Like many kids, Tommy Hosmer of Bangor likes to spend his time on the ball field. But at 11 years old Tommy also spends his time doing something that isn’t so ordinary for someone his age. He’s made fighting cancer his hobby.”It’s affected him, both his grandparents passed away from cancer, so it’s something he’s very passionate about,” said Bobbi Hosmer, Tommy’s mother.Tommy organized a softball tournment on Saturday to raise money for cancer research in memory of his grandmother, who he called “Mimi.”"I wanted to do this because my grandmother passed away from ovarian cancer and she never really got to come to a lot of my games only because she was so sick,” said Tommy.Team Mimi’s Softball Tournament is the latest in a series of events Tommy’s organized. He’s previously held a book sale that raised over $3,000 for cancer research and a bake sale and bottle drive that raised $1,200. He hopes the softball tournament will raise more than both of those events combined.”He knows what he wants to do,” said Tommy’s father Paul Hosmer, “He lets us know and we kind of help him. It’s his idea we just help him,”The turnout at these events is proof that lots of people want to help. “For a child to admire his grandmother like that and have such a good cause to help fight cancer, it was something that we all just jumped right in,” said Aaron MacDonald, a participant in the softball tournament.”It’s not hard to get people behind a cause like this because if you ask everybody out here, I think they’d say they know somebody that’s been affected by cancer,” said Paul.It’s all of those people and all of those families that Tommy had in mind when he put this event together as well as the others he’s organized before.He said, “I just wanted to help other people that have cancer like my Mimi had.”"I don’t think he realizes the extent of what he does at 11 years old, but he has named this an annual tournament so he’ll definitely going to continue it,” said Bobbi.All of the proceeds raised at the softball tournament will go toward the Champion the Cure Challenge on August 18, which raises money for EMMC’s CancerCare of Maine. That event, which Tommy will be participating in, just happens to be scheduled on his 12th birthday.
