Phillies reactivating pitcher Ranger Suárez for Sunday's game, potentially altering team roster.

The Philadelphia Phillies are set to reactivate pitcher Ranger Suárez, who's recovering from back stiffness, for a start on Sunday against the Arizona Diamondbacks. Suárez's return could prompt the team to shift to a six-man rotation or move Taijuan Walker to a relief role due to concerns about his sustainability as a starter. The Phillies hope Suárez's experience can help stabilize the team's performance.
