The Cardinals spent much of 2026 drawing attention for the breadth of their farm system, and one of the most intriguing arms in the mix barely got the same spotlight. That could change fast.
Tanner Franklin, a 22-year-old right-hander who stands 6'5'' and 240 pounds, has emerged as one of the organization’s most interesting pitching prospects. He is already ranked as the Cardinals’ No. 6 overall prospect, and Baseball America went a step further with a bold evaluation of his arsenal.
"After featuring prominently in the fastball Stuff+ rankings, Cardinals right-hander Tanner Franklin is again ranking highly with his cutter," Baseball America's Geoff Pontes wrote. "It’s possible that Franklin has the best starter stuff of any pitcher in the minors.
The cutter is his top secondary, and it sits around 91 mph, can get up to 97 and has true cut-ride shape. The pitch generated a 13.7 percent swinging-strike rate and a .299 xwOBA in 2026."
Franklin didn’t arrive in a headline-grabbing deal like Jurrangelo Cijntje, which meant less noise around his name as the Cardinals rebuilt by moving Nolan Arenado, Brendan Donovan, Sonny Gray and Willson Contreras before the 2026 season. That trade activity helped restock the system with elite talent, and the buzz naturally followed names such as Cijntje, Brandon Clarke, Rainiel Rodriguez, Liam Doyle, Joshua Baez and Leo Bernal.
Still, Franklin turned in a strong 2026 season of his own. The Cardinals’ 2025 second-round pick logged 25 starts between High-A and Double-A, finishing with a 3.94 ERA, 133 strikeouts and 45 walks across 105 innings.
He was even better after reaching Double-A. In six starts for Springfield, Franklin posted a 3.34 ERA with a 42-to-13 strikeout-to-walk ratio over 32 1/3 innings. His High-A work came in 19 starts and produced a 4.21 ERA.
For a pitcher who hasn’t gotten nearly as much attention as some of the other names in the system, Franklin’s profile is hard to ignore. His size, age and pure stuff give him real helium, and with the Cardinals’ 2027 rotation still unsettled beyond Michael McGreevy, Andre Pallante and Kyle Leahy, he’s a name fans should keep on the radar when Spring Training rolls around.

Cardinals Fans Just Got A Painful Reminder About That Brewers Trade
The Brewers 2-0 lead over the Dodgers in the NLCS came with a familiar sting for Cardinals fans, thanks to two former St. Louis arms helping fuel a historic night out of the bullpen. Dustin May and JoJo Romero were part of a record-setting stretch in which Milwaukees relievers threw five perfect innings, a reminder of how quickly a deadline deal can start to look different once October arrives.
St. Louis sent May and Romero to Milwaukee at the deadline in exchange for prospects Josiah Ragsdale and Alexander Frias, a move that was framed as a win-win at the time. The Brewers have already gotten meaningful postseason value from the trade, while the Cardinals are banking on the long-term upside of the young talent they brought back, which is usually the part of these deals that takes a little longer to judge.

Jordan Walker Just Raised A Big Cardinals Question
Jordan Walkers 2026 season gave the Cardinals plenty to like, and then some. He stayed on the field for a career-high 158 games, earned his first All-Star nod and finished as a Hank Aaron Award finalist, all while putting together a .269 average with 22 home runs and 102 RBIs. For a young hitter whose development has been watched closely in St. Louis, that kind of production was a meaningful step forward and a sign he can already anchor a big part of the lineup.
The bigger question now is what comes next for both Walker and the Cardinals. His rise has made him more than just a breakout story, because seasons like this tend to change how a club thinks about long-term planning and a players place in it. Even with the strong overall numbers, the team still has reason to monitor whether the next step is refinement, durability or something even more important in the months ahead. [Read more 🡒]
D-Backs Could Regret Letting This Bullpen Breakout Get Away
The Cardinals bullpen issues were hard to miss in 2026, when the group finished with a 4.40 ERA and tied for third in the league with 30 blown saves. That kind of late-inning instability tends to send a front office shopping for arms that can shorten games, and Jonathan Loaisiga fits the profile as well as anyone on the market.
Loaisiga worked in 67 appearances for the Diamondbacks and posted a 2.42 ERA, a strong enough season to make him one of the more intriguing relievers now heading into free agency. For a St. Louis club looking to steady the back end, his track record gives them a clear reason to be in the mix, even if plenty of teams will see the same opening and come calling. [Read more 🡒]
