Jack Draper ousted defending champion Carlos Alcaraz from Indian Wells in a bizarre semi-final that featured a pivotal double-bounce controversy early in the deciding set.

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.
