What happened: According to reporter Jon Heyman, onlookers inside the Philadelphia food hall greeted the visitor with widespread thumbs-down gestures on Tuesday. Heyman noted that walking into the local venue wearing the rival outfielder's apparel required significant nerve.

Why it matters: Soto, who was selected to bat second for the National League in the All-Star Game, represents a major antagonist for Philadelphia fans as a star outfielder for the division-rival New York Mets. Meanwhile, New York Yankees slugger Ben Rice faced similar vocal hostility from local spectators during his first-round exit at Monday's Home Run Derby.

What to watch: Both Soto and Rice will face the Philadelphia crowd again when the National League and American League square off in Tuesday night's All-Star Game.
