Alexander Zverev ended a frustrated Roger Federer's hopes of a third Shanghai Masters title as he claimed a stunning 6-3, 6-7 (7-9), 6-3 quarterfinal triumph.
The German took his head-to-head record against the 20-time Grand Slam champion to 4-3 with a display of immense quality and huge character.
Deeply frustrated Roger Fedeerer was given a point penalty out of the Shanghai Masters quarterfinals in a bad-tempered defeat to Alexander Zverev on Friday. Swiss legend Federer was penalised after twice hitting the ball out the court in anger.
Federer, winner of the title in 2014 and 2017, frequently showed his displeasure and repeatedly argued with the umpire, even landing a point penalty after hitting the ball into the crowd in anger.
But his unrest was largely down to the brilliance of Zverev, who defiantly overcame the setback of missing out on five match-point openings in the second set.
It was Zverev who forged ahead, seizing on a break-point opening that came after a stinging forehand return winner. He then confidently held serve for a 5-2 lead as Zverev continued to look the more settled of the two, a fact further underlined when he served out the final game of the set to love.
