Roger Federer and Rafael Nadal open play Sunday at Indian Wells.

“In the end it didn’t go my way. That’s life, that’s tennis,” the 38-year-old Karlovic said. “That’s how it goes sometimes. I was not really moving well…Serve was good. Volleys were OK so I have to look at the positives and continue with my journey.”

“I feel amazing,” he said. “It’s a great feeling to get my first ATP win, and to do it in a 1,000 event, to play Djokovic, it’s a pretty surreal feeling. I’m going to enjoy this as much as I can right now.”
