JOHNSON CITY — The preliminaries are over for the District 1 Large Schools tennis tournament. Now the real fun begins. The opening rounds took place Monday at Liberty Bell Tennis Complex, and a long day of action set up Tuesday’s semifinals and championship matches, which will be played at Dobyns-Bennett’s courts. By the end of the day, Science Hill boys coach Kelly Lane had a big smile on his face. “It couldn’t have gone any better for the boys,” Lane said.
