Today is Memorial Day, and the conventional wisdom in baseball suggests that means the current standings now have more signal than noise moving forward. Perhaps that means it’s time to take the Cardinals, who have been white-hot in recent weeks, more seriously despite the narratives surrounding their quiet offseason and slow start to the year last month. A nine-game win streak earlier this month has helped propel them to a 16-4 record over their past 20 games and a 30-23 record overall. That’s put them in a statistical tie with the Padres for the final NL Wild Card spot as things stand and just two games back of the Cubs in the NL Central.

When looking at the eight teams that have won 30+ games entering Memorial Day, it’s hard to deny that the Cardinals are the most surprising. As previously mentioned, they made virtually no additions this winter as they signed Phil Maton late in the offseason but otherwise stood pat while players like Paul Goldschmidt and Kyle Gibson departed the organization. Perhaps even more surprising is the fact that players who appeared likely to be a big part of any success the Cardinals may have had this year, like youngsters Jordan Walker and Nolan Gorman , are struggling badly. Willson Contreras was a standout at the plate last year but has been merely league average this season and is currently day-to-day with a back injury, while Nolan Arenado is hitting at a below-average clip after the Cards failed to trade him this winter. Even on-paper ace Sonny Gray has a middling 4.06 ERA through 11 starts, and closer Ryan Helsley ’s 3.50 ERA is his weakest since 2021.

Instead of the usual suspects, the Cardinals’ successes have come from unlikely places. The best hitter on the team is Brendan Donovan , who has long been a steady piece for St. Louis but now appears to be in the midst of a breakout season in his age-28 campaign with a 140 wRC+ and 2.0 fWAR across 51 games. The ace of the rotation is Matthew Liberatore , who has a 2.73 ERA in ten starts so far despite having never posted an ERA below 4.40 in the big leagues before and not even being assured of a rotation role entering camp this year. Behind Liberatore, Miles Mikolas has turned back the clock in his age-36 season to post a solid 3.51 ERA in his first ten starts and fellow veteran Steven Matz has been brilliant in a swing role with a 1.99 ERA in 31 2/3 innings of work.

All of this surprising performances beg the question: how sustainable can this be? Mikolas, Andre Pallante , and Erick Fedde are all pitching well above their peripherals so far this year. Impressive as he’s been, Ivan Herrera won’t finish the year with a wRC+ above 200. Even Donovan’s .360 BABIP must be looked at with at least some skepticism, as should the league average performance the Cards have gotten out of Victor Scott II and his .368 BABIP. On the other hand, many of the club’s more established players should be expected to improve. Gray and Contreras have both performed to their usual All-Star caliber levels when looking at the underlying metrics, Arenado’s .245 BABIP would be the lowest of his career in a full season, and Lars Nootbaar ’s solid 112 wRC+ may be just the tip of the iceberg with his discipline and power potential. There’s also some players, such as Liberatore and Donovan, whose breakouts are fairly convincing even if they aren’t locks to stay quite as good as they have been so far.

Where does that leave the Cardinals? If you look at the playoff odds over at Fangraphs , the answer is likely outside of the final playoff picture. The club is projected by the site for an 84-win season with a 39.1% chance of making the playoffs. If you gave fans in St. Louis those odds at the start of the 2025 season, the vast majority would’ve surely taken that happily. As it stands, however, winning a touch under half their games for the rest of the season would surely be a disappointing outcome after this exciting start to the season. At the same time, it’s not hard to see why projection systems might doubt the Cardinals. The NL Wild Card race has been extremely competitive so far, even with strong teams like the Diamondbacks and Braves struggling to find their footing so far. That could make St. Louis’s best path to the postseason through the NL Central, where the Cubs are projected to win 90 games and have the NL’s easiest schedule the rest of the way.
