Serena had a tough battle with former World #1 Ana Ivanovic on Friday night, coming back herself from 2-6 down in the first set to win the last two sets 6-3 7-5. This was an important victory for Serena, facing a player with the most wins on tour this year, who had beaten her at the 2014 Australian Open. Ivanovic played very well, at times out-hitting Serena and showing none of the mental lapses that have plagued her game in the past; she will be rewarded by entering the Top 10 on Monday.
Earlier in the week Venus Williams surprised many by putting on a vintage display of power and will to defeat Victoria Azarenka 6-4 7-6(1). Petkovic managed to defeat her in one of the best matches of the year, 6-1 3-6 7-5. Venus fought hard, coming back from a break down in both the second and third sets, eventually evening the match out at 5-all in the final set but lost the two last games and the match.
