What happened: Colorado's Jake McCarthy turned a leadoff at-bat into an inside-the-park home run, sprinting through all four bases before the throw could get home. The Rockies spotlighted the play for McCarthy's flat-out hustle, citing his home-to-home time and top sprint speed.

Why it matters: Inside-the-park home runs are among the rarest results in the modern game, and they hinge on elite speed rather than power. McCarthy's burst underscores why his legs remain one of Colorado's most usable offensive weapons at the top of the order.

What to watch: Watch whether McCarthy keeps batting leadoff and how often Colorado can turn his speed into extra bases the rest of the homestand.
