What happened: The "South Side" era for Braden Montgomery officially begins as the top-tier prospect has been called up to the major league roster. Montgomery, the primary return in the trade that sent Garrett Crochet to Boston, is set to make his debut after tearing through the minor league ranks this season.
Why it matters: This promotion marks a pivotal moment for the franchise's rebuild, placing their most significant trade asset in the heart of the lineup. Montgomery's switch-hitting power and elite arm strength provide an immediate athletic upgrade as the team evaluates its long-term core.
By the numbers: Montgomery arrives in the majors having hit 16 home runs in the minor leagues this season, including a dominant stretch in Triple-A Charlotte. His 2026 stats featured a .314 batting average and a 53.8% hard-hit rate, underscoring the elite bat speed that made him a top-25 global prospect.
What to watch: Montgomery is expected to start in right field for tonight's series opener against the Atlanta Braves. The debut marks the final arrival of the four-prospect package received in the Crochet deal.
