What happened: Jackson Merrill made a leaping catch at the outfield wall to rob Christian Yelich of extra bases. The defensive highlight erased a major scoring threat.

Why it matters: Run-saving catches are critical in October, and Merrill's defensive range changes how opponents can attack the outfield gaps. Eliminating extra-base hits often determines the outcome of tightly contested postseason games.

What to watch: Watch for both players to remain focal points as the National League Division Series continues.
