Go Sister MoJo!

Sister Mary Jo Sobieck, OP

Sister Mary Jo Sobieck, OP, is all about being real. She is whom God has called her to be, vowed religious, teacher, and, as her first pitch at a White Sox game in August of 2018 proved, skilled athlete. At first, the roles may seem somewhat incongruous, but Sister Mary Jo said ‘yes’ to all of them, believing each allows God to work through her. Even as a pitcher on the mound at Guaranteed Rate Field!

As the youngest of ten children growing up in Minnesota, Sr. Mary Jo was always active. She began playing sports in fifth grade and was a three sport athlete (basketball, softball, and volleyball) at Cathedral High School, graduating in 1987. She then played softball and volleyball at Vermilion Community College before finishing her athletic career at The College of St. Scholastica in Duluth. At 25, Sr. Mary Jo became a member of another “team,” the Dominican Sisters of Springfield, Illinois, which ultimately led to an assignment at Marian Catholic where she has taught theology since 2007.

Following her viral moment on the mound, Sister rounded the bases of her own Field of Dreams. Her travels took her to New York City where she appeared on Fox & Friends and Inside Edition, Nashville, Tennessee for a segment on Picker and Ben, and Los Angeles where she matched wits with elementary students on Nickelodeon’s “Are You Smarter than a Fifth Grader?” A commemorative bobble head soon followed as well as an Allen & Ginter TOPPS baseball card made in her honor. Perhaps Sister’s greatest surprise was her ESPY Award nomination in the Most Viral Sports Moment Category. Although she did not win, she experienced many ‘red-carpet’ moments!

While saying “yes” to an unexpected invitation thrust Sister Mary Jo into the spotlight, it also allowed her to use her gifts to share  the message of the Gospel and bring people closer to God. It is something she does with her students at Marian Catholic every day as she helps them live their passion. "Do your best, and let God do the rest." 


Where it all began

Few could have foreseen the media frenzy that occurred after Sister Mary Jo threw out the first pitch at the White Sox game on August 18, 2018.


The Chicago White Sox even called it "One of the most impressive first pitches of all time."


Two days later, on Monday, August 20, the media frenzy began...

And it has not slowed down since!
