Shocking Stat Shoes True Extent Of Cardinals' Youthful Rebuild

In this story:
The St. Louis Cardinals have been one of the older teams in the league for the last few seasons and they haven't seen much success since 2022 when Paul Goldschmidt won the National League MVP, and they went to postseason.
Since then, they're under .500. After buying at the trade deadline and trying to win last year, St. Louis came up short of the postseason and promptly entered a rebuild. This rebuild became evident because of a few moves made.
First, St. Louis let Goldschmidt, and a few other veterans walk in free agency. While this could have just been the Cardinals opting to move on from veterans, they also didn't pursue any top free agents on the market. After that, they reportedly tried trading veteran third baseman Nolan Arenado to free up money and playing time for a younger player.
In this attempt to rebuild, the Cardinals have become one of the younger teams in the league after being one of the oldest for a few years. In fact, the Cardinals have the lowest percentage of starting position players who are 28 years old or younger in the entire league.
% Starters Who Were 29 Years Old or Older
— Codify (@CodifyBaseball) April 6, 2025
(non-pitchers, thru Friday):
89% LAD
65% PHI
59% LAA
57% SEA
56% SD
54% NYM
53% TEX
49% MIN SF
47% BAL
46% CIN
44% ARI PIT
43% CHC
39% ATL
38% COL WSH TOR
37% TB
35% HOU
33% CWS NYY
32% CLE KC
31% ATH
27% DET
24% MIA
22% BOS MIL
21% STL
St. Louis is used to success, but this is set to be a rebuilding season. Once Arenado is moved to a new team and a top prospect takes over for him at third base, this percentage will be even lower.
Led by players like Masyn Winn, Jordan Walker, and Iván Herrera, the Cardinals are bound for a bright future. If the fans aren't excited about the team in 2025, they should be excited about the youth movement that's taking over St. Louis for years to come.
