Carlos Alcaraz raced into an Australian Open quarter-final against Alexander Zverev on Monday, producing a fearsome display in a straight-sets win over unseeded Serbian Miomir Kecmanovic. The second seed -- seen as the biggest threat to defending champion Novak Djokovic -- did not face a single break point in a dominant performance, rolling over his opponent 6-4, 6-4, 6-0 in one hour 49 minutes. The Spaniard, who chose not to play any competitive tennis in the build-up to the first Grand Slam of the year, said he "did everything perfectly".
