HARTFORD, Conn. (AP) When the Hartford Yard Goats make their long-awaited debut at the new Dunkin' Donuts Park, the Double-A team's starting nine won't be the first to have taken the field.

Police say four men were arrested and charged with criminal trespassing after they were caught playing baseball in the yet-to-be-completed ballpark around 8:30 p.m. Saturday.

An officer assigned to a security detail at the stadium discovered the men after hearing yelling and cheering coming from the field. When the officer went to investigate the commotion, he found a man on the pitcher's mound, another in the batter's box and two in the outfield.

Police say one of the men charged works for Centerplan Construction, a company involved in building the ballpark. The others were his friends.

Centerplan officials declined to comment.
