Thiem into U.S. Open final Dominic Thiem defeated Daniil Medvedev 6-2 7-6(7) 7-6(5) to reach the U.S. Open 2020 final where he will face Zverev. "For sure (it was) the toughest straight-sets win I ever had because could have been easily completely different," said Thiem. Thiem seized the early momentum inside the Arthur Ashe Stadium, handily carrying the first set without dropping a single first-serve point, but a double fault and a forehand error saw him hand Medvedev the break and the early lead in the second. Thiem spent the remainder of the set playing catch up, converting on a critical break to level the score 5-5 before tMedvedev dragged it into a tiebreak. Medvedev kept his energy up as he traded blows with his opponent, triumphing in an epic, 33-shot rally early in the tiebreak, but his efforts came up short. "He just doesn't miss when I play with his rhythm. So I tried to destroy that a little bit with lot of slices, with also high balls with a lot of spin. That was what was the plan," Thiem said. Thiem, who had a trainer examine his ankle before the third set, slipped and fell twice in the match, unfurling a string of frustrated exclamations the second time he did so. But he regained his cool to survive yet another tiebreak and clinched the affair with a power forehand and a roar. "I played my best tennis then toward the end of the sets," said Thiem, who saved six of eight break point opportunities during the match, committing a dozen fewer unforced errors than his opponent. "Both tiebreaks were amazing. Tiebreaks are mentally a tough thing. I don't like them at all to be honest," he said. "I'm really happy to be through. It was a great semi-final." Medvedev, who fired off a dozen aces on the match, showed shades of his bad boy persona seen in his 2019 run to the U.S. Open final. He offered a sarcasm-drenched apology in the first set after crossing to the other side of the net to lobby for a late challenge, earning a violation in the process. "I think I killed someone, right?" he said to a tournament supervisor in the stands, adding to the umpire, "My sincere apologies for crossing the net."
