What happened: Chicago White Sox rookie Braden Montgomery walked through his plate approach on MLB Network, describing how he studied the pitcher's repertoire, laid off pitches down and away, and stayed ready for the fastball. He recounted that mindset just before he connected on a walk-off home run in his MLB debut.

Why it matters: The debut homer capped the arrival of Braden Montgomery, the headline return from the Garrett Crochet trade. His disciplined approach offers a window into the poise the rebuilding White Sox are banking on from their top prospect.

What to watch: Watch how Montgomery holds that same discipline through his first full series as opposing pitchers adjust to him.
