TMYBA Parents and Players - 

We hope you are enjoying baseball and softball in Mequon/Thiensville!   As we approach the ‘later innings’ of the 2017 season, we want to thank you for your participation and offer a few reminders of some events coming up.  First, we appreciate the participation and enthusiasm of all who took part in the Family Fun Before the 4th parade and All-Star games.  We had great weather and great fun on Saturday!  And a BIG thanks to all our parent coaches who have shared their time and effort to make this season a success.  The TMYBA family knows how much you do and we are grateful!!

The Rookie Baseball and Rookie Softball seasons have come to an end.  There were no TMYBA events on Monday 7/3 and Tuesday 7/4 due to the holiday.  Games resume on 7/5, and playoffs for the remaining leagues start on 7/10.  Weather permitting; the 2017 TMYBA baseball and softball seasons will end by 7/14.  

Last, HEAT tryouts for baseball and softball have been announced.  Please register online prior to tryouts.
