Our Mission:
  • Provide Mercer Island's most talented 8-12 year olds opportunities for higher level skill development and competition.
  • Create a well rounded baseball player. Develop physical, mental and emotional skills as well as teach fundamental game strategies.
  • Prepare our kids to play competitive baseball after age 12.
  • Provide the MI community (kids and families) with a unique on-island opportunity to support and celebrate Mercer Island baseball.

Mercer Island Select Baseball will begin scheduling games for the spring/summer 2012 season soon.  Please email our competition committe at to send your contact information. 

We typically have 8 teams each season:

9U Thunder/Lightning

10U Thunder/Lightning

11U Thunder/Lightning

12U  Thunder/Lightning

The Thunder teams typically play the highest level of competition while the Lightning teams play at a slightly lower skill level but are still very competitive.

Founded in 2006 as the Mercer Island Travel Team and renamed Mercer Island Select Baseball club, we are a select baseball progam for kids that live on Mercer Island, Washington aged 8-12.  All of our kids are required to play in the Mercer Island Little League program.  More...
