Venus Williams pummeled Ana Ivanovic 6-2, 6-1 in a second-round match between former world No. 1s at the Dubai Championships on Wednesday.

Williams showed the form that once delivered her seven Grand Slam titles.

Ivanovic couldn't take advantage of the two break-point opportunities Williams offered in the sixth game of the first set.

Williams, a wild card, lost only seven total points in her other six service games.

In the quarterfinals, Williams will play Italian qualifier Flavia Pennetta, who upset second-seeded Agnieszka Radwanska 6-4, 6-1.

Radwanska, the 2012 Dubai champion, also was ousted in the second round at the Qatar Open in Doha last week.

She led 4-1 then lost eight games in a row to be 6-4, 3-0 down.

The only other game Radwanska won was the fourth game of the second set.
