Montero, 25, makes his season debut after Verlander was scratched due to age‑related symptoms and placed on the 15‑day IL. He posted a 9.00 ERA and 1.80 WHIP in two spring‑training starts, but the Tigers expect a fresh start.
Opposing him is Cardinals right‑hander Kyle Leahy, who went 0‑1 with a 7.20 ERA in his first start of the season. The game will be broadcast on Peacock/NBC Sports Network and MLB.TV.
