it took 2 hours and 44 minutes to get rid of aging Karlovic.
he seemed excited after the match. good to see him get a little excited again.
nobody has any answers for djokovic. Rafa is the only one who can challenge him but he has a lot of hard work ahead of him.
it is going to be a long road back. the key is going to be getting back to his old dominating self on the red clay Europe in 2016.
and that is assuming he really wants to challenge Djokovic and get back in a position to chase history again.
he simply has to be able to dominate them on the red clay in order to challenge them on other surfaces.
Quick Fact: Did you know that Karlovic is now the ace leader in the history of the ATP Tour? He passed Ivanesevic a week ago. Karlovic is a nightmare to play especially when his serve is on. He hit some good volleys, but Rafa handcuffed him a lot last night. Rafa also had a great night passing.
Not to mention that was a tough first round match. His second match is tough too. He also has Wawrinka if it goes according to projections, so this is a pretty rough draw.
