Through a combination of technology, experienced coaches and data collection we assess, monitor, and progress our athletes on a weekly basis to meet the individual goals and aspirations of each RAS athlete. By understanding your personal biomechanical signature and the functional ability of your body, we build a comprehensive roadmap for success by enhancing your sport specific strength and skill. Since every athlete is unique, we do not take a one size fits all approach. Every athlete receives a custom performance plan tailored to their goals, needs, schedule, and physical abilities.





Casey Upperman
Casey Upperman
Founder/Owner/Performance Coach

Born and raised in Phoenix, Casey fell in love with the game of baseball when he was five years old. After attending Notre Dame Prep in Scottsdale, Arizona, he was selected by the Atlanta Braves in the 2009 MLB Draft. Forgoing his commitment to University of Arizona, he decided to attend Yavapai College to have the ability to enter the Draft the following year. He was selected by the Arizona Diamondbacks in the 2010 MLB Draft and signed his first professional contract. Playing Professionally from 2010-2017, he spent time with the Arizona Diamondbacks, Washington Nationals, and Baltimore Orioles. As his playing career was winding down due to durability and injury issues, he decided that there had to be a better way to help pitchers reach their goals and have more control of their future and dreams. After spending four years in Los Angeles with Dr. Tom House and the National Pitching Institute, he realized that there is a tangible, data driven alternative to rotational athletic training that starts with the player understanding how to be their own best coaches and building a process that works for them. Since then, Casey has become a Certified Pitching Instructor through the National Pitching Association, a Titleist Performance Institute Certified Instructor, OnBaseU Certified Pitching Instructor, along with serving as varsity pitching coach at Notre Dame Prep (2014-2018) and assistant varsity coach at Cactus Shadows High School (2018-Present). He currently lives in Phoenix with his two dogs, Fitz and Floyd.
