On a very windy day for tennis, Grinnell took full advantage and defeated Knoxville 9-2 on Monday. The Panthers were swept in the singles matches and that would clinch the match for the Tigers. Knoxville’s only wins came at number one doubles with the duo of Alex Griggs and Anna Sanderson and at number five with Naudia Vinsick and Reagan Little. The Panthers host Albia at the Joel Tonda Tennis Center on Thursday.
