MELBOURNE - Peng Shuai equaled her best result in Australian Open Friday after she breezed into the last 16, beating Kazakhstan's Yaroslava Shvedova 7-6, 6-3.

Peng lost her opening service game before she broke back in the second.

The 29-year-old Chinese saved five set points in the 10th game and leveled at 5-5 on the second break point.

In the tie-breaker, Peng came from 1-4 down to win the set on her second set point.

Peng dominated the second set when she broke Shvedova's serve in the seventh game. She managed to grab the third match point in the ninth game and won the second set in 58 minutes.
