• Video: Rafael Nadal and Novak Djokovic were in South America for an exhibition event with David Nalbandian and Nicolas Massu. A great moment occured during the press conference when Nadal tries to translate Djokovic's English comments to Spanish and proceeds to translate them into... English (1:14 mark).
• John Inverdale may not be back for Wimbledon next year after controversially describing Wimbledon champion Marion Bartoli as "not a looker."
• Speaking of Bartoli, she talks to CNN about the role of art in her tennis, her memories of her Wimbledon triumph, and her decision to retire. Interesting to hear her describe her game as "artistic, in a way."
• Serena Williams tells CNN that 2013 was a make it or break it year for her career.
• Not good to hear: John Isner is still dealing with his knee injury.
“I had an MRI done and had people look at it. I’m not going to need surgery, but there is an issue under my kneecap. It’s about getting everything surrounding the knee stronger. It doesn’t bother me at all when I’m just walking around. But sometimes it hurts when I’m doing something strenuous.
“So I haven’t touched a racket for a while, but I am lifting some weights and doing some cardio on the bike. It’s active rest, because when I take time off completely my body feels worse. And I can’t baby this [knee] forever. I need to push myself.”
• Carl Bialik at The Wall Street Journal makes the case for Novak Djokovic's inclusion in the discussion of greatness.
He has spent 101 weeks at No. 1 in his career and has a chance to regain that spot next spring, which would be a remarkable achievement considering how rarely No. 1 Rafael Nadal has lost in the past 12 months. Three of Nadal's seven losses were against Djokovic.
Djokovic also has won 61% of his career matches against the Top 10 -- a higher winning percentage than five of his seven predecessors, including [Andre] Agassi and [Jimmy] Connors. And none has a longer winning streak against the Top 10 than his best of 15, according to data provided by Jeff Sackmann of Tennis Abstract. Djokovic has won three year-end finals (among the seven, only [Ivan] Lendl has more). He has a Davis Cup -- Connors doesn't -- and an Olympic medal, which only three of the seven do. He has 41 career titles. The other seven averaged 66.
And he won't turn 27 for six months.
