Novak Djokovic is the world's No. 1. He has seven Grand Slam titles, including this year's Wimbledon. He has more than $65 million in career earnings and is poised to cash in big again at this year's U.S. Open.
But it's also a complicated time in Djokovic's career. Djokovic married Jelena Ristic in July after proposing last September. Ristic was pregnant at the time of his their wedding -- and she still is. But Ristic, who started dating him in 2005, is expecting to deliver any day now.
The baby's schedule might not mesh with Djokovic's. There is still more than a week left in the tournament, and Djokovic has made four straight finals in Flushing Meadows, winning in 2011.
Djokovic mentioned earlier in the week that his life is going through some changes with a wife and baby on the way. After his second-round victory over Paul-Henri Mathieu of France, Djokovic had the following half-serious, half-comedic, exchange with a reporter:
Q. You were talking the other day about a shift in priorities when you have a family. Now you're in a Grand Slam campaign. Talk about the experience of trying to maybe return that focus for at least a fortnight to the job at hand.
DJOKOVIC: Well, my focus is there. I don't understand how the people really got what I said, but I don't think there is anything wrong. Actually, I think it would be much wrong if my tennis is in front of my baby and my wife. I think there is no question about it. You know, my full priorities and commitments and energy goes to my family as much as I need to, but that doesn't mean that I'm not gonna play tournaments or not going to continue on doing what I was doing so far. Of course I'm doing everything that I can, respecting the same daily routines that I had for many years with my team. And it's working well. Of course this is what I want to do well. I have big support from my wife, from my family, from my team. We are all on the same page. There is nothing significant that is going to change. But of course baby comes, and now when I'm married - if you were married, you would understand.
Q. I am.
Q. Kids and all.
DJOKOVIC: I'm sure you get this -- you get a lot of questions (smiling).
After talking about his tennis for a bit, the subject of his future child returned again. Djokovic was asked about his plans to play for the Serbian Davis Cup team. Although Djokovic says he is currently expecting to play, he did mention his long-distance communication with Ristic.
"My wife is not here. I haven't seen her for a while. I just see stomach is growing on Skype and Facetime, but I want to spend some time with her," Djokovic said.
The image of Djokovic Facetiming his pregnant wife in the players' lounge is a humanizing thought. Djokovic may be the best tennis player on the planet, but he is also a husband awaiting a future child. It will be intriguing to see how such a circumstance affects his play in Flushing Meadows the next few rounds.
