Roger Federer is now enjoying holidays.
Following a brief exchange, Donaldson laughed and said, "Ah, I'm sorry".
Speaking about the consequences of the controversial addition to the game, Nadal said ahead of his Monte Carlo title defence: "For me it's not the ideal thing but if the sport is moving that way or they want to move that way, the only thing I can do is accept it and play".
He opens with a bye and then either Pablo Cuevas or Fernando Verdasco - both are inconsistent these days - before a potential round three with Milos Raonic, another player whose level is tough to judge on clay now.

Nadal will be chiefly concerned with arriving in Paris in tip-top shape but also in the back of his mind is the fact that his number one ranking is hanging by a thread. As you may expect from this, big-servers are not suited at all in what are very different conditions to what was witnessed last week on the quicker clay in Houston, and in Monte Carlo in this time period, a mere 0.30 aces per game were served, down from the 0.38 ATP clay average.
A furious Jared Donaldson confronted umpire Arnaud Gabas in a heated exchange during his first-round defeat to Albert Ramos-Vinolas at the Monte Carlo Masters on Monday. I always try to be very focused at the beginning of the tournament on what I'm doing.
After significant rest during the second half of a year ago and a medical procedure in February, Djokovic spoke confidently of being pain-free - at long last.
