Keys needed just an hour to see off Tomljanovic in a 6-4 6-2 victory and extending her first-round record at Wimbledon to 6-0.

Her power and pace of shots was the difference at the end generating 19 winners to just seven unforced errors. She also didn’t face a single break point during the match.

Keys won 86 percent of points behind her first serve and fired four aces past Tomljanovic.

However, when walking to the press Keys mentioned she was battling nerves during the match.

“It’s always tough to play someone that you know pretty well, but also you have your first round nerves too so it’s a weird combination,” Keys told the press.

“I’m just happy to be through.

“Not only happy with how I played and executed what I wanted to do but more how I handled my nerves," she said.

There are still three Aussie women to play their opening match with Sam Stosur, Ash Barty and Daria Gavrilova all on court from 8:30pm tonight.
