April 7: The Cardinals made these moves official today. To open the necessary 40-man spot, left-hander Zack Thompson was transferred to the 60-day IL. He was shut down in early March due to a tear in his left lat muscle. He is now ineligible to be reinstated until 60 days from Opening Day, which would be late May.
April 6: The Cardinals are planning to place catcher Ivan Herrera on the injured list due to left knee inflammation tomorrow, as club manager Oli Marmol told ESPN’s Buster Olney on this evening’s Sunday Night Baseball broadcast. Marmol added that initial test results came back clean on Herrera’s knee and that it remains structurally sound despite the impending IL placement. As relayed by Derrick Goold of the St. Louis Post-Dispatch, the Cardinals will select the contract of catcher Yohel Pozo to pair with Pedro Pages behind the plate while Herrera is on the shelf. A 40-man roster spot will need to be vacated to accommodate Pozo.
As noted by Goold earlier today, Herrera’s injury occurred during Game 1 of a double-header between the Red Sox and Cardinals this afternoon and required Herrera to be helped off the field after he felt discomfort when running from first to third on a single. Herrera appeared to be doing better later in the day, as John Denton of MLB.com notes that the backstop was moving around the clubhouse without pain during the layoff between today’s two games against Boston. Even so, it’s hardly a surprise that Herrera is headed for the injured list given physical toll that catching takes on a player’s knees. With Herrera suffering from knee inflammation, that could mean a fairly significant absence even with imaging having revealed no structural damage.
It’s a substantial loss for the Cardinals. Herrera has enjoyed a scorching start to the year, hitting .400/.455/1.100 in his first 22 plate appearances this year with four home runs, three of which came during a single game against the Angels earlier this week. That’s obviously a small sample size, but even Herrera’s career slash line in the majors entering play today sat at an impressive .296/.371/.444, good for a wRC+ of 130 across 102 games. That’s a strong mark for any hitter, but it’s nothing short of phenomenal from the catcher position and would make Herrera one of the best offensive backstops in the sport if maintained over the full 2025 campaign.
Any hope of that will have to be put on hold for now, however, as Herrera is ticketed for the injured list for the foreseeable future. In the meantime, it appears that Pages will step in as the club’s regular catcher. Pages has gotten off to a solid start this year in his own right, going 4-for-10 with a double and a homer against just one strikeout in five games. The 26-year-old is generally not regarded as offering the same offensive ceiling as Herrera, however, and hit just .238/.281/.376 in 68 games for the Cardinals last year. With that being said, he’s a solid defensive catcher who can offer consistently passable offense behind the plate and should have little trouble holding things down while Herrera is away.
Perhaps more interesting than Pages’s turn as the starting catcher is the club’s plans for the backup catcher spot on the club. Veteran Willson Contreras spent the entirety of his big league career as a catcher until this offseason, when the Cardinals moved him to first base. Though generally regarded as an average-to-below-average defensive option behind the plate, Contreras has generally been serviceable as a bat-first catcher throughout his career. That made it something of a shock that the club is not only opting to call up Pozo to serve as Pages’s backup, but that the club didn’t even use Contreras behind the plate during today’s double-header, instead having Pages catch nearly two full games. That suggests that Contreras won’t even be used behind the plate on an emergency basis, even though a lineup with him behind the plate and Alec Burleson or Luken Baker at first base would surely be more offensively robust than one featuring either Pages or Pozo.
Regardless, with Contreras locked in at first base it seems that backup catching duties will go to Pozo for the time being. The 27-year-old made his big league debut with the Rangers back in 2021 but hasn’t appeared in the majors since. He got into 21 games with Texas that year, hitting a decent .284/.312/.378 in 77 plate appearances along the way. In the years since then, Pozo has been serving as a depth option for the Rangers, Athletics, and now Cardinals at the Triple-A level and has done nothing but rake while doing so. In 329 games across five seasons at the Triple-A level, Pozo has slashed a strong .321/.343/545. While he can’t be reasonably expected to post anything close to that in the majors, his strong work at the highest level of the minors does suggest he may be able to offer some pop in his bat, making him a solid partner for Pages behind the plate while Herrera is out.
