MLB announced this year's 30 honorary bat girls for its annual "Going To Bat Against Breast Cancer" initiative on Tuesday.

Each of the 30 Major League teams will be represented by a bat girl on Mother's Day, this Sunday, as part of MLB's effort to raise awareness and money for breast cancer research.

The honorees were chosen by the clubs for demonstrating an extraordinary commitment to the battle against breast cancer. All 30 bat girls will be honored in a pregame ceremony by their respective team, either on Mother's Day or at a future home game for those teams playing on the road on Sunday.

Every 2019 honorary bat girl's story can be found on HonoraryBatGirl.com.

MLB and CrowdRise will also partner to host a fundraising contest for the 30 honorary bat girls to raise money for Stand Up To Cancer and Susan G. Komen, with the winner getting a trip to the 2019 World Series.

The honorary bat girl program, which began in 2009, is part of Major League Baseball's yearly slate of initiatives to raise awareness of breast cancer on Mother's Day.

On Sunday, players around the Major Leagues will once again use pink bats and wear pink wristbands, which they've been doing since 2006 as part of Going To Bat Against Breast Cancer. They'll also wear specially designed pink and team-color hats, and uniforms will display the symbolic pink breast cancer ribbon and the MLB breast cancer awareness logo.
