In a huge upset on Sunday, second-seeded Agnieszka Radwanska of Poland made a shocking first round exit from the women's singles at London Olympics. Playing under Centre Court roof, Radwanska made a fine start to the match, but could not maintain the momentum and lost with a 7-5 6-7 6-4 to World No. 24 Julia Goerges of Germany.

After the match, Goerges asserted, "I played pretty aggressive and served well. I know if I play well it's dangerous for anyone and it was today, a lucky day.” Interestingly, Goerges had lost to Pole twice this year before this match.

On the other hand, Russian Maria Sharapova made a strong start to her Olympics campaign as she dispatched Shahar Peer of Israel 6-2, 6-0 and stormed into the second-round. Amidst a roaring crowd, Sharapova earned this victory. When asked about the noise, Sharapova quoted, "You hear a little bit of it, but it's not a big distraction.  When you see the schedule and you see your name on Centre Court, you know that your match is going to get done. Knowing what the weather forecast was going to be like today, I was pretty happy."

Due to sporadic rain, two hugely anticipated matches of Victoria Azarenka and Andy Roddick were postponed for Monday. In fact, doubles matches of Williams sisters and Federer-Wawrinka are also pushed to Monday.
