Ranking the 15 best St. Louis Cardinals players under 25

#11 RHP Michael McGreevy

Prior to this season, Michael McGreevy would have been at risk of being off this list entirely. However, thanks to impressive outings in the majors this year, his name has re-entered these rankings as a valuable future player. McGreevy, 24, made four appearances -- three starts -- this year for the Cardinals with a 1.96 ERA and 18 strikeouts in 23 innings. Following his promotion to the majors for a spot start on July 31st, McGreevy was able to turn it on in Triple-A Memphis. He stands to be a solid bottom-of-the-rotation starter for several years.

#10 INF Thomas Saggese

I won't go too in-depth on Thomas Saggese's minor league success; rather, I'll focus on his potential. He has the ability to be a plus defender at second base and third base while also providing some pop from the right side of the plate. Saggese, 22, finished his major-league stint with a .204/.250/.306 slash line in only 49 at-bats. Though Saggese's major league display this year left some to be desired, he still has the potential to be a quality role player.

#9 C Ivan Herrera

Ivan Herrera has been toyed with all year, yet he's still been able to provide plus offense for the Cardinals. Despite not receiving regular playing time and being relegated to a bench role for most of the season, Herrera was still able to finish 2024 with a .301/.372/.428 slash line and five home runs in only 229 at-bats. He has work to do on the defensive side of the game, particularly with game calling, but Herrera stands to be a potent offensive player for years to come.
