What happened: Hunter Dobbins was added as the 27th man for the Cardinals' active roster. Bruce Zimmermann had his contract selected from Triple-A Memphis, while Ryan Fernandez was optioned to the minors.

Why it matters: Navigating 18 innings in a single day requires substantial bullpen depth to avoid overtaxing relievers. Max Rajcic was transferred to the 60-day injured list with a right elbow issue to clear 40-man roster space for the additions.

What to watch: Managerial strategy will be tested to distribute pitcher workloads efficiently across both matchups.
