FRIDAY: The surgery revealed a complete tear of the quad muscle, tweets Jenifer Langosch of MLB.com, which will likely extend his recovery time to over four months.

While the news does not shift the timeline too significantly, it already seemed there was a fairly slim chance that Adams would return for the regular season or even postseason. Now, that seems all but impossible unless Adams can beat expectations.

WEDNESDAY, 11:04pm: Derrick Goold of the St. Louis Post-Dispatch tweets that Adams will undergo surgery to repair the tear on Friday.

8:01pm: GM John Mozeliak just discussed the injury in an appearance on KMOX radio, stating: “We anticipated this being a DL, but now we have to look at how we look at this club long-term,” (Twitter link via KMOX’s Benjamin Boyd).

7:43pm: The Cardinals announced tonight that Adams will miss an estimated three to four months with the injury. Given that timeline, it’s fair to suggest that there’s a chance he could miss the remainder of the regular season. MLB.com’s Jen Langosch hears that the team is still deciding whether or not Adams will undergo surgery (Twitter link).

A recovery timeline of that significance would seem to increase the chances that the Cardinals will look outside the organization eventually in order to address the need. Reynolds has plenty of power and could serve as a stopgap, but he batted just .209/.297/.394 from 2013-14 with the Indians, Yankees and Brewers in fairly regular duty, making him a questionable long-term solution.

4:05pm: Cardinals first baseman Matt Adams will miss significant time with a torn quadriceps, Derrick Goold of the St. Louis Post-Dispatch reports on Twitter. Surgery is a possibility for the 26-year-old.

The injury is said to be worse than that of fellow St. Louis outfielder Tommy Pham, who is on the 60-day DL with his own quad injury. The Cardinals had already decided to rely on Mark Reynolds at first for the immediate future, but the severity of the injury could potentially contribute to additional roster planning over the summer.

Of course, Adams has been off to a rough start, hitting just .243/.281/.375 over his first 153 plate appearances on the year. But the team certainly had good reason to expect better the rest of the way: after all, Adams averaged a .287/.327/.474 line over the prior two seasons.

Reynolds could ultimately be paired with Dan Johnson, who is in the fold at Triple-A, or a similarly available left-handed bat such as Travis Ishikawa. The team could in theory consider sliding an outfielder like Matt Holliday, Randal Grichuk or Stephen Piscotty in at first, but none of them have played the position before (at least professionally).

But if Adams will miss much of the rest of the season, it certainly seems at least plausible that the Cards will dabble in the summer trade market. Adam Lind, Justin Morneau, and Ryan Howard are among the players that could be marketed at the deadline.
