The Cardinals may have landed a pitcher who could help them in the bullpen almost immediately, but that does not mean they are likely to treat Cal Randall like a quick fix.
St. Louis used the fifth-round pick on the UCLA right-hander, and the appeal is obvious: Randall owns the best fastball in the 2026 MLB Draft class, with Baseball America giving the pitch an 80 on the 20-80 scouting scale. The heater lives in the upper 90s, reaches 101 MPH, and stands out because of the way he delivers it - top-end extension, a low release point, and elite spin and ride all help make the pitch play even bigger.
The rest of the package is still a work in progress. Randall’s slider and changeup are both below average right now, and his control is in that same bucket.
But the fastball is so loud that draft expert Joe Doyle sees a path for Randall to help St. Louis right away if the Cardinals choose to keep him in relief.
"The Cardinals are taking UCLA righty Cal Randall in the 5th. It's one of the best fastballs in the class.
Diabolical from a Stuff+ perspective. And results match the math.
He's either an immediate 8th inning high-leverage arm, or an interesting project."
Randall’s 2026 numbers back up the hype. He struck out 44.2%(!!!)
of the batters he faced, and even though he leaned on the fastball 90% of the time, hitters still missed it 36% of the time. That kind of swing-and-miss is rare anywhere, let alone on a pitch that comes in that often.
For context, Mason Miller is getting whiffs on 47.5% of swings against his fastball this year, and only Fernando Cruz and Andres Munoz are above 40% among the rest of the pitchers mentioned in the source. Across all of baseball, only five pitchers are generating whiffs on their fastball at a rate above 36%.
So yes, the Cardinals could move Randall quickly if they wanted to. But based on how this front office has operated lately, the more likely play is to chase something bigger than an instant bullpen arm.
St. Louis appears willing to see whether Randall can become a starter, or at least sharpen his secondaries enough to grow into a true late-inning weapon.
That approach fits what the Cardinals did last year with Tanner Franklin, the 72nd overall pick out of Tennessee. Franklin came in with a 70-grade fastball that touched triple digits and carried strong underlying traits of its own.
He was viewed by some as a surprise second-round selection, but over the last 12 months he has climbed national prospect lists, with several outlets putting him in the Cardinals’ top five and some hinting at a top-100 place in all of baseball. Keith Law of The Athletic has already ranked Franklin as the 25th-best prospect in the sport.
Randall is even more raw beyond the fastball than Franklin was, which makes the developmental challenge bigger. If the Cardinals want him to succeed as a starter, they will need to keep pushing the secondary pitches and the command instead of letting him live off the heater against lower-level hitters. The idea is to build a pitcher who can thrive in the majors, not just dominate where he is assigned.
That patience is the point. Randall’s likeliest outcome may still be the bullpen, and he could end up as one of the best relievers in the game. But the upside as a starter is significant enough that the Cardinals seem intent on finding out how far they can take him before settling for the shorter route.
St. Louis has accelerated arms before, including Ryan Helsley and Jordan Hicks, to help the bullpen.
Both had starter-level potential if they had been given more runway. This time, the Cardinals appear more willing to let the long-term upside guide the plan, with relief still there as the fallback if the starter path does not come together.

Cardinals Phenom Just Took A Huge Step As Rotation Questions Linger
Jurrangelo Cijntjes rise through the Cardinals system has taken another meaningful step, with the switch-pitcher moving up to Triple-A as St. Louis keeps sorting through its long-term rotation picture. The organization has seen enough progress to push him to the next level, and that matters for a club that has been trying to build more pitching depth from within while also weighing how its young arms fit into the bigger picture.
Cijntjes numbers have trended in the right direction over the course of the season, with his ERA coming down and his strikeout total climbing in recent weeks. The Cardinals also have a clear investment in him after acquiring him in the Brendan Donovan deal with Seattle, and his next stretch in Memphis will go a long way toward showing how close he is to becoming part of the conversation in St. Louis.

Cardinals Let A Productive Bat Walk Without A Real Shot
Bligh Madris put together a strong season at Triple-A Memphis, but it never translated into a real look with the Cardinals. The left-handed bat produced enough to keep himself in the conversation, yet St. Louis had first base and designated hitter playing time spoken for, and the club continued leaning toward younger options as it sorted out its roster priorities.
Now Madris is moving on after being released, closing the door on a stint that never quite opened at the big-league level. He has had limited success in three major league seasons, and after previous stops overseas and a productive run in Memphis, the next chapter is taking shape away from the Cardinals. [Read more 🡒]
Cardinals Fans Have Every Right To Wonder About JJ Wetherholt Now
The Cardinals still have plenty of representation headed into the 2026 MLB All-Star Game, with three players and manager Oli Marmol already selected, but the omission of rookie JJ Wetherholt is the one that stands out. Wetherholt has played well enough to sit near the front of the National League Rookie of the Year conversation, so his name being left off the initial roster naturally caught attention, especially after fan voting did not get him into the starting lineup.
Now the focus shifts to whether the story is actually finished. There is still some buzz around Wetherholts All-Star case, and Cardinals fans have every reason to keep an eye on how the roster settles from here, because a late opening could change the picture for a player who has already done plenty to earn a bigger stage.
