Skyview junior Andrew Kabacy defended his 4A Greater St. Helens League singles tennis title with a 6-4, 6-2 win over Battle Ground junior Gunnar Harlan on Saturday at Club Green Meadows. Kabacy and Harlan both advance to the bi-district tournament next week at Kent. The top eight from there will advance to state in May. Kabacy was a state qualifier last year, but was tested all season.
