CHARLESTON, S.C. (AP) Serena Williams capped a dominant week with another powerful performance to beat Lucie Safarova 6-0, 6-1 and capture her first clay-court tournament in four years at the Family Circle Cup on Sunday.

Williams didn't drop a set in five matches this week and lost only three games over the weekend, dispatching Samantha Stosur, 6-1, 6-1 in the semifinals before ousting Safarova. She hadn't won a tournament on clay - or even gotten to a final on the surface - since taking the 2008 championship here.

Williams has said throughout the week how comfortable she felt in her short time on clay this year. That showed against the 25-year-old Safarova, ranked 26th in the world.

Williams served a 107-mph ace on match point, shrieking in joy and waving to the crowd.
