What happened: Jazz Chisholm Jr. homered in the Yankees' win Sunday while swinging Aaron Judge's bat. This time he made a key adjustment to his swing, a change aimed at avoiding the kind of injury that struck the last time he used the bat. In his most recent regular-season game swinging Judge's bat, Chisholm strained his oblique.

Why it matters: The production matters with Aaron Judge sidelined, leaving New York short on power. Chisholm tapping into Judge's bat — safely this time — gives the lineup a needed lift while it waits on its injured star.

What to watch: Watch whether Chisholm keeps using Judge's bat and stays healthy, and how the Yankees' lineup holds up until Judge returns.
