Alex Bregman’s move to Boston fuels a high-stakes September sprint for the Red Sox, turning the month into a postseason warm-up. His playoff streak, unmatched since his first full season in 2017, becomes the focal point of Boston’s bid to stay in the AL wild-card race as the lineup and clubhouse cohere around his leadership and relentless preparation.

Devers’ exit to San Francisco creates a slugging void the rest of the lineup must fill, while Bregman’s presence—a mix of veteran poise and competitive fire—helps the Sox chase October. The rotation and bullpen—Bello, Crochet, and Giolito at the top—shape their path, with the city’s energy and the history of Red Sox playoff runs adding pressure and pride to every September pitch.
