Zverev stuns Alcaraz to reach Australian Open semifinals

Alexander Zverev stuns Carlos Alcaraz with a sublime display of serving to reach Australian Open semi-finals.

Germany's Alexander Zverev stunned second seed Carlos Alcaraz to reach the Australian Open semi-finals as a sublime display of serving took him to a 6-1 6-3 6-7(2) 6-4 victory on Wednesday.

Zverev landed 94 of 111 first serves throughout the three hour, five minute contest and even when Alcaraz threatened a remarkable comeback he showed great composure to seal victory.

In his seventh Grand Slam semifinal, Zverev will need similar accuracy as he takes on Russia's Daniil Medvedev.

Alcaraz was outplayed for almost three sets but belatedly found his A-game to win a third-set tiebreaker with a mind-boggling flurry of outrageous winners.

Sixth seed Zverev was suffering from blood blisters on his feet during a riveting fourth set but held firm though to withstand the Alcaraz attack. His metronomic serving and bullet-proof backhand got him over the winning line against a top-five opponent for the first time at a Grand Slam.

"When you're up 6-1 6-3 5-2 against a player like Carlos you start thinking because we are all human," Zverev said on court.

"Your brain starts going and it's not always helpful but I'm happy I got there in the end. I fought back pretty well in the fourth set and didn't let go."
