Leon Grunalt began his softball career in 1955 on a local fast pitch team. After developing a love for the game, he began his managerial career with local Detroit teams. After several successful seasons within local travel leagues, Grunalt found success in 1984 when his Budweiser sponsored team won the ASA Men’s 35 and over National Invitational. After ASA sanctioned this category in 1985, Grunalt’s team went on to win the National title for two consecutive years. Then, in 1988, Grunalt joined forces with Karl and Fred Nothdurft and with new sponsorship the Nothdurft slow pitch team was created. Under his leadership, the team won 37 consecutive games, compiled a record of 63-5 in national championship play and earned seven National titles. Grunalt managed nine ASA Slow Pitch National Championship teams before retiring in 1994. Grunalt has been a member of the Metro Detroit ASA Hall of Fame since 1994. Grunalt passed away on December 12, 2015.
