Supporters of Pope Leo XIV gathered Saturday, not in a cathedral or a church, but a baseball stadium the pope once frequented years as Robert Francis Prevost.

Pope Leo, a native of Chicago's south side and a long-time fan of his beloved but beleaguered White Sox, sent a video message on Saturday to a sellout crowd attending Catholic Mass in his honor at their hometown ballpark.

You are the promise of hope for so many of us,” the pope told young people attending the event at Rate Field, the home of the Chicago White Sox baseball team.
