Holger Rune to face off against Hubert Hurkacz in the second round

Holger Rune will be in action on Wednesday for the Paris Masters

World No. 18 Holger Rune will meet Hubert Hurkacz in the next round of the Paris Masters on Wednesday, having defeated Stan Wawrinka in his opener. Opponent Hurkacz won his Round-of-64 fixture in straight sets against French player Adrian Mannarino on Tuesday.

Rune is currently on the rise having found his way to the final round of back-to-back tournaments in the month of October. With the title at the Stockholm Open and appearances in the final of the Swiss Indoors as well as the Sofia Open, the young Danish player has propelled himself to a career-best ranking of 18 this week.

Hubert Hurkacz was last in action at the Vienna Open, where he was handed an exit in the quarter-final round after losing to Borna Coric in three sets. The final set went to a tie-break and it was Croatian Coric who had the edge over Hurkacz at the end.

Rune will face Hurkacz for the first time in his career, meaning that their current head-to-head is tied at 0-0. The Dane will be hoping to thrive on his current form and pull off a surprise against the World No. 10.
