The Seattle Elite Baseball League was founded in 2010, starting play in the summer of 2011 with a 12-team 16U league. In 2012, the SEBL expanded to four leagues of 12 teams each, spanning the ages of 14-18. 2013 saw more expansion, with a 13U league starting up along with more teams being added to the four older age groups. For 2014, the Seattle Elite League will continue to grow, adding teams at each of the five age groups (13U - 18U).
