What I noticed: Day 4

• Serena won in straight sets. She played well but seemed annoyed with herself or the sun, or the universe. Who knows. She told Stubbs in the post match interview that she wouldn't make a good ballerina with wobbly ankles. 
• Andy Murray is hitting his forehand harder than I remember. But I miss the muttering and monologuing. The winning however I do like. 
• Domi Cibulkova dress is always so short. It's like she is trying to make herself seem taller by showing more leg. 
• David Ferrer won in 5-sets after losing the first. If that surprises you. It shouldn't. 
• Ana Ivanovic won in straight sets. Her serve and forehand were looking good. 
• Maria Sharapova played crisply and has lost two games in her journey to the third round. She also talked doubles at the Olympics and the apocalypse in her presser. 
• Petra Kvitova was crusing against Carla Suarez Navarro then she wasn't dropping the second set and going down an early break in the third before rebounding to advance. 
• Nicholas Mahut advance to the third round which is totally awesome. 
• Sabine Lisicki had a much easier advancement to the third round then she did to the second. Defeating Peer in straight sets. 
• Andy Roddick won the first set. He injured his leg early in the second set took a time out to get it looked at or taped up. He lost the second and third sets even trying to bravely come back at the end of the third set in which he lost when a double net cord drippled over to give Lleyton the set. Then Andy retired. Get better soon Andy!
