Pound for pound Donaw David Escalante was born at Tucson Medical Center at 4:25 a.m. yesterday, in time to make his dad, Donald, the winner of a Father's Day roast presented by the Cowbelles. The 7 lb., 10 oz. roast matches Donald's weight and was presented because he was the first baby reported reported born in Tucson on Father's Day. His mother's name is Barbara. The Cowbelles are the unofficial women's branch of the Arizona Cattle Growers Assn. (Star photo) '
