KINGSPORT — Perhaps you can take the Hilltoppers out of the pool, but you can’t take the pool out of the Hilltoppers. Science Hill’s iron-clad grip on the Northeast Tennessee Swimming and Diving Championships went unbroken Saturday night when the ’Toppers held off a hearty challenge from Dobyns-Bennett to sweep all three titles at the Kingsport Aquatic Center. Science Hill won its 14th straight overall and girls championships as well as the boys’ crown for 13th time in the past 14 meets. “We swam Dobyns-Bennett earlier in the year and the girls got beat, and the guys was a very close meet,” said Science Hill coach Chris Coraggio.
