How Jordan Walker is shaping the next generation of Cardinals' prospects

Jordan Walker's debut for the St. Louis Cardinals in 2023 was a momentous one. He was a consensus top-five prospect in baseball, and his showing in the minors up to that point made the St. Louis Cardinals' brass optimistic that he could replicate that success in the majors. After an initial spurt of solid production, Walker then slumped in one of the worst ways for two full years. His failures from 2023-2025 and his resurgence in 2026 have become a cautionary tale for the Cardinals and their prospects.

Jordan Walker was the youngest player to debut for the Cardinals at the time since Rick Ankiel in 1999. His off-the-charts exit velocities and power numbers made him an enticing product and a must-see player. He stood six-foot-six-inches tall at the plate. He stood tall both physically and in a narrative way.

Jordan Walker had a torrid June in 2023. He slashed .338/.427/.549 for a .976 OPS with four home runs in 21 games. That would turn out to be his strongest month all year, and he finished the 2023 season with a .787 OPS, a respectable mark for a 20-year-old rookie.

Walker then posted OPS totals of .619 and .584 in 2024 and 2025, respectively. Something was terribly wrong, and several people tried to pinpoint the issue or issues at hand. Most baseball analysts agreed that Walker was swinging at too many pitches outside the zone and hitting the ball directly into the ground when he did make contact. One explanation for his struggles in 2024 and 2025 was the fact that he skipped key developmental steps prior to his promotion.

That mistake nearly four years ago is helping to direct the Cardinals' player development today.

Jordan Walker's premature promotion is directing how Chaim Bloom and the Cardinals are handling key prospects today.

Following the 2024 season, Katie Woo, formerly The Athletic's beat reporter covering the Cardinals, published a revealing story about the errors of the once-great franchise.

"The Cardinals have lost their way, according to people within the organization interviewed by The Athletic, all of whom were granted anonymity in exchange for their candor. All described an outdated player development department, one that has hurt players like Walker," wrote Woo at the time.

"Some lamented the organization’s emphasis on directing more money to the big-league payroll, even if it meant skimping on hiring the coaches, instructors and modern technology that are vital to refining players as they progress through the minors. Those decisions have left the organization to reckon with the harsh reality that they have fallen behind their rivals."

Walker was at the epicenter of a failed player development system. He was promoted far too early, and positional changes just prior to his call up further set him back. Once in the majors, there was virtually no going back. No demotion or private work with instructors was going to be able to make up for the lost development time. It wasn't until this past spring training, in his fourth professional season, that Walker began making major strides at the plate.

Chaim Bloom took note of Walker's premature promotion and has been playing it safe with prospects since taking over as president of baseball operations just over a year ago.

JJ Wetherholt didn't debut late in 2025 despite showing signs of being ready and still being able to maintain his rookie status for 2026. After all, he had more than 200 plate appearances at Triple-A prior to his debut.

Joshua Baez was raking in Memphis all year, but Bloom opted to keep him in Memphis for 103 games for Baez to make strides with his swing decisions. Leonardo Bernal, Quinn Mathews, Cooper Hjerpe, and others were delayed in their debuts to make sure their development in the minors had mostly been complete.

Now, Bloom is playing coy about debuts in 2027 for players like Liam Doyle and Jesus Baez, two players who would certainly help the major-league squad but still need more time to develop. Both players will receive ample time in the minors next year before making their debuts with St. Louis.

Jordan Walker's struggles after a premature promotion hurt the Cardinals for nearly three years. It was a mistake that was catastrophic for the organization, and Chaim Bloom's cautious approach to prospect promotions has certainly been built out of watching what happened to Jordan Walker.
