Mike’s Memorial Baseball League (MMBL) is aware that several youth baseball associations have announced or are planning to announce they are changing to a new wood-like bat standard in 2018 (marked with a USA Baseball mark) as the performance standard for bats in their association sanctioned activities beginning January 1, 2018. Other organizations have announced or are planning to announce no changes to current and past bat rules.

In 1968, following the loss of his 12-year-old son to an asthma attack, Lou Lindebaum started Mike's Memorial Bronco League. Each year, the Mike's Memorial Award is given to a player within the league who best exemplifies good sportsmanship and fair play. The tradition of the Award lives on, and today, through the dedication and commitment of volunteers, the league has evolved into the Lake County Baseball League.
