After the match and the Italian's victory, journalists wondered whether the Spaniard's withdrawal meant that he was now an even bigger favorite to win his second Grand Slam of the season.
"I don't know. I don't think that's a topic we should be discussing. The most important thing to say is, first of all, tennis needs Carlos, tennis is much better with him. And I too... I believe that he will come back stronger than before. Injuries are always difficult, especially the wrist - it's one of the particularly sensitive parts of our tennis players' bodies, he knew how to complicate life for many," said Janik.
It is unknown when Alcaraz will return to the field.
"The most important thing is to take your time, not to rush your return so that it doesn't get complicated and become an even bigger problem," concluded the world's number one.
Siner and Alcaraz have crossed racquets 17 times on the ATP Tour so far, with the Spaniard leading 10-7 in wins. The Italian won his only match this year in the final of the Monte Carlo Masters.
