McDonogh wins: Although McDonogh compiled enough team points to secure the Interscholastic Athletic Association of Maryland A Conference tennis championship before the finals, the Eagles underscored their undefeated season by winning four of five individual and doubles matches to outdistance runner-up Bryn Mawr, 19-13.
Severn and Mount de Sales tied for third in the team race with 11 points each behind Bryn Mawr and McDonogh, which ended a 12-year A Conference title drought in the process. The Eagles earned a B Conference banner in 2009. McDonogh's lone setback came in No. 1 singles, in which defending champion Cameron Corse of Bryn Mawr defeated McDonogh's Sarah Fioretti, 6-1, 6-1, to complete a second consecutive perfect season. Corse shutout Severn's Addie Hinton to reach the final.
After topping Mount de Sales sophomore Chloe Boustany, 6-3, 6-2, on the other side of the bracket, Fioretti said that she had "to stay on point" to pull off an upset of Corse. "She is very consistent, and she hits the ball hard," Fioretti added.
