<p>Venus Williams, playing her first tournament since returning from an autoimmune disease, continued her inspiring comeback at the Sony Ericsson Open on Sunday. <br /><br /></p>.<p>The former world number one followed up her shock win over Wimbledon champion Petra Kvitova with a nailbiting victory over Canadian wildcard Aleksandra Wozniak. <br /><br />Williams lost the opening set then saved a match point in the third before eventually prevailing 4-6, 6-4, 7-6 despite making 70 unforced errors. <br /><br />“I tried not to let anything discourage me today,” said Williams, who needed a wild card invitation just to get into the tournament. “I kept thinking about how I really need this match and I need these points. I keep thinking about the Olympics and I need my points.” <br /><br />Williams, who was diagnosed last year with Sjogren's syndrome, advanced to a fourth round meeting against former French Open champion Ana Ivanovic, who beat Daniela Hantuchova 6-2, 7-6. <br /><br />“You have to be ready emotionally,” Williams said. “I think about how miserable I’m gonna feel when I have a loss and I still spend that same time having a win, so I just keep try to digging deeper.”<br /><br />Victoria Azarenka, the current women’s world number one, continued to build her winning streak while Rafael Nadal and Andy Murray both sailed into the fourth round. <br /><br />Azarenka was untroubled beating British wildcard Heather Watson 6-0, 6-2. The Australian Open champion is unbeaten in 25 matches this year and on course for her fifth title of the season. <br /><br />Nadal is still chasing his first title this year but made light work of his third round clash with Radek Stepanek, winning 6-2, 6-2. <br /><br />Murray, the fourth seed in the men’s tournament, was given a free ride into the fourth round when his Canadian opponent Milos Raonic withdrew due to an ankle strain he picked up in the second round against French qualifier Arnaud Clement. <br /><br />Murray will next play Gilles Simon of France.</p>
