Before this fall, he was just a St. Louis Cardinals prospect with a cute name. Now after a few weeks pitching in the Arizona desert, Darlin Saladin may have forced his way onto the 40-man roster.
A 22-year-old right-hander from San Pedro de Macoris, Saladin came into the Arizona Fall League as a relative afterthought from the St. Louis Cardinals system who was struggling to figure out just where he belonged. His 2025 season at High-A Peoria was inconsistent, both in usage and results.
After Struggling With Peoria, Darlin Saladin Dominates in Arizona Fall League
An international free agent who was signed in July 2019, Saladin made 26 appearances for the Chiefs last summer, starting 13 of those games and closing out five. He had a 4.85 ERA across 94.2 innings with 81 strikeouts, but he also allowed 87 hits and 47 walks.
But once he took the mound for the Glendale Desert Dogs, something shifted in his arsenal and his mindset.
In 11 innings over five games in AFL action, Saladin posted a 0.82 ERA with 17 strikeouts, earning a spot in the Fall Stars Game that was held on Sunday. The seven walks still sparked concerns about his command, but the strikeout rate that nearly doubled his career average suggested that the Cardinals may have unearthed a reliever who can miss bats.
Uptick in Velocity Gives Darlin Saladin Increased Swing-and-Miss Ability
What stands out most from Saladin’s fall stint is the uptick in velocity and swing-and-miss improvement. Baseball America amplified scouting reports of a fastball sitting at 94-95 mph – a bump up from the low-90s heat he had previously flashed – with his slider creeping into the mid-80s.
Standing 5-foot-11 and just 150 pounds, Saladin still has room to grow, both in size and ability. If Saladin nails down his mechanics and tightens his control, the Cardinals could view him as a multi-innings weapon moving toward upper-minors depth.
The question now is whether this hot fall was enough to earn protection on the 40-man roster. But with his performance in Arizona, Darlin Saladin may no longer be just another “cute name” in the system, but a legitimate contender for major-league contribution in the not-too-distant future.
