What happened: MLB Network's #MLBCentral highlighted a visible change in Pete Crow-Armstrong's swing mechanics, contrasting his current form with how he looked in March. Mark DeRosa broke down the Cubs outfielder's swing decisions on air following a two-homer game.

Why it matters: The segment lands during a stretch in which Chicago has leaned on Crow-Armstrong as a key offensive contributor while the Cubs weigh additions ahead of the trade deadline. A cleaner swing path could matter for a lineup the front office is still shaping for a playoff push.

What to watch: Watch whether the mechanical tweak holds up as Chicago approaches the trade deadline and the stretch run.
