Cardinals face injury uncertainty leading up to Opening Day

Top Cardinals starter Sonny Gray exited today’s spring start with a trainer in the middle of an at-bat against Washington’s Nick Senzel. The team announced shortly afterward that Gray was experiencing tightness in his right hamstring. Gray declined to comment on the potential injury after exiting, instead stating that he wanted to talk to the team’s training staff and learn more about the issue before speaking with the media (link via Derrick Goold of the St.  Louis Post-Dispatch). Gray missed roughly a month of the 2022 season with a strain in that same right hamstring as a member of the Twins back in 2022. Goold further tweets that Gray is headed for an MRI to determine the severity of the issue.

An absence of any real note would be a nightmare scenario for the Cardinals. While the Cards overhauled their rotation this winter, Gray is the lone front-of-the-rotation arm the team brought in. Lance Lynn isn’t far removed from posting high-end results himself, but he’s 36 years old and coming off arguably the worst season of his career. He, like fellow mid-30s veteran Kyle Gibson, was signed more as a durable source of innings than to be a clear playoff-caliber starter.

Gray, 34, is fresh off a Cy Young runner-up finish in the American League. He pitched 184 innings of 2.79 ERA ball last season, fanning 24.3% of his opponents against a 7.3% walk rate. Gray’s 2.83 FIP was a near-identical match with his ERA, though metrics like xFIP and SIERA, which normalize home run rate, were more bearish and pegged him in the mid- to upper-3.00s. Gray’s 5.2% homer-to-flyball ratio was less than half the 12.3% career mark he carried into the 2023 campaign. The Cardinals signed him for three years and a total of $75MM back in November. He’s slated to be joined by Gibson, Lynn, Steven Matz and Miles Mikolas in one of the game’s oldest rotations.

Even if Gray can’t quite replicate his 2023 performance, he’s the clear top starter on that St. Louis staff. Were he to miss time, the drop-off between Gray and his replacement would be substantial. At present, the top options to step into the staff in his stead would presumably be lefties Matthew Liberatore, Zack Thompson and Drew Rom. Righties Sem Robberse and Adam Kloffenstein are both on the 40-man roster as well, though neither has made his MLB debut yet.

The Cardinals, at least thus far, haven’t brought in any veteran big-league starters on non-roster deals. That’s understandable, as most players open to that type of deal would take a look at the veteran rotation in St. Louis and see a lack of opportunity — but the lack of any proven depth could also be an issue in 2024, depending on how the rest of the staff holds up.

Gray isn’t the only key member of the Cardinals who’s facing some health-related uncertainty. Tommy Edman, formerly the team’s shortstop and now slated to serve as the Cardinals’ everyday center fielder, isn’t recovering from arthroscopic wrist surgery as swiftly as the team hoped. Katie Woo of The Athletic reports that “internal concern is growing” that Edman might not be ready for Opening Day. Edman still hasn’t been cleared to face live pitching, Woo writes, and despite the fact that Opening Day is just over three weeks away, there’s not even a timetable for when that might happen.

Fourth outfielder Dylan Carlson would step into the starting job in center field if Edman is on the injured list to begin the season, per the report. Lars Nootbaar played plenty of center field last season, but perhaps if the plan is for him to play left field regularly when Edman is healthy this season, the team simply wants Nootbaar to get as many reps in that position as possible. Carlson’s role as a fourth outfielder would be cycling through all three spots anyhow.

Edman, 28, had a disappointing 2023 at the plate while playing through pain in that now surgically-repaired wrist for much of the season. The versatile switch-hitter spent nearly a month of the ’23 season on the injured list due to inflammation in that wrist, and when he was healthy his output at the plate dropped from .265/.324/.400 in 2022 (106 wRC+) to just .248/.307/.399 in 2023 (92 wRC+).

In the event that Edman indeed requires a stint on the injured list to begin the season, that’d open up a spot on the bench for the Cards. That wouldn’t necessarily need to be an outfielder, as utilityman Brendan Donovan is no stranger to the outfield, and as previously noted, Nootbaar can handle center field work as well. That said, an outfielder would be the most logical candidate. Lefty-swinging Michael Siani and Alec Burleson are both on the 40-man roster already and both have minor league options remaining. Siani is regarded as a plus defender in center field and would offer premium speed off the bench, while Burleson would be limited to first base and the corners but give the Cards some power that the bench currently lacks.
