Sam Stosur steamed past American Christina McHale 6-1 6-3 in her first match at Edgbaston for six years, despite usually struggling on grass.
The Aussie ace looked in emphatic form at the Aegon Classic in Birmingham, racing away with the opening set after storming into a 5-0 lead in 14 minutes.
Stosur, who has flattened her trademark top spin serve especially to improve her grass court results, dominated the contest to make three wins on the bounce against McHale.
The #2 seed said: “It’s still work in progress, but a big part of it is believing and trusting that what I can do on grass court is going to work.
“I was really happy with the way I played and the way I felt. I’m pretty happy for my first match on grass this season, which helps my confidence.
“Points are obviously shorter on grass, but by the time we all get to Wimbledon we feel better with our movement.”
