NASCAR announced promotions Thursday for some of its officials.

Also, John Bobo has been promoted to Vice President, Racing Operations. Scott Prime has been promoted to Vice President, Strategic Development.

Stefanyshyn takes over the role Jim Cassidy held for three months before leaving the organization. Cassidy had been promoted from his position of Vice President, Racing Operations, a position now filled by Bobo.

Stefanyshyn joined NASCAR in May 2013 and helped shaped NASCAR’s approach to competition. He will continue to report to Steve O’Donnell, NASCAR’s Executive Vice President and Chief Racing Development Officer

Probst, who joined NASCAR in 2016 after two decades of industry experience, will be responsible for leading the sport’s efforts toward enhancing competition and integrating innovation and technology across the sport’s at-track operations. He will report to O’Donnell.

“John was instrumental in the development of our new inspection process, incorporating best in class technology and technology partners into one of our most important competition operations,” O’Donnell said in a statement. “Integrating new, relevant technology into our operations and innovating our racing product are strategic priorities for us and John is well suited to continue the important leadership of this area.”
