World No. 10 Casper Ruud will play the Stockholm Open, from November 6-13.
Norwegian Ruud, 22, will enter the event – the oldest indoor tournament in the world – in the second round.
Ruud made his Stockholm main draw debut in 2019, losing in the first round to Filip Krajinovic.
The Stockholm Open field looks strong with world No. 4 Alexander Zverev and Wimbledon semi-finalist Denis Shapovalov signed to play.
