It's been a long year for both Korda and Auger-Aliassime and while neither played too many matches, they both want to go on a vacation. To do that, they had to withdraw from the Sofia Open, which will take place next week.
These ATP events in the final week of the season generally are filled with withdrawals as many players elected to rest up instead of play because there is very little to play for.
The draws generally feature a lot of players who are fighting for the ATP Finals in case they need more points; however, most of them drop out once it becomes clear that they're in or can't get in.
That's the case for both Korda and Auger-Aliassime, who technically had a chance to book a spot in the ATP Finals when they entered the Paris Masters draw, but since then, they're out of the race for the ATP Finals.
Because of that, there is very little reason to really play in Sofia next week. Both should take some time off and rest up before returning next year.
They're not the only players who withdrew from the event because Taylor Fritz will also likely withdraw from the event and a couple of other players.
Still, the draw looks pretty decent even with all of those withdrawals; players like Lorenzo Musetti, Adrian Mannarino, Alejandro Davidovich Fokina, and others are likely to stay in the draw.
When it comes to Korda, he finishes the year with 26 wins and 17 losses. He played two finals but failed to win a trophy.
Auger-Aliassime finishes the year with 24 wins and 20 losses. His only final came recently in Basel, and he won that one, essentially saving his season.
