Del Potro vs Berdych

Hard to predict a winner when Juan Martin Del Potro (9th ATP rank) will play against Tomas Berdych (7th). I expect this to be a close match and it shouldn't end in three sets. The head-to-head series also show that we can expect to see a close match. So far the score is tied at 3-3. These players last time have met less than a month ago. Then Tomas Berdych won at Madrid in straight sets but this was a very difficult match and has ended with the score 7-6 7-6. Juan Martin Del Potro had a pretty easy way to this round at Roland Garros and only dropped two sets so far. Berdych won in straight sets against Sela and Llodra but needed all five in his latest match against Kevin Anderson. As the class of these tennis players is similar hard to believe the match will be decided in straight sets so I expect more than 40 games to be played here.
