Carlos Alcaraz and Jack Draper were involved in an unfortunate video review technology controversy in the Indian Wells semifinal. The video call unexpectedly changed the outcome of a key point and influenced the Indian Wells Masters 1000 semifinal.

Jack Draper upset Carlos Alcaraz on his favorite court in the world Saturday at the BNP Paribas Open at Indian Wells, sprinting to a lead and weathering an Alcaraz blitz, then holding it together and letting Alcaraz play just loose enough to give him the opening to break the Spanish champion who had not lost here in nearly three years.

Jack Draper toppled two-time defending champion Carlos Alcaraz 6-1, 0-6, 6-4 on Saturday to reach the BNP Paribas Open final.
