Li Na exits at hands of 43rd-ranked Czech, Barbora Zahlavova Strycova
Meanwhile, Novak Djokovic overcomes shoulder pain from fall to advance past Gilles Simon

Australian Open champion and second seed Li Na was eliminated 7-6 (5), 7-6 (5) on Friday by Barbora Zahlavova Strycova in the first major upset at this year’s Wimbledon.
China’s No 1 looked out of sorts for most of the third-round match on Court 1 and blew a set point in the second set.
In men’s play, top-seeded Novak Djokovic overcame a hard fall in the third set to advance to the fourth round with a 6-4, 6-2, 6-4 Centre Court win over Gilles Simon.
Leading 3-2 in the third set and with Simon serving, Djokovic lunged for a forehand shot and fell hard to the grass, rolling over and grabbing his upper left arm and grimacing in pain.
Luckily there is nothing damaged. I could play. Just the muscle was quite sore because of the impact
But after taking a medical timeout and receiving treatment by a trainer, he recovered to play out the final four games of the match, breaking Simon’s serve in the final game, his seventh break in the match.
