Majors Baseball (10-11-12)
The 10-11-12 All Stars had an amazing run deep into the District 9 tournament. After losing a close first round game to the eventual champions, the MI All Stars fought their way back through the losers bracket - winning several games in dramatic come-from-behind fashion - before settling for a third place finish.
