The Team Mimi Softball Tournament and Celebrity Dunk Tank will take place this Saturday in Bangor.

This annual softball tournament was started by 10-year-old Tommy Hosmer, who wanted to do something in honor of his grandmother after she died of ovarian cancer. He came up with the idea for a softball tournament for cancer charities and named it after his 'Mimi,' hoping that it would help other families avoid going through the heartbreak that his family had experienced.

Now 17-years-old, Tommy is still holding the event, and has added a Celebrity Dunk tank, so spectators to the games would be able to have some fun too. And spectators are encouraged to stop by, cheer on the teams, and make a donation to EMMC's Champion the Cure Challenge.

Last year, Tommy was honored by U.S.Cellular's 'Future of Good' program, which recognizes the charitable works of young people across the country. He's currently featured on the program's website, along with this quick documentary about the event.

The games will start at 8 this Saturday morning at the Union Street Athletic Complex. The Dunk Tank, that will feature a chance for folks to submerge some local celebrities in a tank of water, will run from 11 a.m. to 3:30 p.m. In addition, there will be concessions available and a number of raffles, all to benefit local cancer research. And what's a day in the sun without ice cream? The Darling's Ice Cream For A Cause Truck will arrive at 2:20.

Take yourself out to the ballgames this Saturday in Bangor!
