2026 Top 50 Cardinals Prospects: 1-5

2026 Top 50 Cardinals Prospects: 1-5

Here is the final 5 of the prospect rankings; and there should be no surprised here. 4 of the 5 we could see as early as this year.

1. J.J. Wetherholt

Position: SS / 2B / 3B
Height/Weight: 5’10″/190
Bats/Throws: L/R
Born: 09/10/2002 (Age 23)
Drafted: 1st Round (7 overall) in 2024 Draft
Highest Level: AAA (2025)
MLB ETA: 2026

Hit Tool – Plus Plus (70 grade): Considered one of the best pure hitters in minors; consistently posts elite in-zone contact rates and a 48% HardHit%; shows the ability to adjust with two strikes; profiles as a top-of-the-order bat with exceptional discipline and bat-to-ball skill.

Power – Average to Above Average/Plus (50–55): Lacks top-end raw power (max EV ~107.6 mph); generates strong game power by selling out early in counts and lifts the ball consistently; recorded 17 HR in 2025 across AA/AAA with excellent contact quality; projected for 12–20 HR annually with lots of doubles.

Speed – Average to Above Average/Plus (55): Speed is instinctual and efficient; projecting 20+ steals annually despite average raw foot speed; smart, opportunistic baserunner who adds value without needing elite speed.

Defense – Above Average/Plus (60): Capable of handling SS, 2B, or 3B; BA lists him as best defensive infielder and best infield arm in the system; expected to move between second and third depending on roster fit.

Approach/Baseball IQ – Plus Plus (65-70): Rarely chases, walks nearly as much as he strikes out, and adjusts his plan mid-at‑bat; situational hitting and plate coverage are part of what makes him a high‑floor, high‑probability MLB regular; could be clubhouse leader time in quick time.

There is not much to say that hasn’t already been said. Wetherholt is an elite prospect; unfortunately so was Jordan Walker and Dylan Carlson at one point. What helps Wetherholt is his timing in the system; Chaim Bloom’s updated farm system should mean he’s got the tools to succeed. Personally, I’m starting him at 3B when the season kicks off because Nolan Gorman didn’t seem comfortable there last season, and Wetherholt has the defense to succeed there.

Overall Projection
Ceiling: All-Star, franchise cornerstone; the kid can hit and is very mature for his age.
Floor: Everyday infielder with unremarkable career; he’s good enough to play everyday, even if all the tools don’t continue to develop.
Most Likely Outcome (2026–27): He’ll be in rookie of the year contention and have a solid season with ups and downs.

2. Liam Doyle

Position: Pitcher
Height/Weight: 6’2″/220
Bats/Throws: R/L
Born: 06/03/2004 (Age 21)
Drafted: 1st Round (5 overall) in 2025 Draft
Highest Level: AA (2025)
MLB ETA: 2026–27

Pitches:
Fastball — Above Average/Plus to Plus‑Plus (60–70): Sits mid‑90s, touching 98–100 mph at peak; high release, flat plane, explosive carry up in the zone; elite whiff pitch.
Slider — Above Average/Plus (60): 82–85 mph with strong horizontal sweep; flashed plus traits, but leaves it in the middle of the plate too often; when sharp, can be a legitimate strikeout pitch vs lefties and righties.
Cutter — Average (50): Upper‑80s used as a third look; occasionally leaves it up or over the heart, same issue as slider; if refined, could neutralize righties and round out a true 3‑pitch main mix.
Splitter/Change Variation — Below Average (40–45): Not a go‑to pitch yet as it’s inconsistently used; Could be a key piece as a starter long‑term.

Command/Control — Below Average (40-45): Max‑effort delivery leads to spotty command at times; real reliever risk due to limited repertoire and max‑effort delivery; fastball command is significantly ahead of his secondaries.

Doyle is a very interesting pitcher. He could probably start the season in the bullpen and be successful; his long-term future in the rotation, so they can take half a season and see what happens. He could be up in 2026 if everything breaks right, including better command of his secondary pitches.

Overall Projection
Ceiling: No. 1–2 MLB starter if the secondaries sharpen and command stabilizes; Fastball is elite enough to anchor a rotation spot.
Floor: High‑leverage lefty reliever, potentially dominant, thanks to elite FB/SL combo.
Most Likely Outcome (2026–27): Mid‑rotation starter with strikeout upside in 2027; multi‑inning monster if shifted to relief for a 2026 debut.

3. Rainiel Rodriguez C Hi A

Position: Catcher
Height/Weight: 5’10″/197
Bats/Throws: R/R
Born: 01/04/2007 (Age 19)
Signed: 04/01/2024 for $300k bonus
Highest Level: Hi A
MLB ETA: 2028

Hit Tool – Above Average/Plus (60): Shows advanced plate discipline for his age; selectivity early in counts; avoids selling out for power; walk and strikeout trends reinforce a mature approach; ability to maintain a competitive K-rate even as climbing levels shows reliable bat-to-ball skill and pitch recognition.

Power – Above Average/Plus (65): already demonstrates real game power; .279 ISO and 52.5% pull rate, showing efficient translation of strength to damage; 111.1 mph max EV, an elite figure for an 18-year-old; fly-ball oriented batted-ball profile suggests sustainable power production.

Speed – Below Average (40): Not a basepath threat; doesn’t impact catching ability.

Defense – Above Average/Plus (60): considered a potential future elite catching prospect due to strong foundational defensive traits; still refining details of catching.

Approach/Baseball IQ – Above Average/Plus (60): Advanced approach for age; 145 wRC+ at Class-A Palm Beach as an 18-year-old (1 of 15 players 18 or under to do so); statistical comps of Mike Trout, Bryce Harper, Fernando Tatis Jr. as elite teenage players.

Rodriguez looks like he could be something special – a power hitting, above average defensive catcher who looks better than his age would suggest. That age could also be a downside, as there have been a few teenage phenoms that never put it all together. Right now, he’s a back end Top 100 prospect in baseball and a testament to what Bloom regime is preaching.

Overall Projection
Ceiling: Multi-time all star catcher with 30 homers; all signs point to a rare combination of skills at this age.
Floor: Everyday catcher with power; he won’t blow anyone away with any facet of his game, but be good enough to appreciate.
Most Likely Outcome (2026–27): Probably not in the picture until 2028; the team can be patient with him with all the upper level catching depth they have.

4. Jurrangelo Cijntje

Position: Pitcher
Height/Weight: 5’11″/200
Bats/Throws: S/S
Born: 05/31/2003 (age 22)
Drafted: 1st Round (15 overall) in 2024 Draft by Mariners; acquired with 2 others from the Mariners for Brendan Donovan
Highest Level: AA
MLB ETA: 2026

Right Side Pitches
Fastball – Above Average/Plus (60): Sits 95–97 mph, touches 98–99 mph; above‑average life up in the zone; hitters routinely struggle to catch up; projects as an MLB‑caliber bat‑miss weapon.
Slider – Average to Above Average/Plus (55): Mid‑80s, cutter‑like action at times; depth and power are strong; needs a bit more command for full plus status.
Changeup – Average (50): Firm at 87–89 mph with late fade; produces ground balls more than swings & misses.

Left Side Pitches
Fastball – Average (50): 90–92 mph, thrown from a lower slot that tunnels well with his slider.
Slider – Average to Above Average/Plus (55): Low‑80s sweeping action; used primarily vs. left‑handed hitters.

Command/Control – Below Average to Average (45): Grade for both sides; command is a little better on right side; walked 4.24 per 9 in 2025; still developing pro‑level command; college career shows steady improvement, cutting his walk rate significantly between 2023 and 2024 while developing more consistent mechanics from the right side.

Cijntje will focus on throwing right handed in games, while throwing from the left side in bullpen sessions to keep the arm active; he’s currently considered the best ambidextrous pitcher evaluated. It’s probably for the best to stick with one hand, as he’s got some work to do. His command has improved over time, so it’s fair to assume he’ll keep getting better; look as the progress of walk and homer numbers since college. (Full scouting report with comps here)

Overall Projection
Ceiling: #2 starter; if that command continues to improve, he can get there.
Floor: Mop-up guy; even with his small frame, he’s been able to increase his work load each year since his freshman year of college.
Most Likely Outcome (2026–27): Late 2026 at the earliest as a spot starter/reliever, and that’s if he takes the step forward with control. More likely 2027.

5. Joshua Baez

Position: OF
Height/Weight: 6’3″/220
Bats/Throws: R/R
Born: 06/28/2003
Drafted: 2nd Round (54 overall) in 2021 Draft
Highest Level: AA
MLB ETA: 2026

Hit Tool – Average to Above Average/Plus (55): biggest developmental story is his contact improvement; adopted a more all-fields approach; began making contact at the best rate of his career in 2025; still needs to work on pitch recognition and strikeouts.

Power – Above Average/Plus (60): known for premium raw power; pop in his bat; size looks bigger in box; elite bat speed, physicality, and plus raw tools dating back to his signing; capable of towering home runs, including multiple documented 400+ foot shots.

Speed – Above Average/Plus (60): 54 stolen bases in 2025, tied for MiLB lead; speed considered legitimate secondary weapon.

Defense – Average (50): Toolsy outfielder with strong athleticism; size and speed suggest corner outfield spot with solid range; defensive value will hinge on reads and consistency.

Approach/Baseball IQ – Average (50): Hard worker; overcame early challenges to breakout in 2025.

Baez is the poster boy for Bloom right now; he was pretty much written off as a legit prospect prior to 2025 when he broke out. Baez went from a pull hitter to hitting to all fields, which stabilized his swing path and cut down on whiffs. He also was fully healthy for the first time in a while, which kept everything consistent.

Overall Projection
Ceiling: 30/30 corner outfielder; he’s got the power/speed combo and should be able to maximize it in the Majors.
Floor: Power off the bench; he won’t be a true 4th outfielder, but he could be in the field in a pinch and supplies power late in games.
Most Likely Outcome (2026–27): He could be the Walker replacement this season, if he takes another step forward and Walker does nothing.

I’ll be back next week with a prospect follow up, including the Prospect Tracker with rankings from other websites/publications.
