Indian Wells champion Jack Draper was toppled by a blizzard of blistering winners from Jakub Mensik amid a bizarre mass fan exodus disruption midway through the match at the Miami Open.

Talented Czech Mensik landed 21 aces in a straight sets win over Draper 7-6 (7-2) 7-6 (7-3).

British No 1 and new world No 7 Draper, headed into the clash exuding confidence having won the biggest title of his career in California, but Mensik quickly brushed it aside with a stunning performance with two clinical tie-breaks.

Draper was aiming to complete the coveted ‘Sunshine Double’ but he was unable to convert the sole break point chance he created in the second set.

Mensik’s victory sees him advance to the third round, where he will face Reilly Opelka who rallied to beat Danish 11th seed Holger Rune 4-6 6-3 7-6 (7-5).

The match was bizarrely forced to be temporarily suspended as Brazilian spectators, having waited on Grandstand for up to three hours, vented their anger on mass after hearing the news with Draper leading 4-3 that Joao Fonseca’s clash with Ugo Humbert was being shifted to the main stadium.

The 23-year-old Londoner asked for his match to be paused because of the distraction, with the umpire waiting several minutes for the Brazilian fans to leave.

“You absolutely can’t believe it,” Laura Robson said courtside. “The boos are very much justified because it’s just been announced that Fonseca and Humbert is moving to stadium court. All these Brazilian fans have been sat here for hours and hours are now just finding out and they’re trying to head over. The queues are going to be outrageous trying to get in.

“You feel so bad for them and it just makes it really difficult for the two players on court. There’s so much drama happening around the crowd and they’re just trying to play tennis. Just absolute scenes out here!”

Commentator Jonathan Overend added: “All these Brazilians are going to want to get out unless Jakub Mensik is their second favourite player. There are scores and scores of spectators in the temporary stands trying to get to the exits.”
