Both sub-.500 clubs (Phillies 19-22, Red Sox similar) enter with mediocre recent form—Philly won two straight over Colorado before the opener, while Boston dropped three of its last five, including a 4-1 loss to Tampa Bay. Red Sox catcher Willson Contreras is probable despite a hand contusion; Phillies pitchers like Zach Pop (calf) remain sidelined on the 15-day IL, but core lineup intact amid interleague play.

Both sub-.500 clubs (Phillies 19-22, Red Sox similar) enter with mediocre recent form—Philly won two straight over Colorado before the opener, while Boston dropped three of its last five, including a 4-1 loss to Tampa Bay. Red Sox catcher Willson Contreras is probable despite a hand contusion; Phillies pitchers like Zach Pop (calf) remain sidelined on the 15-day IL, but core lineup intact amid interleague play.
