Cardinals right-hander Sonny Gray has been diagnosed with a “mild” strain of his right hamstring, president of baseball operations John Mozeliak announced Tuesday morning (X link via Derrick Goold of the St. Louis Post-Dispatch). While Mozeliak called it “encouraging” news that Gray had dodged a more serious strain, he acknowledged that it could be “challenging” to get Gray ready for the beginning of the season and that Opening Day is now “in question” for the team’s top offseason acquisition.
Gray missed time with a pair of strains in this same hamstring as a member of the Twins back in 2022, though Mozeliak told reporters today that the team is confident this is less severe. It’s a mild enough issue that Mozeliak has already spoken out against the possibility of Gray’s injury spurring further additions on the starting staff (X link via John Denton of MLB.com).
“I definitely feel it’s not something that is required at this point,” Mozeliak said when asked about potentially bringing in some additional help for the rotation. “Obviously if something changes, we’d have to look at it differently, but we’re not thinking we’ll have to do anything now.”
The Cardinals haven’t spoken with the Boras Corporation about either Blake Snell or Jordan Montgomery recently, and a “mild” injury for Gray would’ve been an unlikely catalyst for such a major response anyhow. Mozeliak’s comments make it unlikely that remaining second-tier arms like Michael Lorenzen and Mike Clevinger will be considered, though it’s possible the Cards could look to add some modest depth either via waivers or perhaps with a minor league deal for a veteran who’s amenable to a non-guaranteed pact.
With Gray presumably on the shelf to start the season, the Opening Day nod feels likelier to fall to veteran Miles Mikolas. He’d be followed by lefty Steven Matz and righties Lance Lynn and Kyle Gibson, both of whom signed a one-year contract in free agency this past offseason. (Matz is entering the third season of a four-year, $44MM free agent deal himself.) The top in-house options to step into the fifth starter spot, if needed, are lefties Matthew Liberatore and Zack Thompson. Fellow southpaw Drew Rom made eight starts for the Cards last season but struggled to an ERA north of 8.00 in the process.
The Cardinals signed Gray to a three-year, $75MM contract this offseason and forfeited their second-highest draft pick as well as $500K of space from next year’s international bonus pool in order to do so. He’d already been tabbed the team’s Opening Day starter. Gray finished second to Gerrit Cole in American League Cy Young voting last season after giving the Twins 184 innings of 2.79 ERA ball through 32 starts. He fanned 24.3% of his opponents against a 7.3% walk rate.
The Cardinals, meanwhile, posted the fifth-worst ERA in baseball at 5.08 — a number that includes 21 starts from Montgomery (3.52 ERA) and 20 from Jack Flaherty (4.43 ERA) — both of whom were traded at the deadline. The trio of Gray, Gibson and Lynn was signed in large part to provide some stable veteran innings, though Gray obviously comes with a front-of-the-rotation ceiling as well. For now, his ability to lead the staff will be placed on hold, but if it’s a short enough absence there’ll still be time for Gray to perhaps make 30 starts for the Cards when all is said and done.
Donaldson, now 38, took a winding path to the major leagues and was a late bloomer, but he nonetheless reached incredible heights as a big leaguer once everything aligned.
His first season in Toronto would eventually prove to be the best of his career. He launched 41 home runs and slashed .297/.371/.568 for a wRC+ of 154. The Jays won the A.L. East that year and Donaldson launched another three home runs in that year’s playoffs as the Jays advanced as far as the ALCS. He was graded as worth 8.7 fWAR and was voted as that year’s A.L. MVP, just ahead of 
Donaldson bounced back tremendously with Atlanta, getting into 155 games, walking in 15.2% of his plate appearances and hitting .259/.379/.521 for a 131 wRC+. He then rejected a qualifying offer from Atlanta and then signed a
