On Thursday afternoon -- running with a claim by an ABC News reporter -- the Chicago Cubs boasted that Pope Leo XIV was a fan of theirs, with their famous signage outside Wrigley Field telling the locals the good news: "Hey, Chicago. He's a Cubs fan!"

John Prevost, Pope Leo's older brother, confirmed his MLB allegiance in multiple interviews, putting to rest the debate between the North and South Side.

One of the debates swirling around Pope Leo XIV’s papacy doesn’t deal with religion at all. Instead, it deals with sports, specifically the debate on whether someone born in Chicago roots for the Cubs or the White Sox.
