Carlos Alcaraz powered into the semi-finals of the US Open on Wednesday as rival Daniil Medvedev battled through a brutal heatwave to join the Spaniard in the last 4. Defending champion Alcaraz moved to within one win of a potential dream final with Novak Djokovic with an emphatic straight sets victory over German 12th Alexander Zverev. Zverev had emerged as a dark horse after a marathon five-set win over Italy’s sixth seed Jannik Sinner on Monday. But the German’s hopes of extending his stay in New York were obliterated by a devastatingly clinical performance from Alcaraz, who completed a 6-3, 6-2, 6-4 win in 2hr 30min on the Arthur Ashe Stadium court.
