Serena Williams crushed world number one Victoria Azarenka of Belarus 6-1, 6-3 on Sunday to win the Madrid Masters and make a return to the number six ranking.
The American has now won back-to-back WTA clay titles after claiming Charleston in the US a month ago. She now owns five trophies on clay.
The bruising victory lifted the American to a 7-1 record over Azaranka, who won her only match in the series in Miami, 2009.
Williams swept to a double-break in 12 minutes at the start, secured the set in 26 minutes on a double-fault and continued the demolition in the second set to complete the win in 64 minutes.
Williams has now won 13 consecutive clay matches including the Fed Cup in April.
