Alexander Zverev to face Dominic Thiem at US Open 2020 final Alexander Zverev beat Pablo Carreno Busta 3-6, 2-6, 6-3, 6-4, 6-3 and reached the US Open final. He will play against Dominic Thiem for the title. "I actually looked at the scoreboard when I was down two sets to love," Zverev said. "I was like, 'I can't believe it. I'm playing in a semi-final, I'm supposed to be the favorite and I have no chance, I'm playing that bad. "So I knew I had to come up with better tennis and I knew that I had to be more stable." Zverev made 36 unforced errors in the first two sets compared to just 12 for Carreno Busta as the nerves of the occasion seemed to get the better of him. Double fault followed double fault and a string of misplaced, nervy forehands allowed Carreno Busta to build a sizable lead. But Zverev began to seriously cut down on his mistakes in the third set, upping his service game and taking control of rallies with more powerful, accurate groundstrokes. It continued to be a nervy, error-strewn affair, though, with both players appearing overwhelmed at times with coming so close to reaching their first tennis major final. Zverev hit eight double faults overall to Carreno Busta's one. Zverev recorded 57 unforced errors to 44 for Carreno Busta. But the tall German smashed way more winners, 71 to 37. "I'm through to my first Grand Slam final and that's all that matters," Zverev said. "I couldn't be happier, but there's still one more step to go for me," he added.
