Ivo Karlovic vs. Feliciano Lopez
This should be a fun match. Both men have played well since Wimbledon ended. Ivo won a title on grass in Newport, Rhode Island and was runner-up on hard courts in Washington, DC. Lopez won a title on clay in Gstaad. Ivo leads their head-to-head series 5-3, but they have not played since 2014. There should be a lot of service holds in this match. Lopez is more well-rounded than Ivo, but Ivo has one of the top 5 serves on tour.
My Prediction: Feliciano Lopez d. Ivo Karlovic 7-6, 6-7, 6-3
