What happened: A debate over home fans cheering an opposing player is part of the Mets conversation before the game begins. New York is 0-0 at scheduled first pitch.

Why it matters: The issue centers on crowd etiquette rather than any change to the on-field situation. For the New York Mets, the only confirmed game state so far is a 0-0 start.

What to watch: Watch for first pitch and the first on-field development once play begins.
