Head of Pitching

League is a 10-year MLB veteran baseball pitcher with invaluable experience pitching for the Toronto Blue Jays, the Seattle Mariners, and the Los Angeles Dodgers. After a record season with the Seattle Mariners, where he earned 37 saves, League became a 2011 member of the AL MLB All-Star Team. 

Throughout League’s career, he had the honor of pitching and developing as an athlete in the company of the best in the business, from nationally recognized coaches to Hall of Fame pitchers. 

League has also worked with the best physical therapists, movement specialists, sports psychologists, neuro-linguistic programming master practitioners, and mental coaches in the country. 

Like most elite athletes, League faced adversity in his professional career. He understands what it’s like to be injured, have surgery, and teach yourself how to move all over again. In the process of rehab and recovery, League gained an even deeper understanding of body mechanics, functional strength, and mental strength.
