The Philadelphia Phillies bolstered their bullpen by acquiring reliever Carlos Estevez and are predicted to compete for his re-signing despite high competition and expected cost. They secured their first National League East title in over a decade, driven by a strong bullpen and standout performances, including a breakout season from Cristopher Sánchez. Meanwhile, the Boston Red Sox aim to address bullpen deficiencies and starting rotation needs, with potential targets including Tanner Scott and Walker Buehler. The Washington Nationals faced setbacks with injuries to key pitchers but found an unexpected contributor in rookie Mitchell Parker. Additionally, the St. Louis Cardinals may pursue left-hander Sean Manaea to strengthen their rotation, while the Houston Astros consider re-signing Yusei Kikuchi, who has expressed his desire to stay and win a championship with the team.
