LHS beat Heights, 3-1; Topeka Seaman, 4-0; and Topeka West, 2-1.
Lawrence's Scott Elwell and Bryan Allen were undefeated in singles, while Mattijs van de Leifvoort and Jeff Craig were undefeated in doubles.
"Scott played well, but he was not challenged," LHS coach Dick Wedel said. "Truth be told, I was probalby happiest about Dustin Huff and Galo Salcedo's win. They had a hard time in the first two matches. But in the third match, they made some adjustments, tried to cut down on errors and they won. I was pleased for them."
