Subalinika was the pre -match favorite, who won 33 of its last 34 matches in the Australian hard courts.
But Keys, a powerful Baselner, is one of the few players from the WTA Tour who has weapons to harm Sabalka.
The explosive match -up resulted in a tremendous final where Keys won only another point.
An amazing opening set, where he released 11 winners and first served the rock, compiled the platform.
Cause was also helped with the onset of panic from Sablnka, which once unstable other service brings it into trouble.
In the opening game, two double errors allowed the caus to break, while one another set a second interval point in the fifth game, which Sabalinika handed over with a cut forehead in the net.
The Keys continued to play the lights, sharpened the clean winners from the back of the court and even better.
One of the surprising Subalinaka could only smile when the keys were emitting an ice cold drop shot on the way to 5-1.
However, after handing over another seat point after the fourth double error, Subalinika was angry with himself, which Keys took with the back -hand winner.
“He played a very aggressive game,” Sabalinika said. It seemed that everything was on his way. “
“I was just trying to put the ball back. I could not really play my aggressive tennis and couldn’t feel it well.”
