World number two Carlos Alcaraz has been knocked out of the Shanghai Masters in straight sets by 33rd-ranked Tomas Machac, losing 7-6 (7/5), 7-5 on Thursday.

No. 2-ranked Carlos Alcaraz's 12-match winning streak was ended by Tomas Machac 7-6 (5), 7-5 in the Shanghai Masters quarterfinals on Thursday. It was No. 33 Machac's third tour-level quarterfinal, and the Czech player proved more than a match for the four-time major-winning Spaniard as he earned his second win over a top-five opponent this year in two hours.

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.
