Venus Williams will next play seventh-seeded Angelique Kerber of Germany after advancing to the third round of the Olympic tennis competition

Williams reached the third round Tuesday by beating Aleksandra Wozniak of Canada 6-1, 6-3.

Williams dominated her singles match with her aggressiveness, which is what makes her so dangerous on grass. She won 15 of 16 points when she reached the net, and of the points she has won through two rounds, nearly one-third have come when she moved forward.

''Every day I'm just concentrating on trying to bring my best tennis out,'' Williams said. ''And honestly, if there's a time to do it, it's now.''

Against Wozniak, Williams won eight consecutive games - which she didn't even realize.

''I know I'm in the zone when I don't know the scores,'' she said. ''In the second set, I had to look up and see what the score was. I didn't realize the first set was 6-1. I'm just playing. So that's always a good sign.''

Williams won her most recent tournament title 2-1/2 years ago, and she took a long layoff after being diagnosed in 2011 with an autoimmune disease that causes fatigue.
