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.

CHICAGO (AP) — The Chicago White Sox plan to unveil a graphic installation on Monday that honors Pope Leo XIV. Robert Prevost became the first pope from the U.S. in the history of the Catholic Church when he was elected on May 8. The Chicago-born missionary, who took the name Leo XIV, is a White Sox fan, according to his brother, John.
