Sister Mary Jo Sobieck of Chicago threw out a perfect pitch at the Chicago White Sox Game on Saturday. Mary Jo threw out the first pitch at the game versus the Kansas City Royals...and it was pretty amazing! Many are saying Chicago has another local nun to celebrate after Sister Jean of Loyola helped garner lots of excitement for the school's NCAA run. Sister Mary Jo helps works at Marian Catholic High School in Chicago Heights, Ill. and used to play volleyball and softball growing up. It seems her athleticism paid off! Watch the video of her pitch below and check out footage of her practicing for the big day!
