What material did Djokovic ask from umpire during Shanghai Masters match? It's an old tennis trick

Novak Djokovic was today battling not only Marin Cilic, but also enormous humidity and heat that is currently ruling in the Shanghai Masters venue. So he used an old tennis trick.
Several times, Novak was seen trying to wipe his hands for about ten seconds, and several times he did not place the shots as he wanted, so he asked the umpire for some - sawdust!
Yes, it is great for avoid grip-related problems, and Djokovic used it to rub his hands.

In addition, Djokovic put some in his pockets so that he would not have to go back to the bench all the time.
Ivan Lendl, a former Grand Slam champion, was also known for this move, and now we see this method again, which has been known to be used in the world of tennis.
Djokovic did the same in Miami, for the same reasons. The Serbian ace eventually beat Crotia's Cilic 2-0 and progressed to the next round.
