Texas Rangers pitcher Cole Hamels and his wife, Heidi, are donating a mansion and 100 acres of land in southwest Missouri to charity that provides camps for children with special needs and chronic illnesses and their siblings.

The 32,000-square foot home -- which Realtor.com estimates to be worth over $9.4 million -- will be donated to Camp Barnabas.

The mansion and land is near Table Rock Lake near Reeds Springs. Heidi Hamels grew up in Buffalo, Missouri.

The Springfield News-Leader reports an attorney for the couple said they thought the mansion would be their dream home. But when Hamels was traded to the Rangers, they moved to Texas and never moved into the Missouri house.

Hamels said in a news release Friday that he and his wife wanted to help the charity make children's dreams come true.

"Seeing the faces, hearing the laughter, reading the stories of the kids they serve; there is truly nothing like it," he said in the statement, according to ESPN. "Barnabas makes dreams come true, and we felt called to help them in a big way."
