Carlos Alcaraz stunned by Tomas Machac in Shanghai Masters quarter-final
Machac came into this quarter-final contest with confidence having been deadlocked with Alcaraz at one-set all in last month’s Davis Cup, only to have to retire because of cramps. “I knew that I had a chance (to win), but you never know, even with a set and 5-4 it’s still so far from winning the match,” Machac added.
