Fifth seeded Serena Williams captured her 40th career WTA title by overpowering ninth seeded Czech Lucie Safarova 6-0, 6-1 at the Charleston claycourt tournament on Sunday.
The 13-time Grand Slam winner needed just 58 minutes to dispatch Safarova in her first final appearance since last year's US Open when she lost to Samantha Stosur.
This marked Williams' first WTA title since turning 30 in September and she is the first 30-year-old to win on the green clay in Charleston since Martina Navratilova in 1990.
Williams, who did not drop a set in Charleston, improved to a perfect 5-0 against world number 26 Safarova. She won her quarter-final match when German Sabine Lisicki retired after 40 minutes in the first set with a foot injury.
Williams hammered five aces, won 20 of 25 first serve points and saved four of four break point chances on Sunday.
She now needs one more title to tie Kim Clijsters (41) for 13th place on the WTA all-time list.
This marked the second Charleston title for Williams who also won here in 2008.
Safarova was a heavy underdog against Williams, despite her one-sided 6-0, 6-0 win over Polona Hercog in the semi-finals.
