Azarenka into US Open final
The second seed put an end to the fairytale run in New York for the unseeded Italian with a straight sets triumph after one hour and 34 minutes on Arthur Ashe Stadium.
However, the final scoreline did not do justice to how hard Pennetta – who knocked out three seeds to make the last four of a grand slam for the first time – made the 2012 runner-up work to reach Sunday’s showpiece.
Both players struggled to keep their serve with 13 breaks in the 18 games, though Azarenka’s extra power proved the difference at the crucial stages of the contest.
The tone was set when both players were broken immediately, though Pennetta did then hold to move ahead. That, though would be her only success on her own serve.
Azarenka had her troubles too, including sending down six double faults, and she needed no fewer than six set point opportunities before finally edging in front.
Azarenka will now play the winner of the semi-final between Serena Williams and Li Na. (Sky)
