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.

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.
