The Philadelphia Phillies are facing a significant pitching dilemma as Taijuan Walker continues to struggle, with the team losing nine consecutive games when he starts. Speculation grows that Walker's recent performance could lead to his release or demotion, raising questions about who would take his place in the rotation, with options like Kolby Allard and Tyler Phillips showing mixed results. Meanwhile, teams across MLB are preparing for the September 1 roster expansion, which allows for two additional players, often including a position player and a pitcher. In notable moves, the Boston Red Sox have called up veteran pitcher Rich Hill for his 20th season, making him the only active player to achieve this milestone if he plays. Additionally, former Clemson pitcher Ryan Miller has been promoted by the Los Angeles Angels, poised to make his major league debut after a strong season in Triple-A. The landscape of MLB is shifting as teams make critical roster decisions heading into the final stretch of the season.
