30 SP
- Last Updated: 10/17/2025
- Tools Summary: Swing-and-miss lefty with a deceptive splitter. Could be a high-strikeout SP2 if he stays healthy.
Liam Doyle was selected fifth overall in the 2025 Draft, signing for $880,000 below slot value. After transferring to Tennessee for his draft year, he delivered the best season of his college career: a 3.20 ERA with 154 strikeouts across 95.2 innings, while trimming his walk rate to just three per nine. It was a breakout campaign that solidified his status as one of the top arms in the class.
He features a three-pitch mix headlined by a fastball that reaches the upper 90s, a solid slider, and a standout splitter that he deploys effectively against both arm-side and glove-side hitters. The splitter is a true weapon—especially against right-handers—giving him a rare left-handed look that can tunnel velocity and disrupt timing.
Fantasy managers should treat Doyle as a high-probability mid-rotation arm with swing-and-miss upside. The fastball/splitter combo is legit, and if the command continues to improve, he could move quickly through the system. A polished college lefty with impact potential.
3. Joshua Baez (OF)
- Highest Level: Double-A ETA: 2026 Fantasy Ceiling: Top 45 OF with upside
- Last Updated: 10/17/2025
- Tools Summary: 20–50 season speaks for itself. If the contact gains hold, he’s a fantasy unicorn with power/speed upside few can match.
Joshua Baez was envisioned as a power-speed outfielder with impact upside, but contact issues plagued his early development. He posted strikeout rates north of 30% at every level, including a 37% K-rate across 260 plate appearances in High-A during 2024—driven by excessive swing leverage and a 52% fly ball rate.
In 2025, Baez made a dramatic adjustment—reducing that leverage without sacrificing power. The results have been stunning: he cut his strikeout rate to 20%, posted a .500 SLG, and launched a career-best 20 home runs. He also swiped 54 bases in 63 attempts, joining Konnor Griffin as the only minor leaguers to post a 20–50 season.
Fantasy managers should treat Baez as a breakout power-speed asset with renewed viability in standard formats. The transformation is real, and the tools have always been loud. One of the best stories in the Cardinals system—and one of the biggest risers in Dynasty rankings.
4. Tink Hence (RHP)
- Highest Level: Double-A ETA: 2026 Fantasy Ceiling: Top 30 SP or Closer if health problems persist
- Last Updated: 10/17/2025
- Tools Summary: He’s athletic with a top-of-the-rotation arsenal. His problem has been staying on the field.
Hence spent most of the 2025 season on the IL with a rib injury, limiting him to just six weeks of action. He hasn’t been fully healthy since 2023, when the Cardinals capped his workload at 96 innings. Despite the interruptions, his arsenal continues to flash top-of-the-rotation potential.
His fastball sits at 95.5 MPH and touches 98, with high spin that generates consistent swing-and-miss. His best pitch is a changeup with excellent fade and tight tunneling off the fastball, giving him a legitimate weapon against both lefties and righties. The slider remains his weakest offering, but with his athleticism and feel for sequencing, there’s room for it to develop into a viable third pitch.
Fantasy managers should treat Hence as a high-ceiling arm with durability concerns. The stuff is electric, and the command flashes, but the path forward hinges on health and innings. If he can’t stay on the mound, there’s real bullpen risk. The upside still points to Top 30 starter territory, but until he proves he can stay healthy, he’s trending down—and gathering momentum in the wrong direction.
5. Quinn Mathews (LHP)
- Highest Level: Triple-A ETA: 2026 Fantasy Ceiling: Top 60 SP
- Last Updated: 10/17/2025
- Tools Summary: His fastball and control have declined since his 2024 breakout, but his secondary pitches are still effective.
After logging 143.1 innings across four levels in 2024, Quinn Mathews entered 2025 with momentum—but a shoulder injury derailed his season. He saw a drop in velocity, struggled with control, and spent extended time on the IL. Upon returning, he posted a promising ERA, but the command wasn’t there—walking nearly seven batters per nine innings.
Mathews leans heavily on his secondaries to generate outs, led by a 70-grade changeup and a plus slider. The changeup is his signature pitch, thrown effectively to both arm-side and glove-side hitters. It’s a legitimate weapon. But until he gets back to consistently throwing strikes, the ceiling needs to be recalibrated.
Fantasy managers should treat Mathews as a speculative hold with a premium pitch mix and health-dependent upside. If the shoulder issues are fixable, the arsenal still plays. But that’s a big “if”—and one that clouds the path forward.
6. Rainiel Rodriguez (C)
- Highest Level: High-A ETA: 2027-28 Fantasy Ceiling: Top 20 Catcher with upside
- Last Updated: 10/17/2025
- Tools Summary: Offensive catcher with zone control and bat speed. If he sticks behind the plate, he’s a rare fantasy asset.
Raniel Rodriguez attended high school in North Philadelphia but returned to the Dominican Republic to qualify for the 2024 signing period—a strategic move that paid off with a $300,000 bonus. He emerged as one of the top performers in the DSL in 2024 and followed it up with a strong 2025 campaign.
Rodriguez dominated the Florida Complex League, slashing .373/.513/.831 before earning a May promotion to Low-A. The jump in level proved more challenging, but he maintained an 18% contact rate and a 46% flyball profile. His .385 BABIP regressed to .261, dragging his average down to .249. Assuming a more sustainable .310 BABIP, a .260 average feels like a reasonable baseline. He capped the year with a brief stint in High-A, where he’s likely to open 2026.
At 5-foot-10, Rodriguez is slightly undersized for a catcher, but he’s added strength and improved his defense since signing. His arm is strong, and his offensive game remains the calling card—featuring excellent bat speed and a short, direct swing path.
Fantasy managers should treat Rodriguez as a developmental catcher with offensive upside. Dynasty investors will need patience, but if everything clicks, there’s a 15+ HR bat with positional scarcity baked in.
7. Yairo Padilla (SS)
- Highest Level: Complex ETA: 2028 Fantasy Ceiling: Top 15 SS with risk
- Last Updated: 10/17/2025
- Tools Summary: Plus defender with bat-to-ball skills and speed. Needs strength, but could be an impact contributor.
Yairo Padilla signed with the Cardinals in 2024 for an impressive $764,000 bonus, and he’s already showing why. He’s an extremely athletic shortstop with plus speed and excellent bat-to-ball skills. While he’s currently hitting everything into the ground, that’s more a reflection of his present strength than his swing mechanics. He doesn’t turn 18 until June, and at 6 feet tall, he has the frame to add meaningful muscle.
Defensively, Padilla is a plus glove at shortstop with the range, actions, and instincts to stay there long-term. Offensively, he had a strong season despite the lack of physicality—slashing .283/.396 while controlling the zone with a 14% strikeout rate and 12% walk rate.
Fantasy managers should treat Padilla as a high-upside developmental stash. The foundation is already in place, and once the strength comes, the profile could take off. Consider him a long-term play with considerable upside.
8. Blaze Jordan (1B/3B)
- Highest Level: Triple-A ETA: 2026-27 Fantasy Ceiling: Corner Infielder with upside
- Last Updated: 10/17/2025
- Tools Summary: There has been more power in 2025, and he’s performing better against right-handed pitching. Perhaps they are related.
Blaze Jordan has been an enigma since being drafted out of high school in 2020. As an amateur, he was lauded for his immense raw power, but translating that into consistent in-game production took time. In 2025, the power began to show up more reliably—he posted a .450 SLG with 19 home runs across Double and Triple-A, all while maintaining an impressive 11% strikeout rate.
Jordan’s biggest challenge has long been hitting arm-side pitching, particularly right-handers. In 2024, he crushed lefties with a 1.130 OPS but managed just a .595 OPS against righties. That gap narrowed significantly in 2025, and he now shows only modest platoon splits—a meaningful step forward.
Fantasy managers should treat Jordan as a corner infielder with upward-trending power and improved viability against right-handed pitching. This has been his most encouraging season yet, and following his trade to the Cardinals, the path to big-league playing time looks clearer. If the power continues to trend up, there’s real fantasy upside.
9. Jesus Baez (3B/SS/2B)
- Highest Level: High-A ETA: 2027 Fantasy Ceiling: Top 15 3B
- Last Updated: 10/17/2025
- Tools Summary: Bat speed and power projection are real. If he controls the zone, he could be a 20+ HR infielder with run production.
Jesus Baez possesses some of the best bat speed in the minor leagues and projects as a future 20+ home run threat at the highest level. He’s a free-swinger by nature, but he makes excellent contact and has started to draw more walks. As he climbs the ladder and faces better pitching, his aggressive approach could be tested—pitchers may exploit it to induce weak contact. That said, the early signs of zone control are encouraging.
Physically, Baez is stocky with a strong lower half. He’s an average runner now, but stolen bases aren’t likely to be a major part of his game long-term. Defensively, he’s splitting time between shortstop and third base, but the hot corner looks like the better fit over time given his build and range.
Fantasy managers should treat Baez as a bat-first infielder with breakout potential. There’s a full-time regular lurking here, and potentially more if he continues refining his approach and controlling the strike zone. The bat speed is real, and the power is coming.
10. Ixan Henderson (LHP)
- Highest Level: Double-A ETA: 2026 Fantasy Ceiling: Top 50 SP with upside
- Last Updated: 10/17/2025
- Tools Summary: He doesn’t possess a blazing fastball, but with a strong change-up and a significantly improved slider, he could develop into a mid-rotation starter.
Ixan Henderson was selected by the Cardinals in the eighth round of the 2023 Draft and delivered a strong 2024 campaign, posting a 2.34 ERA across Low and High-A. He did it with a fairly average arsenal, which raised questions about how well his stuff would hold up against upper-level hitters. But in 2025, things clicked. With an improved pitch mix, he made 25 starts and posted a 2.59 ERA with 134 strikeouts and 51 walks.
Henderson works with a sinker/slider/changeup trio. His sinker sits in the low 90s and sets up his best pitch—a changeup that’s particularly effective against right-handed hitters, who batted below the Mendoza line against it. His most improved offering is the slider, which has evolved into a sweeper. While we don’t have horizontal metrics on it, the results are telling: left-handed batters are chasing it with awkward swings.
Fantasy managers should treat Henderson as a potential backend starter with room to grow. If the sweeper proves to be a true weapon, his ceiling could push higher. The pitch mix is trending up, and the command is holding—there’s a path to relevance here.
