The Hopkinton High School girls tennis team knocked off top-seeded and undefeated King Philip on Thursday, posting a 3-2 road victory in the Division 1 South sectional semifinals.

The second doubles team of Victoria Allen and Romy Zinman posted a straight-set victory to get things started, and when No. 3 singles player Riley Krattenmaker picked up a 6-0, 6-0 victory to improve her season record to 17-0, the Hillers were one point away from victory. Following a rare loss for the first doubles team of Sophie Kaplan and Vani Sharma, second singles player Maddy LaMachia delivered a 7-5, 6-3 win to clinch the match. With the outcome already decided, Maya Storm dropped a three-set match at first singles.

“Each match I tell my team we need three points, no matter where we get them,” said fifth-year coach Lyn Calkins. “[Against King Philip], for instance, we got our points at No. 2 and 3 singles and second doubles. Everybody’s point is as valuable as anyone else’s. And anyone could have a much tougher match than the others.”
