August Top 30 St. Louis Cardinals Prospect Rankings
St. Louis, MO
By Ray Mileur

The Cardinals’ prospect board has undergone its most significant reset of the season.

The arrival of the 2026 draft class adds several high-upside players to an already deep system. Trevor Condon, Tegan Kuhns and Rocco Maniscalco immediately enter the Top 15, while Andrew Williamson, Caden Ferraro and Dee Kennedy also claim places on the board.

Those additions created difficult decisions.

Some established prospects moved down without necessarily doing anything wrong. Others have climbed because their performance demanded recognition. A few remain ranked primarily because their talent still carries considerable weight, even as injuries or inconsistency have slowed their development.

This is not a ranking built on one good week, nor is it a preseason list frozen in time. The August reset considers age, current level, positional value, proximity to St. Louis, health, scouting background, production and recent momentum.

As of August 1, 2026, here is The Cardinal Chronicle’s updated Top 30 St. Louis Cardinals Prospect Rankings.

#1 – Rainiel Rodríguez, C, Double-A

Rodríguez remains the top prospect in the organization because the combination of age, position and production is too strong to ignore.

He is one of the youngest players at the Double-A level, yet he continues to hold his own against considerably older competition. The power is real, the offensive approach continues to mature and his arm gives him a legitimate opportunity to remain behind the plate.

There are prospects with louder individual tools, but few in the system can match Rodríguez’s complete combination of ceiling, age-to-level performance and positional value.

#2 – Liam Doyle, LHP, Double-A

Doyle remains No. 2 because the strikeout ability and left-handed power arsenal still give him one of the highest pitching ceilings in the organization.

His first full professional season has included command problems and some difficult outings, but the ability to miss bats has never disappeared. The fastball remains his carrying pitch, while the secondary offerings give him the weapons needed to remain on a starter’s path.

The results have not always matched the expectations, but young power pitchers rarely arrive as finished products. The arm still belongs near the top of the board.

On the night before our new rankings came out, he struck out a career high 10 batters, in a losing contest at home against the Witicha Wind Surge.

#3 – Joshua Báez, OF, Triple-A

Báez has made his Triple-A power impossible to ignore.

He has already earned consecutive Cardinal Chronicle Player of the Month honors and continues to produce the kind of home-run totals that can change a game with one swing. The strikeouts remain part of the profile, but his improved approach has allowed the power to play more consistently.

Báez is no longer simply an intriguing collection of tools. He has become one of the most important offensive prospects in the organization and is approaching the point where St. Louis will have to determine how his bat fits into its major-league plans.

#4 – Quinn Mathews, LHP, Triple-A

Mathews holds the fourth spot because proximity, track record and recent improvement all carry weight.

He was been called up and will make his MLB debut in Toronto on the day these rankings come out.

His Triple-A season has not been spotless, particularly with the walks, but he has also delivered several dominant performances, including outings that reminded everyone why he rose through the system so quickly.

Mathews still profiles as a starting pitcher, although his eventual role may depend on whether he can consistently command the strike zone. He remains one of the organization’s most realistic near-term pitching options.

#5 – Trevor Condon, OF, Rookie

The Cardinals’ first selection in the 2026 draft immediately becomes the highest-ranked member of the new class.

Condon brings a legitimate five-tool profile, with the athleticism, speed and defensive ability to remain in center field. His offensive ceiling will depend on how the bat develops against professional pitching, but the raw ingredients are already present.

High school players require patience, and Condon remains several years away from St. Louis. Still, few players in the organization can match his combination of athleticism and long-term upside.

#6 – Leonardo Bernal, C, Triple-A

Bernal remains one of the safest prospects in the system.

He is a switch-hitting catcher who has already reached Triple-A at a young age and has established himself as one of the better defensive backstops in the organization. His arm strength, receiving ability and overall work behind the plate give him a legitimate major-league foundation.

The question remains how much offensive impact he will provide. Even if the bat settles closer to league average, his defense and positional value should give him a path to the majors.

#7 – Tanner Franklin, RHP, High-A

Franklin remains one of the pitchers rising in the ranks in the organization this season, at least in our eyes.

His fastball, physical frame and strikeout ability give him a chance to develop into more than a back-of-the-rotation starter. The Cardinals have continued developing him in a starting role after he pitched primarily out of the bullpen in college, and the transition has produced encouraging results.

The command and secondary pitches will determine his eventual ceiling, but the raw arm strength already places him among the better pitching prospects in the system.

#8 – Jurrangelo Cijntje, RHP, Triple-A

Cijntje’s promotion to Triple-A, a move that actually caught us a little off guard, keeps him firmly inside the Top 10.

The switch-pitching background makes him one of baseball’s most unusual prospects, but his future will ultimately be determined by the quality of his stuff from the right side. That is where his velocity, slider and overall ceiling are most evident.

He has already moved quickly through the upper levels and continues to miss bats. The command still needs refinement, but the potential to develop into a major-league starter remains.

#9 – Brandon Clarke, LHP, Double-A

Clarke’s season began late following surgery to repair an aneurysm in his throwing arm, but his return immediately reminded everyone why the Cardinals valued him so highly.

During his rehabilitation work, his sinker averaged better than 101 mph and reached 103.1 mph. He also showed a sweeping breaking ball capable of generating uncomfortable swings.

The durability and command questions remain significant, particularly after such a serious medical issue. Still, left-handers with this kind of velocity are rare. If Clarke can stay healthy and throw enough strikes, his stock could rise rapidly.

#10 – Tegan Kuhns, RHP, Rookie

Kuhns enters the organization with one of the highest pitching ceilings in the 2026 draft class.

The former Tennessee right-hander combines power stuff with the physical traits needed to remain in a starting rotation. His fastball and breaking pitches give him the ability to miss bats, although his command and overall consistency will need to improve as he begins his professional career.

College pitchers generally move faster than high school selections, but Kuhns should not be rushed. The Cardinals drafted him for what he may become, not simply for how quickly he can reach St. Louis.

#11 – Cooper Hjerpe, LHP, Double-A

Hjerpe remains one of the most difficult pitchers in the system to evaluate, and yet there are some pundits who are a lot smarter than I am, who would suggest he may be the best prospect in the organization.

His deceptive delivery and sweeping breaking ball can make him extremely uncomfortable for left-handed and right-handed hitters. When healthy and commanding the strike zone, he still looks like a pitcher capable of contributing in a major-league rotation.

The problem has been availability. Injuries have repeatedly interrupted his development, and the lost innings have slowed his progression. The talent keeps him near the Top 10, but the next step must be staying on the mound.

#12 – Tekoah Roby, RHP, Triple-A

Roby remains one of the more talented arms in the system, but durability continues to cloud his outlook. I have never watched him pitch so ranking him is like flying a plane by instruments.

He is currently on the 60-day injured list and is expected to miss the remainder of the 2026 season. That represents another significant interruption for a pitcher whose development has already been repeatedly slowed by injuries.

The fastball and curveball still give him considerable upside, but another lost season creates legitimate questions about his ability to stay healthy, build innings and remain on a starter’s development path.

The talent warrants a place on the board. His ranking, however, at some point soon can't continue to be based on potential alone.

#13 – Yhoiker Fajardo, RHP, High-A

Fajardo remains one of the more interesting young arms in the organization.

His ability to generate strikeouts continues to separate him from many pitchers at the lower levels. He has already experienced multiple organizations despite his young age, but that journey has not prevented him from continuing to develop.

The command and efficiency still need work. If he can reduce the traffic on the bases while maintaining his swing-and-miss ability, he could eventually develop into one of the better starters in the system.

#14 – Braden Davis, LHP, Double-A

Another talented lefty in the system, Davis slips two spots from the July rankings through no fault of his own but remains firmly in the upper half of the system.

His ability to miss bats has continued to play at Double-A, and earning Pitcher of the Week honors this past month reinforced why he could not simply disappear from the board.

The command and overall consistency still need work, but a left-hander producing strikeouts against upper-level competition belongs among the organization’s better pitching prospects.

Davis may not have the national recognition of some pitchers ranked around him, but his performance has earned this placement.

#15 – Rocco Maniscalco, SS, Rookie

Maniscalco immediately becomes one of the organization’s most interesting young infielders.

The Cardinals selected the 17-year-old shortstop with the 50th overall pick, buying into his athleticism, bat speed, defensive ability and long-term offensive potential. He also brings the bloodlines of a baseball family and was one of the younger players available in the draft.

There is considerable development ahead, and projecting teenage shortstops is never an exact science. Still, Maniscalco has the tools to remain at shortstop and the offensive upside to become considerably more than a glove-first player.

#16 – Jacob Odle, RHP, High-A

Odle remains one of the organization’s best pitching stories of the season.

The 6-foot-5 right-hander has moved from sleeper status to a legitimate prospect by combining premium velocity with a curveball and improving changeup. He has already shown the ability to overpower hitters while delivering stretches of dominant production.

His command remains the biggest question, but the arm strength and physical profile give him a higher ceiling than his draft background might suggest.

Odle earned The Cardinal Chronicle’s Pitcher of the Month award in May and continues to establish himself as one of the system’s better developmental successes.

#17 – Mason Molina, LHP, Triple-A

Molina’s promotion to Triple-A changed the way he must be evaluated.

He may not possess the overwhelming velocity of Clarke or some of the other pitchers ahead of him, but he has consistently demonstrated the ability to get hitters out. His slider, deception and overall pitchability give him a chance to contribute in multiple roles.

Molina could still develop as a starter, although his eventual major-league fit may come as a multi-inning reliever or setup option. Either way, reaching Triple-A with legitimate results makes him one of the organization’s more practical pitching prospects.

#18 – Sebastian Dos Santos, MIF, Single-A

Dos Santos has earned his place on the board through performance.

Middle infielders who can hit will always deserve attention, and Dos Santos has begun separating himself from the larger group of lower-level position players. His offensive production, athleticism and ability to handle multiple infield positions give him an intriguing foundation.

The test will be maintaining that production as he moves into the upper levels. For now, the performance is strong enough to warrant a Top 20 placement.

#19 – Tai Peete, OF, High-A

Peete remains one of the highest-risk, highest-reward prospects in the organization.

His speed, athleticism, raw power and arm strength are all legitimate tools. When everything comes together, he looks like a potential impact player capable of contributing in several ways.

The swing-and-miss concerns remain substantial, particularly against breaking pitches. Peete does not need to become a high-average hitter, but he must make enough contact to allow his power and speed to matter.

The ceiling keeps him inside the Top 20. The bat will determine whether he climbs or falls from here.

#20 – Jesús Báez, INF, High-A

He has the arm strength to handle the left side of the infield, although his eventual defensive home remains uncertain. Offensively, the flashes of impact are real as he reminds us that there are two players with the last name Báez.

Rule 5 eligibility also adds urgency to his development. The Cardinals will soon have to decide whether the tools and potential warrant protection on the 40-man roster.

#21 – Jack Gurevitch, 1B, High-A

Gurevitch has hit his way onto the prospect board, he can not, will not be ignored.

His recent stretch included one of the better offensive weeks in the system, and he continues to show the power required from a first-base prospect. Because he does not provide premium defensive value, the offensive standard will always be demanding.

So far, the bat has answered the challenge.

The next step is proving the power and approach will continue to play against more advanced pitching. If they do, Gurevitch could continue moving quickly.

#22 – Ixan Henderson, LHP, Triple-A

Henderson was assigned to Triple-A Memphis to start the 2026 season but spent the first several months on the 60-day injured list with a flexor strain in his pitching arm. He has recently launched a minor league rehab assignment with the Florida Complex League (FCL) Cardinals as he works his way back into the Triple-A starting rotation

He may not have the overwhelming velocity or eye-catching profile of some pitchers ahead of him, but left-handed starters who can handle Triple-A competition remain valuable. He has continued to develop his secondary pitches and has enough command to remain in consideration for a future major-league role.

His ceiling may be more practical than spectacular, but there is value in a pitcher who could provide rotation depth or multiple innings out of the bullpen.

#23 – Yairo Padilla, SS, Single-A

Padilla remains an intriguing long-term shortstop prospect in the system.

The switch-hitter brings speed, defensive ability and a strong arm, giving him several ways to remain valuable even if the power never becomes a major part of his game. His ability to reach base and create problems on the bases gives him another path forward.

He remains several developmental steps away from St. Louis, but young shortstops with athleticism deserve patience.

#24 – Emanuel Luna, OF, Dominican Summer League

Luna remains a projection-heavy ranking. Here isgo another player I haven't watched played, so I'm going by the raw data and scouting reports on this pick.

His combination of raw power, speed and physical upside made him one of the organization’s most important international additions. He has the athletic traits to develop into an impact outfielder, but he is still at the earliest stage of his professional career.

Players performing in full-season leagues have moved ahead of him for now. That does not diminish the ceiling; it simply recognizes how much development remains.

#25 – Won-Bin Cho, OF, Double-A

Cho remains one of the more fascinating players in the system.

His size, left-handed power and athleticism have always made him stand out physically. He has continued progressing through the organization and is now competing against more advanced pitching at Double-A.

The offensive consistency and strikeout rate remain concerns, but Cho is still young enough for his level that patience is warranted. There are not many players in the system who can match his raw physical upside.

#26 – Andrew Williamson, OF, Rookie

Williamson enters the rankings as one of the more polished college bats from the Cardinals’ draft class.

The left-handed-hitting outfielder combines a compact swing with speed, plate discipline and enough power to project as more than a traditional contact hitter. His defensive home will influence his ceiling, but the offensive foundation gives him a legitimate opportunity to move steadily through the system.

Williamson may not possess the same long-term ceiling as Condon, but his experience and approach could allow him to advance more quickly.

#27 – Caden Ferraro, 1B, Rookie

Ferraro’s path will be determined by his bat.

As a first baseman, he will have to produce enough power and on-base ability to justify the limited defensive profile. His college performance showed a hitter capable of controlling the strike zone and driving the baseball, giving the Cardinals reason to believe his offense can carry him.

The competition at first base within the system is growing, with Gurevitch and others also trying to establish themselves. Ferraro will have to hit, but that is precisely why the Cardinals drafted him.

#28 – Brycen Mautz, LHP, Triple-A

Mautz remains on the board because left-handed pitching near the majors carries practical value.

His ceiling may be closer to a back-of-the-rotation starter or multi-inning reliever than a frontline arm, but he has continued competing at Triple-A and remains within reach of St. Louis.

The slider is his best weapon, and his ability to command it will determine whether he can consistently retire major-league hitters. He may not be flashy, but he remains a legitimate depth option.

#29 – Deniel Ortiz, 1B/3B, Double-A

Ortiz holds onto a place near the back of the board, but the offensive pressure continues to build. I watched him during a four-game series in Springfield and I like what I saw.

Corner infield prospects must hit, and his production has not consistently matched the expectations created by his physical tools. The bat speed and raw strength still provide reasons to remain interested, but the gap between potential and production has to close.

I'm starting to see him close that gap between potential and production and will be scouting him again on the day these rankings come out.

This is an important stretch in Ortiz’s development. He still has time, but his next move on the rankings must be driven by his bat.

#30 – Dee Kennedy, SS, Rookie

Kennedy claims the final spot following a breakout college season that significantly improved his draft stock.

The Cardinals are betting on his athleticism, power and ability to remain on the dirt. His improved vision and plate discipline helped him become a more complete offensive player, while his speed gives him another tool that can affect games.

Kennedy enters behind several younger shortstop prospects, but his college experience could allow him to move quickly. He has the upside to become much more than the final name on this board.

First Five Off the Board

Ryan Mitchell, OF/SS, Single-A
Cade Winquest, RHP, Triple-A
Hancel Rincon, RHP, Triple-A
Payton Graham, RHP, Single-A
Brian Holiday, RHP, Single-A

Mitchell was the most difficult cut, because at the beginning of the season I thought he was potentially one of the most exciting players in the Cardinals farm system.

His age, athleticism and long-term upside still make him one of the more interesting lower-level players in the organization. The addition of six members of the 2026 draft class simply created more competition for the final spots in this month's rankings

Winquest, Rincon, Graham and Holiday also remain close enough to return to the board with strong performances in August.

The Takeaway

The Cardinals’ farm system continues to become deeper and more competitive.

Rodríguez, Doyle and Báez remain the established top three, while Mathews, Condon, Bernal, Franklin, Cijntje, Clarke and Kuhns complete a strong Top 10.

The 2026 draft class added athletic position players, power arms and legitimate upside at premium positions. Condon, Kuhns and Maniscalco immediately enter the Top 15, while Williamson, Ferraro and Kennedy give the lower portion of the board a fresh look.

The pitching depth is also becoming more difficult to sort. Hjerpe and Roby remain talented but carry significant health questions. Fajardo, Davis, Odle and Molina have strengthened their cases through performance. Henderson and Mautz remain practical upper-level options.

That is what a living prospect board should do.

It should respect scouting history and long-term projection, but it should also recognize development, performance and health. Draft status can open the door, but it cannot hold a ranking forever. Production must eventually matter.

By the end August, the games have cast their vote and we will see how much impact those games have on our September rankings.

Editor’s note: These rankings are based on The Cardinal Chronicle’s August reset, using current level, age, positional value, proximity, health, scouting background, production and current momentum. This remains an independent Cardinal Chronicle prospect board.
