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.

Twelfth-seeded Holger Rune beat fifth-seeded Daniil Medvedev 7-6, 6-4 on Saturday to advance to the BNP Paribas Open final.

Draper ran through a Murder's Row of players to reach the semifinals against Alcaraz. He beat Brazilian rising star João Fonseca in his first match, before beating American Jenson Brooksby next. He then beat the top two of the three top Americans, third-seeded Taylor Fritz and 11th-seeded Ben Shelton.
