Bryce Harper and J.T. Realmuto both homered in the first inning to back Aaron Nola, who allowed just one run over seven innings, as the Phillies topped the Reds 5-1 on Opening Day at Citizens Bank Park. Harper's two-run blast came off Hunter Greene in the first, while Realmuto's solo shot was off Alexis Díaz. Nola struck out eight and walked one to earn the win in his first start as a Phillie.
