With her forehand in scintillating form, the fourth-seeded Australian delivered a ruthless display on the green claycourt surface at Daniel Island to win her fifth successive match against the Russian. World number 11 Stosur broke her opponent three times in dazzling sunshine to sweep through the opening set in 18 minutes.
Trailing 0-3 and 15-40 on serve in the second, seventh-seeded Zvonareva won her first game of the match after repeatedly smashing her racket to the ground in frustration.
Although Stosur was surprisingly broken in the seventh when her backhand sailed wide, she immediately broke back for 5-3 before serving out for the title.
The 26-year-old raised both arms above her head in celebration after sealing victory with a forehand winner.
