Wimbledon 2012: 'Queen' Victoria Azarenka books semi-final against Serena Williams "Go on, Queen Victoria!" one wag shouted towards Azarenka, and the call was heeded as the Australian Open champion vanquished the young Austrian 6-3, 7-6 to book a semi-final date with Serena Williams on Wednesday. Twice the 21 year-old cancelled out the breaks of serve to set up a tie-break that the second seed, managing her emotions under pressure, won at 9.19pm to reach the last four for the second straight year. "There's no better opponent than Serena to face in the semi-finals," she admitted." I'm looking forward to the match, even if it's not going to be easy. It's the semi-final of a grand slam, what else do you expect? Since 2010 she has failed to progress beyond the first round at any grand slam besides Wimbledon, where she has featured in back-to-back quarter-finals - also losing the 2011 instalment to Azarenka. She has developed a highly deliberate serving motion and was taking, on average, three times as long for her service games as Azarenka. She toiled to keep pace with the Belorussian but suffered a collapse in concentration in the ninth game of the second set, sending two forehands wildly long. Azarenka was hesitant in seizing the opportunity, facing two break points, and netted on the second to hand the initiative straight back. She again faltered at 6-5 but her resilience in the ensuing breaker was decisive as she took the second of four match points.
