1-1 set and game 15-15, the ball was judged to have popped out twice before the draper reached a drop shot by the referee Mohamed Raan Nien.
It was a wrong call from a civil servant, but the player can now use video technology in Wells to question the decision of double bounce.
After the draper requested to play immediately, his challenge was successful, allowing Lahyani to overturn the original decision.
He received a point of 15-30 lids and regained his propulsion with his favor and eventually proved the difference.
Thank you Draper said, “It’s really good for tennis,” but Alcaraz insisted that it was “not affected.”
But his level was over for the third year of the bid to win Indian Wells.
Left -handed Draper faces Denmark’s Holger Run in the Sunday Finals at the Masters 1,000 event in California on Sunday.
Rune, 13th place, has reached his fourth master final with Russia’s fifth seed Daniil Medvedev, 7-5 6-4.
