Singing "Take Me Out To The Credit Union" in Sharon during Friday's Boston Red Sox home opener would be appropriate.

Employees at the Sharon Credit Union's Pond Street headquarters and five branches (Sharon, Mansfield, East Walpole, Foxborough and North Attleboro) will wear Sox gear Friday as a rally against cancer.

For the fifth straight year, the financial institution is a player in the "Rally Against Cancer" supporting the Jimmy Fund and the Dana-Farber Cancer Institute, Sharon Credit Union corporate trainer Robin Burns said Monday.

The event invites people to donate $5 or more for the right to wear their Sox jerseys and caps to work or school that day, according to an event press release. The top fundraising business and school are eligible to receive a visit from Red Sox pitcher Daniel Bard.

The Sharon Credit Union's involvement grew out of a blood drive the financial institution has held annually since Burns' nephew, Jonathan, died of cancer in 2007, she said.

"I think everyone is touched by cancer," Burns said.

"(And the rally) is a good excuse for us as a financial institution to involve the community."

The credit union has raised more than $2,000 over its four years in the rally, Burns said. Organizers have exceeded this year's goal of $400, she said.

"Some people go online and make larger donations (than $5), Burns said.

"If people don't wear Red Sox (gear), they still donate."

And the credit union's offices will have a Fenway Park flavor on Friday.

"Robin gets some steamed hot dogs going early," Senior Retail Officer Maureen Gregory said.

"Then, we have someone from each of our branches come over and pick up their hot dogs, chips and cookies."
