Zack Wheeler and his wife Dominique are expecting their fourth child, prompting the Philadelphia Phillies to adjust their pitching rotation. Wheeler was set to start against Toronto but will be replaced by Cristopher Sanchez, Mick Abel, and Jesus Luzardo for the series. The Phillies, currently on a four-game losing streak, hope to boost their lineup with the return of Bryce Harper after his injury, though facing a Blue Jays team in strong form presents a challenge.
