What happened: The Phillies fired off a playful 'How 'bout them apples?' post tagged #RingTheBell, aimed at division rival the Mets. The message landed amid the back-and-forth between the two NL East clubs and their fan bases.

Why it matters: It's the latest jab in the long-running Phillies-Mets rivalry, one of the more heated in the National League East. Social needling like this keeps the rivalry simmering between matchups and feeds the engagement both fan bases thrive on.

What to watch: Watch for the Mets' on-field and online response, and for the next chapter when the two clubs meet again.
