Sister Jean — the world-famous Loyola University Chicago men’s basketball mascot and spiritual coach — soon will have good company — and some major competition — among sports-related bobbleheads.

The National Bobblehead Hall of Fame and Museum in Milwaukee said it plans to go into immediate production on a new bobblehead featuring Sister Mary Jo Sobieck of Marian Catholic High School in Chicago Heights.

Sister Mary Jo threw out the first pitch at a Chicago White Sox game at Guaranteed Rate Park on Saturday. Her ceremonial first pitch went right over home plate. Experts said it would have been called a perfect strike had the game been underway.

The White Sox immediately tweeted “one of the most impressive first pitches of all time.”

A video of the extraordinary pitch also quickly went viral, prompting the decision by the National Bobblehead Hall of Fame to commit to a new Sister Mary Jo bobblehead.

That Sister Jean bobblehead broke all kinds of records when it went on sale soon after the Loyola Chicago men’s basketball team went deep into the NCAA men’s basketball tournament last spring — to the surprise and delight of tens of thousands of fans.
