San Marcos swept nine singles sets en route to a 12-6 boys tennis win at Ventura on Monday in a Channel League match.
Kento Perera, Dominik Stefanov, and Daniel Newton provided all the margin the Royals would need.
The Royals are one win away from a Channel League championship. If they beat Buena on Tuesday, they’ll earn no worst than a share of the title. Co-leader Dos Pueblos plays Santa Barbara on Tuesday, and if the Chargers win they also would tie for the title.
