What happened: The Chicago Cubs shared a lighthearted social welcome to new additions around the club. It lands amid a season in which Chicago has repeatedly turned to late-inning heroics, walking off opponents for an MLB-leading total this year.

Why it matters: Walk-off wins are a marker of a resilient clubhouse and a deep bullpen-and-bat combination that can flip games in the final frame. For a Cubs team chasing position in the National League, those one-run, last-at-bat results compound in the standings and in momentum heading into the second half.

What to watch: Watch whether the Cubs keep converting in the late innings as the schedule tightens and the playoff picture sharpens through the summer.
