Rate Field will host citywide Mass honoring Pope Leo XIV, the Archdiocese of Chicago announced. On Monday, a graphic installation will be unveiled at the ballpark at the location where the future pope cheered in Game 1 of the 2005 World Series.

The Cubs initially claimed Pope Leo as one of their fans on the Wrigley Field marquee, but his brother, John Prevost, has since confirmed that he roots for the White Sox, whose World Series win over the Astros in 2005 was their first championship since 1917.

A celebration of the election of Pope Leo XIV, the first pope born in the United States and Chicago, will be held at Rate Field in June.
