World No 1 Serena Williams dispatched Victoria Azarenka 6-1, 6-3 in the women's final to claim her fourth straight title.
The American crushed her third-ranked opponent in one hour and 33 minutes to continue her ominous form ahead of the French Open.
It was Williams’ 24th consecutive win on the WTA Tour and saw her add to the titles she has won in recent weeks in Miami, Charleston and Madrid.
