The Dallas Little League Baseball Complex (it’s the new field at Winfrey Point at White Rock Lake) officially opens Thursday, Sept. 9 at 6 p.m. Last February, we reported that the fields would be ready by April 2010 — don’t blame us. You know how these things go. On opening night — provided this rain stops long enough for the field to dry up — Parks and City officials including Councilman Sheffie Kadane and members of Dallas Little League will be on hand for the ceremonial first pitch and inaugural game.
