Where are the games played?

Games are played on Mercer Island (typically Homestead or South Mercer) and off-Island.  Our softball teams play in interlocked leagues with teams from District 9 (the Eastside).  Away games will be played at different locations on the Eastside, but most frequently in Bellevue.

What times are the games played?

Weeknight games typically start at 6pm.  Weekend game times vary depending on field availability.

When are practices?  Can I request a specific time?

Coaches select their specific practice day, time and location.  Practices are once a week for AA and typically twice a week for AAA, Coast, Majors and Juniors.  One of those practices is batting cage time at South Mercer or PEAK.  Registrants cannot request a specific practice day/time/location.

How are teams formed?

Typically, we don’t have more than two teams at a level.  We generally split to balance the talent among the teams although the MIBGC and MILL board have some discretion in the process.

How do I figure out my daughter’s league age?

Softball League Age is determined by your daughter’s age as of December 31st.  For example, if your daughter turns 10 on December 31st, they are league age 10.  If your daughter turns 10 on January 1st, they are league age 9.  There are no exceptions to this rule.   Please review the Little League Age Chart to confirm your child’s League Age.  Baseball has a different League Age cutoff.
