- Has Rosol destroyed our supreme jadedness over upsets? I think we’re pretty wise as a tennis community, but it is safe to say that we often underestimate players we know little about. When you have superhuman energy levels, you can pull off the unthinkable. Dodig did the same thing last year in Montreal.

- As I briefly alluded to in my tactics post, Andy Murray can have a heck of a time sorting it out against lesser opponents, and those that give him little pace on the ball. While he can serve big, he desperately needs to improve the punch of his shots, and particularly go for the backhand if he ever wants to win this tournament. Hit the ball, Andy.

- I haven’t seen much of his play, but Juan Martin del Potro may just be sorting it out on grass. The surface will never be kind to him in the bounce category, but he has the power in his forehand to back up the serve. He also has underrated defense, especially with his block backhand that will allow him to be in more return games than an Isner, Querrey or Raonic. A match against a barely mentioned Ferrer is a tough test on Tuesday, but there is a legitimate chance that he could improve his already impressive run.

- How soon we forget. Azarenka spent a total of 3 hours and 22 minutes in her first three matches and has now blown out Ivanovic, dropping only one game. While focus has largely been around the new number 1 Sharapova, Serena and defending champ Kvitova, it was only weeks ago that Azarenka was number one and coming off of her first major title. Like any massive hitter her game translates well, and her willingness to go for big shots is paying off in spades.

- Last year at Wimbledon, Kerber lost in the first round to one Laura Robson. (Thanks @BenRothenberg.) Since then she made the semis of the US Open, drastically improved her fitness, found success on clay, and has now destroyed Kim Clijsters to make the quarterfinals of Wimbledon. Her massive lefty game can at times remind of Kvitova, and I went as far as saying that she would take advantage of the draw and make the final. At this stage, that is not an impossible ask.

- I must say, I underestimated Kvitova. She hasn’t done a whole lot since her Wimbledon win last year, but she is proving that grass court specialists can exist. With Serena struggling to dominate, that match is nearly impossible to call. Still, I’d take Azarenka as the favourite to make the final.
