Toronto Blue Jays rookie pitcher Trey Yesavage, the team's No. 1 prospect, made his first World Series start on October 25, 2025, against the Los Angeles Dodgers. Despite not having his best splitter, Yesavage opened the game with a strikeout of Shohei Ohtani, nearly blowing the roof off Rogers Centre. He aimed to strike out everyone he faced and managed to limit the Dodgers to two runs over four innings, facing numerous bases-loaded and key situations. Notably, he became the second-youngest pitcher to start Game 1 in World Series history at 22 years and 88 days. Yesavage struggled with his splitter after the first inning, relying more on fastballs and sliders, which the disciplined Dodgers hitters capitalized on, including an RBI single by Mookie Betts and a home run by Daulton Varsho. Despite the mixed performance, Toronto's offense exploded with a nine-run sixth inning, including a historic pinch-hit grand slam by Addison Barger, the first in World Series history. Yesavage expressed pride and acknowledged the nerves of his debut, which he said was a memorable experience. The game ended with an 11-4 victory for Toronto, and Yesavage's performance marked a significant moment for the young pitcher and the Blue Jays in their quest for a World Series title.
