Continuing the run of shocks and surprises at the Indian Wells tournament after 3rd seed Victoria Azarenka and 5th seed Angelique Kerber lost in the 2nd round and 5th seed Maria Sharapova going out in the 3rd round, 20th seed Flavia Pennetta caused the greatest upset of all when she defeated top seeded Na Li in the first semi final on Friday afternoon for the best result of her career to date. Having already removed the 16th and 17th seeds, Sam Stosur and Sloane Stephens respectively, she came on court knowing that she had been comprehensively beaten by the Chinese at the Aussie Open this year. She had four breaks of serve in the first set but could not capitalise on them, so the set went to a breaker which she won 7-5 after an hour and six minutes. Li went up 2-0 in the second set, but the feisty Italian allowed Li just one more game as she closed out the set 6-3 in just 43 minutes.
In the night match, 2nd seed Aggie Radwanska took on Simona Halep, the 6th seed – who will be the new world number 5 in the WTA rankings on Monday. The Pole had lost both of their two last meetings but came out firing with all her remarkable ammunition and took a 4-0 lead and a point for 5-0, but Halep played some inspire tennis to get three games on the scoreboard before the Pole served out the first set with an ace. In the second set it was Halep who got the first break to build a 3-1 lead but Radwanska came back with four games on the run to lead 4-3.The Pole then held and so did the Romanian – after saving two match points with both players continuing to play glorious tennis, before Radwanska served out the set 6-4.
