Cardinals already facing injury attrition in rotation and outfield

Cardinals manager Oliver Marmol informed the club’s beat Friday, including Lynn Worthy of the St. Louis Post-Dispatch, that right-hander Sonny Gray will start the season on the 15-day injured list. Outfielder Lars Nootbaar will start the year on the 10-day IL. Left-hander Zack Thompson will get a rotation job to start the season while fellow lefty Matthew Liberatore will be in the bullpen.

Gray was diagnosed with a right hamstring strain a couple of weeks ago and has been working his way back to health since then. Gray says he’s been healthy for about 10-to-12 days, per John Denton of MLB.com, but hasn’t had enough game action to be ready for the start of the season. Gray tells Denton that he thinks he’ll be able to return about 10 or 11 games into the season, since Opening Day IL stints can be backdated by three days. The Cards have a scheduled off-day after their eighth game on the docket.

While it’s not ideal for a club’s ace and key offseason signee to begin the year on the shelf, it seems Gray is planning on a minimal stay that will only involve missing a couple of turns through the rotation. Gray posted a 2.79 earned run average for the Twins last year, finishing second to Gerrit Cole in American League Cy Young voting.

As the Cards were looking to remake their rotation on the heels of a disaster season, Gray was the centerpiece of their offseason. While Lance Lynn and Kyle Gibson were signed to serve as veteran innings eaters, Gray was given a three-year, $75M deal to be at the front of the rotation for the foreseeable future.

Gray’s temporary absence will open a rotation spot for a little while behind Miles Mikolas, Steven Matz, Lynn and Gibson, with Thompson stepping into it. He has a 3.65 ERA in 101 career innings to this point in his career. His 23.4% strikeout rate, 9.2% walk rate and 47.3% ground ball rate are all fairly close to league average. This spring, he has a 2.81 ERA in 16 innings.

He has an option year remaining and could perhaps be sent to Triple-A when Gray is healthy, but Liberatore has an option as well. That could perhaps leave Thompson in a long relief role while Liberatore is the one to go to Triple-A, depending on how the Cards want to play it.

As for Nootbaar, he injured himself making a catch a couple of weeks back and was diagnosed with two nondisplaced fractures in his ribs. Since Tommy Edman is also going to start the season on the shelf, the Cards will be without two thirds of their planned starting outfield. Edman has still been experiencing pain in his surgically repaired right wrist.

Until Nootbaar and/or Edman are able to return, the Cards will likely roll with an outfield of Dylan Carlson in center while Jordan Walker and Alec Burleson take the corners. Utility player Brendan Donovan will be rotating through multiple infield and outfield positions. Prospect Victor Scott is still in camp but the club could prefer for him to have regular playing time in the minors as opposed to a big league bench job, which could lead to Michael Siani making the roster. There are also plenty of guys shaking loose from other clubs as roster cuts are made and veterans opt out of minor-league deals.
