SJMSBL Champions
* In 2012 the league went through division realignment and honary renaming. The National division was renamed Dunn after founder and former President Ron Dunn. The American and Pacific divisions merged to form the Ettare division in honor of longtime manager and board member Robert Ettare. The Atlantic division was renamed Nicewonger after former Umpire in Chief Dave Nicewonger who lost his battle with cancer in March 2011.
