SPEARFISH, S.D. – Black Hills State University head track and field coach, Seth Mischke, has announced the signing of Sully Mack to join the Yellow Jackets in the 2019-20 season.

Mack is a 6-2 thrower from Watertown, South Dakota. He is a four-time conference champion at Watertown High School, and has placed at state twice in the discus and once in the shot put. During Mack's senior year, he won both indoor and outdoor conference in discus, placing second at state. He was fourth in shot put in the conference, and sixth at state. He was named the team field MVP after both his junior and senior years.
 
"Sully will be a great addition to our team next year. He had an outstanding high school career at Watertown High School. He is extremely athletic and will excel at the two new events (javelin and hammer/weight throw) at the collegiate level to go along with his shot put and discus," said coach Mischke. "We were really looking to round out our recruiting class on the men's side, and Sully was a fortunate find for us. We are excited to have him as a Yellow Jacket!"
 
Sully is the son of Terri and Neal Mack. His older sister (Jenni) and older brother (Cullen) threw at SDSU. Sully plans to major in elementary education at BHSU.
