MIAMI — The Miami Heat promoted two internal staffers to lead the Sioux Falls Skyforce, the franchise’s NBA G League affiliate, naming Mario Casamajor head coach and Liam Doyle general manager.
Casamajor becomes the 23rd head coach in Skyforce franchise history. He enters his sixth season with the Heat organization after spending the previous three seasons as Head Video Coordinator. He joined Miami as a Video Room Intern ahead of the 2021-22 season and spent two seasons in the video room before earning the promotion to lead the video staff, supporting coaches through video analysis, game planning and player development.
Before joining the Heat, Casamajor spent three seasons in basketball operations with the Minnesota Timberwolves and their G League affiliate, the Iowa Wolves. He also spent one season with the Windy City Bulls. Casamajor worked as a video coordinator with USA Basketball from 2017-21, including the United States’ gold-medal run at the 2020 Tokyo Olympics. In 2026, he was named Head Coach of the Nicaragua Men’s National Team and Program Director for the Nicaragua Women’s National Team.
The Illinois native began his coaching career as an assistant coach at his alma mater, St. Patrick High School in Chicago, while also coaching the Mac Irvin Fire AAU program on Nike’s EYBL circuit. Casamajor earned his bachelor’s degree in political science from Eastern Illinois University.
Doyle most recently served as Senior Manager of Basketball Analytics and Scouting for the Heat and Assistant General Manager of the Skyforce. In his role with Miami, Doyle provided data analysis and scouting metrics to help the basketball operations department enhance team performance. He began his career with the Heat as a Basketball Analyst ahead of the 2019-20 season and was promoted twice — first to Basketball Analytics Manager, then to Senior Manager of Basketball Analytics and Scouting. Prior to joining Miami, he spent one season as a Data Science Intern with the Oklahoma City Thunder.
A native of Albany, New York, Doyle earned his bachelor’s degree in physics from Rensselaer Polytechnic Institute in 2015 and an MBA from the University at Albany in 2018.
Both Casamajor and Doyle are expected to begin their new roles ahead of the Skyforce’s upcoming G League season.
