PORTLAND – They are lifelong Boston Red Sox fans with a passion for baseball, so perhaps it’s not all too surprising that Dawna Bonneau and Mark Hall plan to step up to the plate Saturday to say “I do.”

That’s home plate at Hadlock Field, home of the Portland Sea Dogs.

Hall, 43, and Bonneau, 33, both of Portland, reserved the 6,975-seat stadium for their exchange of wedding vows, to be carried over the public address system. About 170 guests will witness the ceremony from box seats behind home plate.

The Sea Dogs, who are charging $1,100 for use of Hadlock Field, said the wedding is the first ever held there.
