Novak Djokovic faced Andrey Rublev for the first time in their careers, as the two look to go 2-0 and win their pool. And the first meeting with the legend was a little too much for the Russian.
Meanwhile, Stefanos Tsitsipas (a former champion at the event) was a late scratch for his match against Casper Ruud, because of an ongoing elbow injury.
Cameron Norrie was the second alternate to get a chance to play this week. But after a good start, Ruud found his bearings.
