To reliant on the big serve. He lost 6-0 in the third set to Nishikori which tells me he has a ways to go. Might become an Isner once people figure it out. Needs to work on other parts of the game.
I hope he gets better. He reminds me of Boris back in the day. But its a different time now. People return and move much better.
