No. 1 seed Holger Rune of Denmark got past Argentina's Tomas Martin Etcheverry 6-1, 3-6, 7-6 (6) Friday to reach the semifinals of the Swiss Indoors Basel.

Rune failed to convert two match points during the third-set tiebreaker to let Etcheverry back into the match. But on the 13th point, Rune hit a dead netcord for a flukey, if fortunate, point. Etcheverry double-faulted on the next point to allow Rune to advance.

Rune's semifinal opponent will be Canadian sixth seed Felix Auger-Aliassime, who outlasted Russian qualifier Alexander Shevchenko 7-6 (2), 3-6, 7-6 (1).

No. 4 seed Hubert Hurkacz of Poland will battle Ugo Humbert of France in the other semifinal. Hurkacz rallied past Dutch opponent Tallon Griekspoor 6-7 (6), 6-4, 6-4, while Humbert beat Swiss wild card Dominic Stricker 6-4, 2-6, 6-2.
