One of the most successful softball coaches in Arizona high school history, Jerry Mullin, announced his coaching retirement today after 38 years of leading the Seton Catholic Preparatory softball program. Mullin arrived at Seton Catholic, located in Chandler, Ariz., in 1985 and took over the softball program for the 1986-87 school year, transforming it into a small-school powerhouse by the mid-1990s. He won 10 AIA State Championships over a 15-year span from 1996 to 2010, including two periods of four consecutive state titles (1996 to 1999 in Class 2A and 2002 to 2005 in Class 3A). Mullin was a perfect 10-0 in state championship games.
