Serena Williams powered into the fourth round of the Australian Open with a 6-2 6-1 demolition of Ukrainian teenager Dayana Yastremska to continue her charge through the Melbourne Park draw.
The 37-year-old Williams, chasing a record-extending eighth Melbourne title in the professional era, barely broke sweat on a sunny afternoon at Rod Laver Arena as she sent 20 winners flying past the 57th-ranked 18-year-old.
Yastremska rolled her right ankle midway through and took a medical time-out to have her foot bandaged when trailing 4-1 in the second set.

It stalled defeat only briefly, however, as Williams broke her a third time in the set and claimed the match when the Ukrainian sprayed a cross-court forehand wide.
Williams will play the winner of the match between her older sister Venus and top seed Simona Halep for a place in the quarter-finals.

"I thought [Yastremska] did really amazing," Williams said.
Serena: Yastremska wasn't intimidated, she came out swinging
"She came out swinging and to be so young, she came out ready to go. When I was young I played against so many people and everyone I faced was intimidating and not easy. You just go out and swing and do the best you can."
